what are mutations? name 3 kinds of mutations.

Sagot :

Answer:

Three kinds of mutations are:

1. Point Mutations: These are changes that involve the substitution of a single DNA base with another base. Point mutations can be further categorized into:

  • Silent Mutations: Mutations that have no effect on the amino acid sequence.

  • Missense Mutations: Mutations where an amino acid is changed into a different one.

  • Nonsense Mutations: Mutations that result in changing an amino acid-coding codon to a stop codon, leading to premature termination of translation.

2. Insertions: These mutations involve the insertion of extra base pairs into the DNA sequence.

3. Deletions: Mutations where a section of DNA is lost or deleted from the sequence.

These types of mutations can have various effects on the resulting proteins and can impact the overall function of the organism.

Mutations

A mutation is a change in DNA. Mutations can affect one codon, several codons, or the entire DNA sequence that comes after the mutation. Most mutations affect the genes, but some can even affect chromosomes.

There are several different types of mutations. 3 of them are:

1. Substitution mutations. When these mutations occur, one codon is substituted for another one.

2. Deletion mutations. When they occur, a codon is deleted from the sequence.

3. Insertion mutations. When this happens, an extra codon is insterted into the DNA sequence.
