Explanation:

Polycomb group (PCG) gene mutants cause ectopic expression of Antennapedia (Antp) and other homeotic genes. The PCG protein encoded by the PgG gene has a domain that binds to methylated histone H3. This finding supports which of the following hypotheses?
a) that PCG mutants lack Antp mRNA compared to the wildtype
b) that PCG repress transcription by interacting with chromatin
c) that PCG binds to Antp genes and serves as a transcription activator
d) that PCG activates Antp genes in tissues
e) that PCG is allosteric activator of RNA polymerase II

Answers

Answer:

b) that PCG repress transcription by interacting with chromatin

Explanation:

The Polycomb-group (PcG) proteins are evolutionarily conserved proteins in all higher eukaryotes which are involved in establishing epigenetic silencing of developmental genes. In animals, the PcG proteins are well known to form complexes capable of silencing target developmental genes by modulating chromatin structure during embryo development. In Drosophila melanogaster, the Polycomb repressive complex 2 (PRC2) is known to catalyze the trimethylation of lysine 27 on histone H3 (i.e., H3K27me3), thereby silencing homeotic (Hox) developmental genes. The core of the Drosophila PRC2 complex is composed of Enhancer of zeste [E(​z)], Suppressor of zeste 12 [Su(z)12], and Extra sex combs (Esc) proteins. The E(​z) protein is a well-known histone methyltransferase that maintains the methylation status of Hox genes, thereby silencing their expression during embryo development.

Explain the advantages to a plant of having its cell membranes surrounded by cell walls

Answers

Answer:

Advantage of cell walls

It protect and support the cell .

To give difinite shape for the cell.

Having cell walls surrounding cell membranes provides several advantages to plants, including structural support, protection against pathogens, regulation of water balance, and prevention of cell rupture.

The cell wall is a rigid structure located outside the cell membrane in plant cells. It is composed primarily of cellulose, a complex carbohydrate. Here are the advantages of having cell walls:

Structural Support: Cell walls provide mechanical support to plant cells and help maintain the overall shape and structure of the plant. They allow plants to stand upright and withstand environmental forces such as wind or gravity. The cell walls of adjacent plant cells are interconnected, forming a strong network that provides stability to the plant as a whole.

Pathogen Protection: The cell wall acts as a physical barrier against pathogens such as bacteria and fungi. It prevents the entry of pathogens into the plant cells, reducing the risk of infection. Additionally, the cell wall can contain antimicrobial compounds and other defense molecules that provide further protection against pathogens.

Water Regulation: The cell wall plays a crucial role in regulating water balance within plant cells. It helps maintain turgor pressure, which is essential for cell expansion and overall plant growth. The cell wall allows water to enter and exit the cell in a controlled manner, preventing excessive water uptake or loss.

Cell Rupture Prevention: The rigid cell wall helps prevent cell rupture or bursting when the internal pressure within the cell increases. It provides strength and stability to the cell, allowing it to withstand internal pressure changes without bursting.

Overall, the presence of cell walls in plant cells offers significant advantages in terms of structural support, protection against pathogens, regulation of water balance, and prevention of cell rupture. These advantages contribute to the overall health, growth, and survival of plants in diverse environmental conditions.

According to the endosymbiotic theory, why was it adaptive for the larger (host) cell to keep the engulfed cell alive, rather than digesting it as food select all that apply

Answers

Answer:

It provides ATP.

Explanation:

It is adaptive for the larger host cell to keep the engulfed cell alive, instead of digesting it as food because the engulfed cell provides energy in the form of adenosine triphosphate (ATP) to the host cell. The larger host cell is able to survive in anaerobic conditions with the help of engulfed cell alive so that's why we can conclude that the larger host cell keep the engulfed cell alive instead of killing it and used as a food source.

