Question

What is the difference between recombination and mutation?

Answer 1

Recombination:

1. Recombination is the process of breaking and recombining segments of DNA to create new allele combinations.
2. This recombination mechanism generates genetic variation at the gene level.
3. It represents species-specific variances in DNA sequences.

Mutation:

1. A mutation is a change in the DNA sequence that can arise as a consequence of erroneous nucleotide base or bases incorporation during replication or transcription, or as a result of environmental influences such as UV light, radiation, or mutagens.

Difference between recombination and mutation:

Recombination	Mutation
1. Recombination is the exchange of DNA strands that results in novel nucleotide rearrangements.	1. A mutation is a heritable, irreversible alteration in the nucleotide sequence of a gene or chromosome.
2. Rearrangement of a chromosomal segment	2. An alteration in the genome's nucleotide sequence
3. Homologous recombination, site-specific recombination, and transposition are the three forms.	3. Point mutations, frameshift mutations, and chromosomal mutations are the three kinds.
4. This happens during the preparation of gametes.	4. It can be caused by mistakes in DNA replication.
5. The majority occur naturally.	5. It is caused by environmental mutagens.
6. Change the genome on a massive scale.	6. It causes minor alterations to the genome.
7. The primary evolutionary force	7. Less contribution to the evolution
8. Large-scale reorganisation of species' genomes, resulting in the evolution	8. It generates new alleles, bringing genetic variety to a certain population.
