Question

Identify the correct sequence of molecules, as a gene goes from coded information in the nucleus, to the product the cell wants to make. A) DNA -> messenger RNA -> transfer RNA -> protein B) DNA -> transfer RNA -> messenger RNA -> protein C) DNA -> transfer RNA -> protein -> messenger RNA D) Protein -> messenger RNA -> transfer RNA -> DNA

Answer 1

Answer:

The correct option is A) DNA -> messenger RNA -> transfer RNA -> protein

Explanation:

The process by which DNA is converted into mRNA is known as transcription. During this process, the DNA unwinds from the place where transcription has to take place. Both the strands of the DNA double-helix get separated. The DNA polymerase adds nucleotides and generates a complementary strand again the region which has to be transcribed. This generated strand is known as the mRNA. The mRNA contains Uracil except for thymine.

Modifications in the mRNA are done so that it can be transported outside the cell. The process of making proteins from mRNA is termed as translation.
