Answer #1

1. not all mutations are necessarily harmful some are beneficial too. some mutations help in adapting the changing environment, some help in survival.mutations are also responsible for evolution process.

2. some do not result in change but most results in different amino acid sequences. some synonymous substitutions occur which results in different codon triplet but same protein due to the degeneracy of codon.

3. in point mutation one nucleotide is changed which results in codon change thus produce different amino acid whereas in frameshift mutation insertion-deletion of nucleotides occur resulting in change of sequence.

Section C – Mutation of SARS-CoV-2 Over Time All viruses accumulate mutations over time, and different classes of viruses have different mutation rates based on the fidelity with which their genomes are replicated. Viral mutations can affect the accuracy of tests, the efficacy of vac- cines, and virulence (the ability to spread, the seriousness of illness, etc.). In this section you will compare a number of sequenced genomes from clinical samples during the first several months of the COVID-19 outbreak...

The mutation can occur in a restriction site, causing a change in the cutting pattern for restriction enzymes. b.
