Three human disorders−−fragile X syndrome, myotonic dystrophy, and Huntington's disease−−are conceptually linked by a common mode of molecular upset. Choose the phenomenon that links these disorders. Three human disordersfragile X syndrome, myotonic dystrophy, and Huntington's diseaseare conceptually linked by a common mode of molecular upset. Choose the phenomenon that links these disorders. All three are caused by disparate genes, but each gene was found to contain repeats of the same trinucleotide sequence. All three are X-linked, but each gene was found to contain repeats of the same trinucleotide sequence. All three are caused by disparate genes, but each gene was found to contain repeats of a unique trinucleotide sequence. All three are X-linked, but each gene was found to contain repeats of a unique trinucleotide sequence.
Answer:
The correct answer is ''All three are caused by disparate genes, but each gene was found to contain repeats of a unique trinucleotide sequence.''
Explanation:
Four groups of trinucleotide repeats related to DNA expansion have been characterized in the human genome. CGGI GCC, CAGIGTC, CTGIGAC and recently GW CTT sequences. The CGGl GCC sequences are usually located in the noncoding regions of different genes and when expanded they associate with fragile sites on the chromosomes. The CAGIGTC repeats are part of the coding region and are related to different neurodegenerative disorders. You can try to make a classification depending on the unit that is repeated, having on one side a group that are caused by repeats of the CAG trinucleotide (cytosine, adenine, guanine). Huntington's disease (HD) is a progressive disorder of motor, cognitive and psychic function. The disease is inherited in an autosomal dominant manner, and is caused by the expansion of CAG trinucleotide repeats in exon 1 of the gene called huntingtin (HTT or IT-15). Unstable mutations have also been found in which the repeat unit does not is composed of three nucleotides, if not four, such as type 2 myotonic dystrophy, where the tetranucleotide CCTG repeats. Fragile X Syndrome consists of an abnormal expansion of the cytosine-guanine-guanine trinucleotide (CGG) in the FMR1 gene, which prevents intellectual disability and also influences the formation of connective tissue
How does the double-helical structure of DNA explain how the molecules can be copied or replicated?
A. Because of base pairing, each strand has all the information to serve as a template for the other strand.
B. Each strand receives the information from the DNA polymerase attached to the replication fork.
C. The nitrogenous bases on one strand are copied to the other strand.
D. The nitrogenous bases line up on each strand and are attached to each other.
Answer:
A. Because of base pairing, each strand has all the information to serve as a template for the other strand.
Explanation:
Deoxyribonucleic acid (DNA) is a molecule composed of two antiparallel polynucleotide chains. This double helix serves as a template for its own duplication. DNA templating refers to the process by which a portion of the DNA molecule in a single strand is used as a template to be copied by complementarity base pairing. According to base-pairing rules, Adenine (A) always pairs with Thymine, while Guanine (G) always pairs with Cytosine (C). These nucleotide bases are each linked with their complementary base by hydrogen bonding. When base pairs separate, the hydrogen bond acceptor and donor groups of each strand allow the addition of nucleotides and synthesis of new DNA strands, a process catalyzed by specialized enzymes (DNA polymerases).

Compare how natural selection selects for organisms with beneficial traits over those with less beneficial traits for an environment.
Natural selection is the process by which animals adjust to their environments.The environment affects natural selection. Natural selection does not prefer characteristics that are better in some fundamental way.
Natural selection is a process that favors heritable characteristics that boost an organism's chances of survival and enable additional reproduction.
What decides which features are adaptive during the course of natural selection?
In evolutionary biology, we decide which qualities in an organism are adaptive (caused by natural selection) and which are non-adaptive or spandrels by examining whether or not that particular trait was something that arose for its current purpose would be an adaptation.

You go on an expedition into the Amazon Rainforest to look for new species before they are destroyed by logging. You find one organism you have never seen before. You run a few tests to determine what kind of organism it is. You determine that it is multicellular and that it first digests, then absorbs nutrients from the environment around it. What classification fits it best?
A. Plantae
B. Animalia
C. Fungi
D. Protista
Multicellular is a cellular classification where the organism is made of more than one cell. The multicellular organism that absorbs nutrients best fits in the kingdom of Fungi. Thus, option C is correct.
What is Kingdom Fungi?
Fungi is one of the five kingdoms that are characterized by eukaryotic organisms with multicellular structures. They contain microorganisms that are heterotrophs and cannot make their own food. They absorb the nutrients from decaying organic materials.
The fungal mycelia and filaments called hyphae allow fungi like mushrooms and molds to absorb nutrients and minerals from the surrounding. They digest the nutrients with the help of enzymes.
Therefore, option C. the Fungi first digest then absorb nutrients from the environment.

