Biology

1. If this insertion is within the coding region of a viralprotein, will this insertion result in a frameshift for the rest ofthe protein? How do you know?

2. The insertion mutation is in a gene that codes for a proteinon the surface of the virus, probably a glycoprotein. Assume thatthis protein is involved in attachment to a host cell. How might achange in a protein involved in attachment change the potentialhosts for the virus?

3. How long does it typically take a person's adaptive immunesystem to make antibodies in a primary response to an antigen? Isit likely that a person would have memory B cells that recognize anew surface protein on the virus? Why or why not?

4. Why is a population unlikely to have herd immunity to a virusthat has a new protein on its surface?

1 If this insertion is within the coding region of a viral protein will this insertion result in a frameshift for the rest of the protein How do you know Insertion is of single nucleotide Then definitly this will cause the change in the coding region reading frame and protein Example 5 ATT TGC CGA GGC AAT TTA 3 is the coding sequence and it is followed by insersion of a A in the codon TGC then the sequence will be 5 ATT TGA CCG AGG CAA TTT A 3 Comparing the reading frame of both the sequnces we can see only first codon will code for the same amino acid while rest of the codon sequence has been changed leading to the complete change in amino acid sequenceas comapre to 5 ATT TGC CGA GGC AAT TTA 3 Insertion is of two nucleotide This also will cause the change in the reading frame of codons and amino    See Answer
