In gene mutation, adenine is replaced by guanine. It is
1. Frame-shift mutation
2. Transcription
3. Transition
4. Transversion

Degeneration of genetic code is due to
1. First member of codons
2. Second member of codons
3. Third member of codons
4. Entire codons.

Which of the following features of genetic code does allow bacteria to produce human insulin by recombinant DNA technology?

1. Genetic code is specific

2. Genetic code is not ambiguous

3. Genetic code is redundant

4. Genetic code is nearly universal

Production of human protein in bacterial genetic engineering is possible because           
1. Human chromosome replicate bacterial cell
2. Mechanism of gene regulation is identical in humans and bacteria
3. Bacterial cell can undertake RNA splicing
4. Genetic code is universal

What is not for genetic code
1. It is unambiguous
2. A codon in mRNA is read in a non-contiguous fashion
3. It is nearly universal
4. It is degenerate
