What is the role of transcription in molecular genetics?

• Produces a DNA copy of a gene

• Produces an RNA copy of a gene

• Produces a polypeptide using mRNA

• Stores information in units called genes

What does messenger RNA (mRNA) do?

• Stores information in units called genes

• Becomes part of a functional protein

• A temporary copy of a gene that contains information to make a polypeptide

• Produces a polypeptide using mRNA

What is the function of translation in the central dogma?

• Produces a DNA copy of a gene

• Produces an RNA copy of a gene

• Produces a polypeptide using the information in mRNA

• Stores information in units called genes

What is the primary function of Messenger RNA (mRNA)?

• To carry amino acids to ribosomes

• To encode the sequence of amino acids in a polypeptide

• To regulate mRNA stability and translation

Which type of RNA helps form the large and small ribosomal subunits?

• Messenger RNA (mRNA)

• Transfer RNA (tRNA)

• Ribosomal RNA (rRNA)

• MicroRNA (miRNA)

What is the role of Transfer RNA (tRNA) in protein synthesis?

• To encode the sequence of amino acids in a polypeptide

• To carry amino acids to ribosomes and bind them to mRNA

• To form the large and small ribosomal subunits

• To regulate mRNA stability and translation

Which type of RNA is involved in regulating mRNA stability and translation?

• Small nuclear RNA (snRNA)

• MicroRNA (miRNA)
