V posttranslational modification purine ring structure mRNA splicing M B-form DNA structure protein s Incorrect. At least one of your selections is incorrect. The core structure of DNA and the structure of bases are not altered to regulate gene expression.

Solution

Answer:

Posttranslational modification

mRNA splicing

Protein synthesis

Explanation:

Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product. These products are often proteins, but in non-protein coding genes such as transfer RNA (tRNA) or small nuclear RNA (snRNA) genes, the product is a functional RNA.

Proteins are synthesized by the following ways.

Transcription:

mRNA is produced from DNA template strand. The mRNA produced immediately DNA is called immature mRNA as it contains introns, non-protein coding regions. So the introns are removed by mRNA splicing mechanism. Then final mRNA is produced. This involves in translation.

Translation:

Synthesis of proteins based on the sequence of codons in the mRNA. After forming the protein, the protein undergoes some modifications called posttranslational modifications to be function proteins.
