MCQ

A human gene product can be produced by genetically engineered bacteria. This is possible, because the:

✓
Genetic code is universal.
B
Human chromosome can replicate in bacterial cell.
C
Bacterial cell can carry out the splicing reaction.
D
Mechanism of gene regulation is identical in humans and bacteria.

✓

Answer

Correct option: A.

Genetic code is universal.

The genetic code is the set of rules by which information encoded within genetic material $\text{(DNA}$ or $\text{mRNA}$ sequences$)$ is translated into proteins by living cells.
Biological decoding is accomplished by the ribosome, which links amino acids in an order specified by $\text{mRNA,}$ using transfer $\text{RNA (tRNA)}$ molecules to carry amino acids and to read the $\text{mRNA}$ three nucleotides at a time. The genetic code is highly similar among all organisms.
So, genetic code is called as universal.
