The following segment of DNA is the template strand transcribed into mRNA:
      5'-...GACATGGAA...-3'

What is the sequence of mRNA created from this sequence?

Key Concepts

Transcription

Transcription is the process by which the genetic information encoded in DNA is copied into messenger RNA (mRNA). During transcription, RNA polymerase binds to the DNA template strand and synthesizes a complementary RNA strand, replacing thymine (T) with uracil (U). This process is essential for gene expression, allowing the information in DNA to be translated into proteins.

Template Strand

The template strand of DNA is the strand that serves as a guide for RNA synthesis during transcription. It is read in the 3' to 5' direction, allowing the RNA polymerase to synthesize the mRNA in the 5' to 3' direction. Understanding which strand is the template is crucial for determining the correct mRNA sequence.

mRNA Sequence

The mRNA sequence is a single-stranded RNA molecule that is complementary to the DNA template strand. In mRNA, adenine (A) pairs with uracil (U) instead of thymine (T). The sequence of mRNA is critical for the subsequent translation process, where it serves as a template for synthesizing proteins based on the genetic code.
