Option D
<u>Explanation</u>:
- "SCID" is "inherited immune system disorder" which happen due to abnormalities in the response of both T and B cells which are needed for the proper functioning of the immune system.
- VDJ occurs in genetic recombination occurring in the early or developing stages of lymphocytes.
- Somatic recombination is also a part of VDJ which results in immunoglobulin's, which is "defining feature" of the immune system and the same which causes severe combined immunodeficiency.

Explanation:
During the translation of mRNA to protein, the nascent polypeptide chain that is formed is not yet a functional protein right after translation. The polypeptide must then undergo another series of processing and packaging and may even need another protein(s) to completely form a functional moiety. Generally, for this a mix of chaperones may be needed to complete the protein synthesis pathway.
The answer is A. The diversity of species can occur in both plant kingdom and animal kingdom. And for the biological change, the sudden change over a single generation is called mutation. Only when the mutation is good for environment and the environment has changed, the mutation will be reserved and pass to the generations. Then <u>gradually</u> it will accounts the diversity of species.
