Answer:
4. Circular Chromosomes
Explanation:
We know that eukaryotic chromosomes consist of double-stranded DNA.
But prokaryotic chromosomes are actually circular, which is very different from eukaryotic.
Answer:
The mutation could cause serious damage in the replication process.
Explanation:
The TATA box is a DNA region that indicates the point where, processes like replication can begin. The mutation of this could cause that replication never begins, and therefore, protein synthesis is stopped. This severe complication would lead the cell to death in a short amount of time, for example.
A structural adaption is the physical features of an organism, or some can be behavioral. With that said, your answer will be D.) A mouse has long whiskers that are used to detect temperature changes.
Buffers in our blood are able to neutralize changes in the bloods pH.
Different amino acids means difference DNA sequences, which means they are distantly related.
Further understanding: if you look at identical twins, they are closely related to each other because they have almost the same DNA, which will code for the same amino acids, which will lead to the same phenotype or appearance.
To summarize, the greater the amino acid differences the less related they are and vice versa
