<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.
 
        
             
        
        
        
A codon is a tree letter nucleotide sequence in the mRNA. The tRNA anticodon attached to the corresponding amino acid recognizes the mRNA codon. A single amino acid can have more than one codon. 
The serine codon can be one of the following:
<span>TCT, TCC, TCA, TCG, AGT, AGC</span>
 
        
             
        
        
        
Answer:
Yes , it is possible to make sequence of another nucleotide.
Explanation:
An adenine on one strand is always paired with a thymine on the other strand, and a guanine is always paired with a cytosine . If the sequence of nucleotides on one strand is known, the sequence of the other strand will be automatically known as well.
