Answer:
Explanation:
I read it's has to do with the amount of nucleic acid that must be synthesized. RNAs are tiny compared to DNA, so there is little selection pressure for speed. Also, multiple RNA polymerases can initiate simultaneously, effectively increasing the synthesis rate
Answer:An obstacle to the triviality of the first issue includes the fact that DNA polymerase replicates DNA at a rate of 10-15 times faster than RNA polymerase transcribes DNA so that these enzymes inevitably collide if they attempt to function concurrently and co-directionally
Explanation:
At any given instant, only a fraction of the genome (total DNA) is being transcribed. Consequently, speed is not necessary.

Which of the following effectively describes the situation of someone with an inherited predisposition to cancer such a familial adenomatous polyposis or BRCA-associated familial breast cancer?
a) Every cell of their body contains a gain-of-function allele of an oncogene
b) Most cells in their body contain multiple cancer-causing mutations
c) If they get malignant cancer, somatic mutations will not have been a factor
d) Their cancer will most likely arise in their germ cells, not their somatic cells
e) None of the answers effectively describes the situation
f) Every cell of their body contains a defective, loss-of-function allele of a tumor suppressor gene
Answer:
Every cell of their body contains defective , loss of function allele of a tumor suppressor gene
Explanation:
Tumor suppressor genes - They encode Proteins that inhibit cell proliferation . But due to Loss of functional alleles in Tumor suppressor genes it leads to the development of different cancers
Every cell of the body comprises of a defective and loss-of-function allele of a tumor suppressor gene.
The presence of defective and non-functioning tumor suppressor gene is responsible for the happening of cancer disease because the tumor suppressor gene slow down the process of cell division as well as repair mistakes occur in DNA molecule. When the tumor suppressor genes can't perform its function properly, it causes out of control growth of cell, which can lead to cancer disease so we can conclude that tumor suppressor gene is responsible for the cancer disease.

If E is the allele for brown eyes and e is the allele for blue eyes, which of these genotypes will allow the individual yo have the phenotype of blue eyes
Answer:
Since blue eyes are a recessive gene, the genotype will need to be ee.
If E is the allele for brown eyes and e is the allele for blue eyes, the genotype that will allow the individual to have the phenotype of blue eyes is ee.
What is genotype?Genotype is the part of the genetic makeup of an organism that determines a specific characteristic (phenotype) of that organism.
According to this question, E is the allele for brown eyes and e is the allele for blue eyes. This suggests that E is the dominant allele while e is the recessive allele.
Therefore, the genotype that will allow the individual to have the phenotype of blue eyes is ee.

1. In a parent pea plant with the allele pair Gg, what is the probability that one gamete will contain the G allele? Why?
2. In a parent pea plant with the allele pair GG, what is the probability that one gamete will contain the g allele? Why?
3. In a parent pea plant with the allele pair gg, what is the probability that one gamete will contain the g allele? Why?
Answer:
If the gamete will get either G or g, the probability will be 1/2 of getting G.
Explanation:
all question 3 answer is that. Because all 3 of question are same. only repeated three times
In a parent pea plant with the allele pair Gg, the probability that one gamete will contain the G allele is 0.5. This is because there are two possible outcomes in which one must definitely fall. So, it is 1/2.
What is Allele?Alleles may be characterized as the alternative form or versions of a gene that are responsible for particular traits in living organisms. They carry a code of genetic sequences within generations.
In a parent pea plant with the allele pair GG, the probability that the gamete will contain the g allele is zero. This is because there is no presence of allele g that can be determined within any gametes. So, it is not possible to get g in the pair allele of GG.
In a parent pea plant with the allele pair gg, the probability that one gamete will contain the g allele is 1 or 100%. This is because both carry g alleles. So, the probability is 100%.

What is a major role that fungi play in ecosystems
Answer:
Fungi play a crucial role in the balance of ecosystems. They colonize most habitats on earth, preferring dark, moist conditions. They can thrive in seemingly-hostile environments, such as the tundra. However, most members of the Kingdom Fungi grow on the forest floor where the dark and damp environment is rich in decaying debris from plants and animals. In these environments, fungi play a major role as decomposers and recyclers, making it possible for members of the other kingdoms to be supplied with nutrients and to live.

Human blood type is an example of which two types of genetics?
A. Multiple alleles and Polygenic inheritance
B. Codominance and Incomplete dominance
C. Incomplete dominance and Polygenic inheritance
D. Codominance and Multiple alleles
The Human blood type is determined by the presence or absence of specific antigens on the surface of red blood cells polygenic inheritance involves the contribution of multiple genes to a single trait, which is not the case for human blood type determination. D
The genetics of blood types involves both codominance and multiple alleles.
Codominance refers to a situation where both alleles of a gene are expressed simultaneously and equally in the phenotype.
In the case of blood type, there are three alleles involved: A, B, and O.
Alleles A and B are codominant, meaning that if an individual inherits both A and B alleles, both antigens will be present on their red blood cells. This results in blood type AB.
Multiple alleles refer to the existence of more than two alternative forms of a gene in a population.
In the case of blood type, individuals can have blood type A (AA or AO genotype), blood type B (BB or BO genotype), blood type AB (AB genotype), or blood type O (OO genotype).
The A and B alleles are dominant over the O allele, which is recessive.
Therefore, the combination of codominance and multiple alleles explains the inheritance patterns of human blood types.
This system allows for the expression of both A and B antigens (codominance) while accommodating the presence of multiple alleles (A, B, and O) in the population.
It is important to note that blood type inheritance is not an example of incomplete dominance or polygenic inheritance.
Incomplete dominance refers to a situation where neither allele is completely dominant, resulting in an intermediate phenotype.
Therefore, human blood type is an example of both codominance (expressing multiple alleles simultaneously) and multiple alleles (more than two alternative forms of a gene exist within a population).

Answer:

A new mammal has been discovered in the thickly-forested mountains of Papua New Guinea. The squirrel-like animal lives in the canopy of the forest and has a diet rich in leaves. On occasion, however, the animal drops to the ground to quickly fill its cheeks with its own fecal droppings, for ingestion once it is safely back in the trees. The GI tract of this animal would most likely include ________. a simple stomach and a large cecum a simple stomach, a short small intestine and colon, and a small cecum a four-chambered stomach and long intestines a long small intestine with abundant villi and an appendix at the beginning of the large intestine a short intestine and no cecum
Answer:
a simple stomach and a large cecum
Explanation:
Some small animals whose diet is prominent in vegetable matter, have an elongated cecum.
This segment of the digestive tract might be considered the first portion of the large intestine. It receives undigested material, and through the action of bacterial flora, is able to ferment this material and mix its contents with mucous substances to facilitate absorption. Through the walls, the organ can absorb fluids, salts, and nutrients.
The cecum size varies according to the animals. In small organisms, such as the new squirrel-like herbivore animal from the example, the cecum is enlarged. An elongated surface is useful for better digestion and absorption.
