The correct response is:
male cats only have one X chromosome
This is because male cats (XY) have only one X chromosome, while female cats (XX) can inherit one orange allele and one non-orange allele, allowing for the expression of both colors.
Why are male cats unable to express both orange and non-orange colors simultaneously in the same way as female cats?(1 point)
Responses
only female cats inherit non-orange genes
only female cats inherit non-orange genes
male cats only have one X chromosome
male cats only have one X chromosome
male cats have a dominant Y chromosome
male cats have a dominant Y chromosome
only female cats inherit orange genes

Chromosomes primarily contain DNA, which carries the genetic code of an organism. While chromosomes may be associated with RNA (such as during transcription), they do not consist solely of RNA.
What has a greater influence on protein levels?

Positive transcription factor affinity has a greater influence because you cannot turn genes on without it.
Positive transcription factor affinity has a greater influence because you cannot turn genes on without it.
Positive transcription factor affinity has a greater influence because you cannot start reading mRNA without it.

The statement that is most accurate in terms of greater influence on protein levels is:
Polymerase affinity has a greater influence because mRNA cannot be translated into proteins without it.
While transcription factors are critical for initiating transcription, the actual process of synthesizing mRNA (which is later translated into proteins) heavily relies on the binding and activity of RNA polymerase. If polymerase cannot bind effectively to the DNA, mRNA transcription does not occur, thereby directly impacting protein levels.
A normal allele for a gene has more base pairs than the mutated form of the allele. Which type of mutation occurred?(1 point)
Responses
base pair insertion
base pair insertion
base pair separation
base pair separation
base pair deletion
base pair deletion
base pair substitution
Responses
base pair insertion
base pair insertion
base pair separation
base pair separation
base pair deletion
base pair deletion
base pair substitution
The correct response is:
base pair deletion
If a normal allele has more base pairs than the mutated form, it indicates that some base pairs have been removed from the sequence, which is characteristic of a deletion mutation.
A DNA codon that codes for a certain protein undergoes a substitution mutation. The new codon codes for the same amino acid as the original codon. What is the most likely effect of the mutation?(1 point)
Responses
The mutated codon prevents the protein from forming and causes a disease.
The mutated codon prevents the protein from forming and causes a disease.
The mutated codon produces a protein with the same amino acid sequence as the original codon and causes a disease because the protein does not function properly.
The mutated codon produces a protein with the same amino acid sequence as the original codon and causes a disease because the protein does not function properly.
The mutated codon produces a different protein than the original codon and causes a disease because the protein does not function properly.

The most likely effect of the mutation is:
The mutated codon produces a protein with the same amino acid sequence as the original codon.
This type of mutation is known as a synonymous or silent mutation, which does not change the amino acid sequence of the protein. Consequently, it is unlikely to cause a disease unless there are other factors involved, such as regulatory elements that might be affected. However, the provided options seem incomplete, so it is also important to consider that such mutations typically have no functional effect on the protein itself.
