Which process involves copying the DNA sequence into mRNA?

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

Answer: (B)

The process of copying the DNA sequence into mRNA is known as transcription. During transcription, an enzyme called RNA polymerase binds to a specific region of the DNA and unwinds the DNA strands. It then reads the exposed DNA template strand and synthesizes a complementary strand of messenger RNA (mRNA) by joining together nucleotides that are complementary to the DNA template. This mRNA strand carries the genetic information necessary for protein synthesis from the nucleus to the cytoplasm, where it will later be translated into a protein during the translation process. In this context, replication refers to the process of duplicating the entire DNA molecule to ensure that each new cell receives a complete set of genetic instructions, while translation is the subsequent step where the mRNA is read by ribosomes and translated into a specific sequence of amino acids to form a protein. Inversion is a type of chromosomal mutation where a segment of DNA is flipped and reinserted into the chromosome, which does not pertain to the process of synthesizing mRNA. Therefore, transcription is the only process involved in creating mRNA from a DNA template.
