Which term describes the molecule formed during transcription that carries the genetic code to the ribosome?

• A. Heredity
• B. Genetic screening
• C. mRNA
• D. Alleles

Answer: (C)

The key idea is that messenger RNA is the carrier of the genetic code from DNA to the ribosome. During transcription, an RNA copy of a gene is made, and this molecule—mRNA—contains codons that specify the sequence of amino acids for a protein. It travels from the nucleus to the ribosome, where the information it carries is read to assemble the protein during translation. The other terms refer to broader concepts (heredity), tests (genetic screening), or gene variants (alleles), none of which describes the molecule that conveys the code to the ribosome. mRNA is the specific messenger that bridges DNA and protein synthesis.
