After a mutation at a genetic locus the character of an organism changes due to the change in :

A

protein structure

B

DNA replication

C

protein synthesis pattern

D

RNA transcription pattern

Text Solution

Verified by Experts

The correct Answer is:
A
Normally , genetic information floes from DNA `to` mRNA `to` protein . Hence ,any change in nucloetides due to the mutation , would result in change in the structure of protein/ enzyme which moght result in some change in the organism.

Mutations And Genetic Code

Sudden and heritable change ina character of an organism is called:

Assertion: During mutation a gene may undergo a sudden change in expression due to the change in composition. Reason: Some genes mutate more than one and have more than two alleles.

Read the following text and answer the following questions on the basis of the same: Mutation is sudden, discontinuous variation in genotype of an organism due to a change in its chromosomes and genes. Variation in DNA is a result of mutation. It is of three types : Gene mutation, chromosomal aberrations and gametic mutation. Gametic mutation is a change in chromosome number that brings effect on the phenotype, it is of two type - aneuploidy and euploidy. Mutation can be artificially produced by certain agents called mutagen. There are two major types of mutagens: physical and chemical mutagen. Change in sequence of nucleotide in DNA is known as ...... .
