Answer:
In point mutation,the gene is affected however in chromosomal mutations,there is change in the structure or number of the chromosomes
The primary distinction among point mutation and chromosomal mutation is, the point mutation is a small mutation in which basically a single base pair of the either DNA or RNA encoding changes, whereas chromosomal mutation is a large-scale mutation in which the chromosome structure changes.
What is mutation?
A mutation is an alteration in an organism's DNA sequence. Mutations can take place as a consequence of mistakes in DNA replication during cell division, mutagen exposure, or viral infection.
Mutagens are environmental factors that results in mutations. Mutagens can be either radiation, chemicals, or infectious agents.
In living organisms, there are two kinds of genetic mutations namely point mutation and chromosomal mutation.
The nucleotide sequences are usually altered in both cases. As a result, all these types of mutations can result in fatal diseases.
The main difference between point mutation and chromosomal mutation is that point mutation is a small-scale mutation that changes a single base pair of the DNA or RNA encoding, whereas chromosomal mutation is a large-scale mutation that changes the chromosome structure.
Thus, this is the comparison between the types of mutation.
