Answer #1

Answer-

The mutation is Missence mutation which is characterized by when the change of a single base pair causes the substitution of a different amino acid in the resulting protein. In both the sequence cytosine is changed with guanine. This is conservative missense mutation.

Nonsense mutation means coding sequence is replace by stop codon, deletion means delete the base and frameshift means deletion or insertion in a DNA sequence that shifts the way the sequence is read

    The gene encoding protein Bog in E. coli has been changed by a point mutation in its open reading frame. Originally the gene encoded a 108 amino acid long functioning protein whose amino acid composition favored nonpolar and negatively charged amino acids. After the mutation it encodes a 110 amino acid long non-functioning protein that is now rich in polar uncharged amino acids and positively charged amino acids. Which mutation scenario best explains this observation. A) A frame-shift caused by...

    Researchers have identified a gene in humans that (when mutant) causes severe dwarfism and mental retardation. This disorder is inherited in an autosomal recessive manner, and the mutant allele is known to be a loss-of-function mutation. The same gene has been found on mice, although a mutant version of the gene has not been discovered in mice. To develop drugs and an effective therapy to treat this disorder, it would be extremely useful to have a mouse model of the...
