Question

Explain the 3 types of mutations that occur when genes change?

Answer 1

Answer:

The three are substitution, insertion,and Deletion

Explanation:

Substitution- a mutation where one base pair is replaced by another base pair

Insertion-Change the number of DNA bases in a gene by adding a piece of DNA. if this is done then the protein made by the gene may not function

Deletion-a DNA Molecule not copied during the replication process. It can be as small as a single nucleotide or as big as an entire chromosome. The absence of this molecule can cause a genetic disease

Answer 2

Answer:

There are three types of DNA Mutations: base substitutions, deletions and insertions. Single base substitutions are called point mutations, recall the point mutation Glu -----> Val which causes sickle-cell disease. Point mutations are the most common type of mutation and there are two types.

3 Types of DNA

There are three types of DNA Mutations

 1. Base substitutions,

2. Deletions

3. Insertions.

What are different types of genes called?

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.
