Answer is letter B: prophase
Answer:
An amino acid can be encoded by more than one codon.
Explanation:
Codons are triplets of nucleotides in mRNA that are used for the protein synthesis (translation). A codon specifies a single amino acid, but there are exceptions. tRNA molecule contain anticodons, triplets of nucleotides that are complementary to codons. So, during the translation, tRNA carries the amino acid, that corresponds to the codon in mRNA.
Degenerate genetic code (more than one codon can code for the same amino acid) is important, because when point mutation occurs it is possible that the amino acid remains unchanged.
<u>Answer:- </u> Decomposition
<u>Explanation:- </u>
Decomposition is a natural process that occurs in the environment to break down organic substances into simpler substances.
- All the living organisms that die, are decomposed and their bodies are broken down into simpler substances such that the nutrients are released into the soil.
- The plants are then able to absorb these nutrients from the soil and thus, the nutrient cycling goes on as the organisms feeds on it.
- Not only the dead animals but also the fallen leaves and other parts of the plant gets decomposed as they die.
- The process of decomposition is carried out by living organisms present in the soil such as bacteria. Such organisms are called as decomposers.
