How is genetic information transmitted from DNA to RNA?

• A. Replication
• B. Translation
• C. Transcription
• D. Translocation

Answer: (C)

Genetic information is transmitted from DNA to RNA through the process of transcription. During transcription, the DNA molecule unwinds and serves as a template for synthesizing a complementary RNA strand. This process occurs in the nucleus of eukaryotic cells, where the enzyme RNA polymerase binds to the promoter region of a gene, initiating the synthesis of the RNA transcript.

Once transcription is complete, the RNA molecule undergoes processing (such as capping, polyadenylation, and splicing) before it becomes mature mRNA that can be transported out of the nucleus for translation into proteins. This process is fundamental for gene expression, as it allows the information encoded in the DNA to be converted into a functional product, which is typically a protein, through subsequent translation.

In contrast, replication refers to the process of copying DNA to ensure that each daughter cell receives an identical set of DNA during cell division. Translation is the process in which the messenger RNA (mRNA) is decoded by ribosomes to synthesize proteins. Translocation typically refers to the movement of a segment of DNA or genes from one location to another within a genome or the movement of ribosomes along the mRNA during translation. Each of these processes plays a distinct role in the flow of
