Answer:

How will you describe a mutation?

Mutation Definition. A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. A Mutagen is an agent of substance that can bring about a permanent alteration to the physical composition of a DNA gene such that the genetic message is changed.

What is a gene?

In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.

What are the two general classification of mutations?

Two major categories of mutations are germline mutations and somatic mutations. Germline mutations occur in gametes. These mutations are especially significant because they can be transmitted to offspring and every cell in the offspring will have the mutation. Somatic mutations occur in other cells of the body.

How is point mutation different from frame-shift mutation?

mutation where the protein production machinery can continue to read the DNA sequence after the mutation. It may result in a protein with sections missing or substituted, but since the majority of the protein remains intact it may still be partially functional. See also out-of frame mutation.

What are the three types of point mutation? Describe each?

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.

how is point mutation different from frame shift mutations?

Point mutations change a single nucleotide. Frameshift mutations are additions or deletions of nucleotides that cause a shift in the reading frame.

what are the three types of point mutation?describe eeach?

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.
