Which of the followings does not come within central dogma?

Correct answer: D. All of the above

  • A. Synthesis of DNA
  • B. Synthesis of mRNA
  • C. Synthesis of protein
  • D. All of the above

Explanation

This process involves the creation of new DNA strands through DNA replication. In this process, a DNA molecule serves as a template for the synthesis of a new complementary DNA strand. Messenger RNA (mRNA) is synthesized in a process called transcription. During transcription, RNA polymerase enzyme reads the DNA template and synthesizes a complementary mRNA molecule, which carries the genetic information from DNA to the ribosome for protein synthesis. This process, known as translation, involves the synthesis of a protein from mRNA. Ribosomes read the mRNA molecule and use it as a template to assemble amino acids into a polypeptide chain, which folds into a functional protein. All of the options listed-synthesis of DNA, synthesis of mRNA, and synthesis of protein-are indeed part of the central dogma of molecular biology. None of them is excluded from this fundamental principle.

About Chromosomes

Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
