The lysine amino acid will provide a positive charge to the active site. If this mutation changed all of the lysine amino acids to aspartic acid, it will produce an enzyme having a negative charge.
<h3>Mutations and amino acids</h3>
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an organism.
A mutation that alters the active site of an enzyme will invariably affect its catalytic activity.
A mutation that involves a change in lysine (positive) to aspartic acid (negative) will produce a protein having a net negative charge.

Explanation:
there are 20 amino acids in a protein
<span>The concept of cell signaling is a communication network that is responsible for majority of the cellular activities. It is important that if the cell is deprived of this ability it will soon die. Since a cell is able to correctly interact with it's environment and perceive it, they are able to repair tissues, develop, and become immune to normal tissue homeostasis.

The plants ploidy is decided based on the chromosome within the nucleus . Plant can be either heterozygous or homozygous.
The major distinction between homozygous and heterozygous individuals is that the former have two identical alleles while the latter have both dominant and recessive alleles. Over several generations, kids with the same characteristic are produced through self-breeding between homozygous individuals.
Heterozygous and homozygous chromosomes are seen in human beings. Allele pairings are categorized as Heterozygous and Homozygous. A heterozygous person possesses various alleles, whereas a homozygous person carries a pair of identical (RR or rr) alleles (Rr).
Let's take the gene for hair colour as an example. This gene has two alleles, one of which is responsible for black (r), and the other for black (R). On a homologous set of chromosomes, such as RR or rr, homozygous people will carry the same colour allele, but heterozygous people will carry distinct colour alleles.
Hence, depending on type allele can be homozygous or heterozygous.
