Answer:
it affects the hardness of the shells because calcium has a high reactivity which causes the shell to be hard
Explanation:
The answer is the base sequence of gene's promoter.
DNA is a two-stranded helix. One strand is called a template strand, the other one is called a coding strand. The template strand is copied into mRNA, and the coding strand is complementary to the template strand. RNA polymerase, an enzyme responsible for transcription, has to recognize the right strand before transcription begins. So, it recognizes one or more short sequences on the coding strand. This is the base sequence of gene's promoter. Thus, the complementary strand is the template strand.
Generally speaking, it would not affect the organism. For humans, we regularly replace our cells in our body, so even when our cells die, we are fine.
The particular polymorphism normallyused for DNA fingerprinting is the Short Tandem Repeats (STRs) which are non-conding portions of DNA that consist of a repeating genetic sequence of DNA code.
