Answer:
Deletion of two nucleotides.
Explanation:
Every amino acid coded by 3 nucleotides.
12:3=4 (amino acids)
6:3=2 (2 amino acids)
3:3=1 (1 amino acid)
After all of these mutations sequence amino acids change, but after continues stay the same.
Only deletion of 2 nucleotides will completely altered all amino acids encoded without mutation.
Answer:
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O).
Explanation:
This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.

Answer:
As resources are depleted, population growth rate slows and eventually stops: This is known as logistic growth. The population size at which growth stops is generally called the carrying capacity (K), which is the number of individuals of a particular population that the environment can support.
