Answer:

Explanation:

Protein functions are so diverse because of the many unique three-dimensional structures protein polymers form. Despite such variety, proteins also share several specific structural characteristics in their monomers, the amino acids. Structural similarities among amino acids make protein synthesis a uniform and regulated process; however, each amino acid contains a unique structural component as well. Specific differences between each amino acid interact to create unique three-dimensional protein structures. Combined, the similarities and differences between amino acids explain how cells can build a diverse pool of proteins from the same set of building blocks. Protein synthesis involves building a polymer of amino acids with complex three-dimensional structure. Dehydration synthesis forms a peptide bond between amino acids and releases a water molecule.

Answer:

Allowing a small but controlled portion of a pest population to remain does less damage to ecosystems, soils, water, and air. Another feature of IPM would be making a habitat more complex, such as mazes, so it can slow the spread of parasites. No-till or low-till agriculture is another feature of IPM because this helps natural enemies of some pests to build up in the soil, whereas plowing destroys the habitats of these enemies.

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells

Answer:

All living things are made of cells; the cell itself is the smallest fundamental unit of structure and function in living organisms. In larger organisms, cells combine to make tissues, which are groups of similar cells carrying out similar or related functions.

Answer:

E.e. oregonesis

E.e. platensis

E.e. xanthoptica

E.e. croceater

E.e. eschscholtzii

E.e. klaubori

Explanation:

The species mentioned above are probably separate species from E.e. eschscholtzii, which arose through ring speciation that occurs when a species is geographically distributed in a circular pattern. After this distribution, geographic isolation occurs, causing individuals in each different region to evolve differently, becoming other species, even reaching the point where it is not possible to cross them.

Answer:

The correct answer would be: 3' - CGTATAAC - 5'

Explanation:

DNA molecule is a double-stranded molecule structure that has two distinct nucleotide chains joined together with hydrogen bonds between the nitrogenous bases of each strand. Adenine binds with thymine and cytosine binds with guanine by hydrogen bonds always in complementary strands.

These strands are complementary to one another as they have complementary bases in the complementary strand of one nucleotide chain of DNA. So,

5' - GCATATTG - 3' - DNA nucleotide of one strand

3' - CGTATAAC - 5' complementary strand

Explanation:

DNA has two chains of subunits and RNA has only one chain of subunits.

DNA or Deoxyribonucleic acid is a nucleic acid structure. Its function is to work as an original blueprint or the basic code for protein synthesis. A DNA molecule has deoxyribose sugar, it has lost an oxygen molecule from the 3' carbon.

It also has phosphates and nitrogenous bases like adenine (A), guanine (G), cytosine (C) and thymine (T) in a unique sequence. These sequences form two chains which are intertwined to form a double helix.

Ribonucleic acid or RNA is also a nucleic acid. This directly takes part in protein synthesis. It is an important nucleotide and has nucleic acid in long chains that are present in all living cells. It has ribose sugar. It has the same nucleotides as DNA except for uracil (U) replaces thymine (T).

The main role of RNA is to act as a messenger. It gets instructions from DNA and uses them for controlling protein synthesis. This is present in a single chain.

Therefore, DNA has two chains of subunits and RNA has only one chain of subunits.

Explanation:

Human immunodeficiency virus type 1 (HIV-1) enters target cells by first binding to the primary receptor CD4 and then to a coreceptor, generally one of the chemokine receptors CCR5 and CXCR4 (4). CD4 binding induces structural changes in the envelope (Env) glycoprotein that form and expose the coreceptor binding site. There are two main interactions between Env and coreceptor (13, 14, 25, 50, 51): the base of the third variable loop (V3) engages the N terminus of the coreceptor, while the crown of the V3 loop that includes the highly conserved GPGR/Q arch motif binds to the extracellular loops of the coreceptor, with the second extracellular loop of the coreceptor being particularly important (16, 25, 35, 48, 62). Although some HIV-1 strains are able to use a variety of different G protein-coupled receptors to gain entry into CD4+ cell lines, the great majority of these viruses use CCR5 and/or CXCR4 as coreceptors to infect primary cells (3, 4, 10, 23, 47, 66). CCR3, GPR15, APJ, and FPRL-1 are among the most frequently used alternative coreceptors when overexpressed on cell lines (11, 26, 43, 47, 57). Rare cases of HIV-1 strains that are able to use FPRL-1 and GPR1, but not CCR5 or CXCR4, have been reported (57); however, their in vivo relevance remains unknown.

To characterize the biological processes underlying HIV/simian immunodeficiency virus (SIV) transmission, we recently developed an experimental strategy that permits the identification, enumeration, and molecular cloning of transmitted/founder (T/F) viruses (28, 53). This strategy, which employs single-genome amplification (SGA) and direct amplicon sequencing of HIV/SIV RNA or DNA from the plasma or infected cells, makes it possible to infer the nucleotide sequence of the viral strain(s) that initiated productive infection weeks earlier (1, 28, 29, 37, 53, 58, 67). An important prediction of this approach has been that inferred T/F viruses are fully functional and encode all proteins necessary to establish a new infection. Indeed, this prediction has been borne out in numerous studies, which have shown that T/F viral genes as well as full-length genomes are biologically active. Sets of T/F Envs have been shown to mediate efficient virus entry in single-round infection assays, and they invariably use CCR5 as a coreceptor (28, 34). Similarly, T/F infectious molecular clones (IMCs) of HIV-1, SIVmac and SIVagm all produce replication competent virus that grow to high titers in primary CD4+ T cells (22, 38, 54).

MATERIALS AND METHODS

Amplification of the HIV-1 env gene. Serial plasma samples collected from an acutely infected plasma donor, ZP6248, were purchased from ZeptoMetrix. A total of seven plasma samples were collected between 12 February and 9 March 1997, and viral loads (VLs) were determined by the COBAS Amplicor HIV-1 monitor test.

Sequence analysis. All SGA amplicons were sequenced directly by cycle sequencing and dye terminator methods using an ABI 3730xl genetic analyzer (Applied Biosystems, Foster City, CA). Individual sequences were assembled and edited using the Sequencher program 4.7 (Gene Codes, Ann Arbor, MI). The env sequences were aligned using CLUSTAL W (60), and manual adjustment for optimal alignment was done using MASE (20).

Answer:

Punnet squares are basically how you can somewhat "predict" the outcome of gene pools.

Explanation:

As you can see, the capital letters (RY) are dominant alleles meaning they will be the trait that shows no matter what. the lower case letters (ry) show recessive traits and will only show if paired with another recessive gene.

Genotype is the actual makeup so the letters. (Rr, Ry, ry... etc.)

Phenotype is the trait that shows such as brown hair, blue eyes, etc.

Frequency is just how many times the gene shows up and put as a fraction or percent.
