Answer:

A mutation that changes the first letter to 'C' is called<u> Frameshift mutation.</u>

Explanation:

  • <u>  FRAMESHIFT MUTATION </u> -: A frameshift mutation is a genetic mutation of a number of nucleotides caused by indels (insertions or deletions) in a DNA sequence that is not divisible by three.  A frameshift mutation (also called a framing error or a reading frame shift) The addition or deletion may alter the reading frame (the grouping of codons) due to the triplet nature of gene expression by codons resulting in a completely different translation from the root. A frameshift mutation, instead of being added or removed, is not the same as a single-nucleotide polymorphism in which a nucleotide is substituted. In general, a frameshift mutation will cause the reading of the codons to code for various amino acids after the mutation. The first stop codon ("UAA", "UGA" or "UAG") encountered in the series would also change the frameshift mutation. The polypeptide that is formed will be abnormally short or abnormally long, and most likely will not be functional.
  • Hence, the answer is<u> Frameshift Mutation</u>.

Types Of Steroids and Their Functions
1. Anabolic Steroids
-increase muscle mass
-promote cell growth and division
-testosterone( natural anabolic steroid) is used in sperm production, development of male reproductive organs and emergence of male secondary sexual characteristics.
-stimulates bone and muscle growth.

2. Sex Hormones
-produced by adrenal cortex
-aid in development of gametes
-prepare females for pregnancy, menstruation

Help me please <br><br> Who answer correctly you get breinly
Genrish500 [490]

All cells have cell membranes, and the membranes are flexible. So animal cells can have various shapes, but plant cells only have the shapes of their cell walls. That's nice for plants, because it gives them the ability to grow up and out, where they can get lots of sunlight for making their food.
