Answer:

Crop rotation

Explanation:

Plant obtain nutrients from the soil. Plantation of crops in soil depletes nutrients from the soil. Crop rotation is one of the methods used for maintaining the nutrient levels and thereby, the productivity of the soil. Crop rotation includes plantation of different crops in the same field. For example, farmers plant legume crops after the non-legume crops. Leguminous plants have Rhizobium bacteria in their root nodules. These bacteria fix nitrogen and restore the lost nitrogen from the soil.

  • In the mRNA; A will be complementary to U
  • In tRNA; U will be complementary to A

The mutation does not affect the structure of the protein and is called a silent mutation.

<h3>What is a mutation?</h3>

A mutation is a change that occurs in the sequence of nucleotides of a gene.

The mutation that changes the base G in the DNA to A will result in the following corresponding changes in the mRNA and tRNA:

  • In the mRNA; A will be complementary to U
  • In tRNA; U will be complementary to A

The mutation does not result in any changes since the amino acid coded for by the mRNA has more than one codon coding for it.

This type of mutation is called a silent mutation.

In conclusion, some mutations occurring in genes have no effect on the proteins the gene codes for.

How many nucleotides encode the identity of one of the 20 amino acids and is called a codon
m_a_m_a [10]

the size of a Codon is 3 nucleotides.

The 20 amino acids are encoded by combinations of four nucleotides

If a codon were two nucleotides, the set of all combinations could only encode 16 amino acids.

since Codons are made up of three nucleotides, the set of all combinations can encode 64 amino acids. {i.e. 64 different combinations of four nucleotides taken three at a time.} But of the total of 64 codons, 61 encode amino acids and 3 specify termination of translation.

I hope this Helps!
