    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 produces a protein with the same amino acid sequence as the original codon and causes a disease because the protein does not function properly.

    Male cats only have one X chromosome. This is the key reason they cannot express both orange and non-orange colors simultaneously in the same way as female cats do. Female cats have two X chromosomes, which allows for the possibility of having one orange gene and one non-orange gene, resulting in a calico or tortoiseshell pattern. In contrast, male cats have one X chromosome (which can carry the orange gene) and one Y chromosome, limiting their coat color expression to either orange or non-orange, but not both.

    The false statement is:
**Chromosomes contain RNA only.**
Chromosomes primarily contain DNA, which is the genetic material that carries the genetic code of an organism. While RNA can be involved in gene expression and can be found in cells, it is not the main component of chromosomes.

    The correct response would be:
**Positive transcription factor affinity has a greater influence because you cannot turn genes on without it.**
Positive transcription factors play a crucial role in initiating the transcription of genes into mRNA, which is the first step in gene expression. If transcription factors are not present or are weakly bound, the associated genes may not be expressed, leading to lower protein levels.

    The most likely effect of the mutation is:
**The mutated codon produces the same protein as the original codon and does not cause a disease.**
This scenario is known as a "silent mutation," where a substitution in the DNA codon does not change the amino acid produced due to the redundancy in the genetic code. As a result, the protein maintains the same amino acid sequence and is likely to function normally.

**transcription and translation, respectively.**
Transcription is the process by which DNA is used to produce mRNA, while translation is the process in which mRNA is used to synthesize proteins.
