A segment of DNA that codes for a specific protein.

What is the role of the promoter in transcription?

The promoter is the region where RNA polymerase binds to initiate transcription.

What is the difference between the template strand (antisense strand) and the nontemplate strand (sense strand) in transcription?

The template strand is used by RNA polymerase to create the mRNA, while the nontemplate strand is not directly involved in mRNA synthesis.

I can describe how DNA is transcribed into RNA and translated into proteins.

During transcription, enzymes use a strand of DNA to produce mRNA, which carries the genetic information.

During translation, each set of three bases on the mRNA, called codons, codes for a specific amino acid.

The start codon, AUG, initiates translation by coding for methionine, while stop codons terminate translation.