Enhancerless GFP reporter constructs used in research conducted in mice contain a generic mouse gene promoter (TATA box) followed by a transcription start site and then a GFP gene cDNA. When such enhancerless reporter gene constructs are integrated into random locations in the mouse genome, about 10% of the time, high levels of tissue-specific GFP expression are detected, even though the reporter gene construct itself has no enhancer. How is this possible

Answers

Answer:

the reporter gene can randomly insert near to an enhancer sequence which can induce its expression

Explanation

Enhancers are genetic sequences capable of activating gene expression by binding to specific proteins (e.g., transcription factors). Enhancers can regulate the expression of nearby genes located thousands of nucleotides away, i.e., over several kilobases away. In the human genome, it is well known that enhancers are scattered across the 98% of the genome. In this case, it is expected that the reporter GFP gene construct is randomly inserted near an enhancer sequence (a 10% chance of insertion), thereby being regulated by that enhancer.

Explain how privatizing endangered species (private ownership) will save them from extinction. Give an example. (approximately 5 sentences) Also, explain why prohibiting trade of endangered species will accelerate their rate of extinction. Be sure to discuss the tragedy of the commons, and the prisoner's dilemma in your answer. (About 8sentences)

Answers

Answer: The privatization of endangered species will reduce their chances of extinction.

Explanation:

The endangered species are those species which are low in numbers, their population will reduce or extinct in the near future. The privatization of these animals will protect them from dangers of trafficking, predation, habitat loss, and death due to natural disaster. Animals like elephant, monkey, tiger, lion are privatized to protect their extinction.

The trade of hides, teeth, ivory, flesh, horn, and other parts of the endangered animals will accelerate the rate of extinction. Prohibition of trade will allow the agents of trafficking to get chances of killing and stealing animal parts to a large number.

The tragedy of commons suggests that people neglect the well being of the society for personal gain. Those people who exploit the resources from endangered species causing harm to the nature as they are responsible for reducing biodiversity.

Extinction is defined as the elimination of species due to natural or human-made factors. The species are necessary to preserve the ecosystem and biodiversity.

The private ownership of endangered species (species on the verge of extinction)can save the species from extinction. Private ownership will reduce their chances of being hunted, exported, traded, predation, loss of habitat, and death due to natural calamities.

The animals like elephants, monkeys, crocodiles, snakes, and lions are categorized in private ownership to prevent their extinction.

The ban on the trading of endangered species can or might save the species from extinction, but it can also backfire leading to market booms. The prohibition will allow the traders to follow animal trafficking and stealing, which can result in an increased rate of extinction.

The killing of animals for ivory, fur, skin, teeth, and flesh and selling them in the black market will lead to an increase in their rate of extinction.

The tragedy of commons refers to the negligence of the social surrounding for personal gains. The people who exploit resources and cause harm to endangered species are indirectly harming nature, and therefore responsible for the reduction in biodiversity.

Genes are segments of DNA located on chromosomes. A gene mutation is defined as an alteration in the sequence of nucleotides in DNA. This change can affect a single nucleotide pair or larger gene segments of a chromosome. DNA consists of a polymer of nucleotides joined together. During protein synthesis, DNA is transcribed into RNA and then translated to produce proteins. Altering nucleotide sequences most often results in nonfunctioning proteins. Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop the disease. Gene mutations can be generally categorized into two types: point mutations and base-pair insertions or deletions.

Explanation:

In a swimming pool or lake, the water is a
liquid until the water temperature gets
down to 0 C or 32. F. Water in pools
stays liquid during Las Vegas winters,
with just a bit of ice forming if it gets really cold overnight. Even when it is
chilly in January and February (usually 15° C or 60° F), water stays liquid.
Then, when our area's temperature gets really hot in the summer (usually
about 40° C or 100. F), the water in the pool is still a liquid. It would have
to be 100. C or 212. F for the water in the pool to boil! Those
temperatures have never happened on Earth.
Remember, though, that water does not have to boil to turn to a gas.
Some of the water evaporates at all temperatures. Water temperature is a
measure of the average kinetic energy of its molecules. Some molecules
have more kinetic energy than others. The molecules that have enough
kinetic energy to break the bonds with other molecules can leave the
liquid and move off into the air. That is why you have to keep filling up the
swimming pool, even though it is not boiling.
Why does water stay liquid over a large range of temperatures? Hint:
Think about molecular structure.
