the non-coding regions.
b) the non-coding regions of the human genome are not
functional.
c) the first draft of human genome is generated using the Sanger
sequencing technology.

2) Below are three mutations found in the coding
sequence of a gene:
1. a single
nucleotide substitution of A to
G that changes TTA (Leucine) to TTG (Leucine);
2. a single
nucleotide substitution of a
nucleotide T to A that changes TTA
(Leucine) to TAA (STOP)
3. the insertion of a
nucleotide T that changes TTA (Leucine)
to TTT(Phenylalanine) A;
Which of the following accurately assign the types of these
three mutations?
1. synonymous; 2. missense; 3. frameshift
1. conservative missense; 2. nonsense; 3. nonconservative
missense
1. synonymous; 2. nonsense; 3. frameshift
1. missense; 2. nonsense; 3.frameshift