The Trans-Pecos ecoregion in the western portion of Texas
receive less than 38 cm of rainfall a year and has little soil due
to overgrazing by farm animals. What catastrophic event is
most likely the cause the most weathering and erosion in the
least amount of time in this ecoregion?
1.Wildfire
2.Earthquake
3.Flood
4.Tornado
Answer:
3.Flood
Explanation:
Flood is the catastrophic event which is the main cause of the most weathering and erosion in the least amount of time in this ecoregion because there is no vegetation present in this region and the soil is vulnerable for erosion. Flash-flooding and rapid runoff are agents of erosion in the Trans-Pecos ecoregion of Texas whenever the rainfall occurs. Vegetative is very important for preventing soil erosion so the people of this region has to stop overgrazing in this area in order to avoid more erosion of the soil.

The immune system has both specific and nonspecific defenses against viral infections. Which statement describes a nonspecific response of the immune system in fighting viral infections?
A. T cells are produced to search out and destroy the viruses.
B. Memory B cells are activated to rapidly respond to the viral infection.
C. Plasma cells quickly replicate and release antibodies that bind to the viruses.
D. Virus-infected cells produce interferons that lead to the inhibition of viral replication
Answer:
C
Explanation:
I just did this same question
Virus-infected cells produce interferons that lead to the inhibition of viral replication and act as a nonspecific response of the immune system in fighting viral infections. Therefore, the correct statement is option D.
What are interferons?The immune system has two types of responses to viral infections: specific and nonspecific. Interferons are signaling molecules produced by virus-infected cells to activate antiviral defenses, such as apoptosis in infected cells. This refers to the nonspecific response of the immune system in fighting viral infections
Interferons function by alerting the immune system about the presence of a viral infection. Interferons can also stimulate the production of other immune cells, such as natural killer cells and macrophages to eliminate the infected cells.
Interferons have been also used to treat viral infections, such as hepatitis B, and are the nonspecific defenses that act as a first line of defense against viral infections.
Therefore, interferons that lead to the inhibition of viral replication are the nonspecific response of the immune system in fighting viral infections.

Frameshift mutation are the result of what occurrence?
Explanation:
A frameshift mutation (also called a framing error or a reading frame shift) is a genetic mutation caused by indels (insertions or deletions) of a number of nucleotides in a DNA sequence that is not divisible by three. Due to the triplet nature of gene expression by codons, the insertion or deletion can change the reading frame (the grouping of the codons), resulting in a completely different translation from the original. The earlier in the sequence the deletion or insertion occurs, the more altered the protein. A frameshift mutation is not the same as a single-nucleotide polymorphism in which a nucleotide is replaced, rather than inserted or deleted. A frameshift mutation will in general cause the reading of the codons after the mutation to code for different amino acids. The frameshift mutation will also alter the first stop codon ("UAA", "UGA" or "UAG") encountered in the sequence. The polypeptide being created could be abnormally short or abnormally long, and will most likely not be functional.

What are the four ways that RNA differs from DNA?
Answer:
RNA is single standard while DNA is double standard
RNA contains the sugar ribose, while DNA contains deoxyribose.
RNA contains uracil, while DNA contains thymine.
RNA can leave the nucleus, while DNA cannot.
Explanation:
RNA is a single-stranded structure while DNA is a double-stranded structure while the former containing the uracil base and the latter containing the thymine base.
What is the difference between RNA and DNA?DNA stands for deoxyribonucleic acid which is defined as a double-stranded molecule consisting of a long chain of nucleotides whereas RNA stands for ribonucleic acid which is defined as a single-stranded molecule consisting of a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating but RNA does not replicate on its own.
The base pairing is of DNA is as follows: GC (Guanine pairs with Cytosine) A-T (Adenine pairs with Thymine) while the base pairing of RNA is as follows: GC (Guanine pairs with Cytosine) A-U (Adenine pairs with Uracil). RNA has the sugar ribose while DNA has the sugar deoxyribose. DNA is located in the nucleus of a cell and in the mitochondria while the RNA is found in the cytoplasm, nucleus and in the ribosome.
Thus, RNA is a single-stranded structure while DNA is a double-stranded structure while the former containing the uracil base and the latter containing the thymine base.
