Transcription and Translation

Genes are used as templates to create a variety of useful types of RNA.

• Transcription

• Translation

• RNA Polymerase

• Elongation

What is the second step of gene expression?

• Initiation

• Transcription

• Translation

• Protein Synthesis

The goal of transcription is to...

• to create a polypeptide

• to make RNA copies of specific genes

• to unwind so the enzyme can ''read'' the bases in one of the DNA strands

• strand of DNA is synthesized as RNA polymerase moves along DNA

creates complementary strand of RNA using DNA template.

RNA polymerase binds to promoter to ____ transcription.

RNA transcript is released and polymerase detaches from DNA, which then rewinds itself into a double-helix, ______.

• changed

• doubled

• unchanged

• polymerase

method by which tRNA helps mRNA direct the creation of proteins.

• Translation

• Termination

• Transcription

• Elongation

Where does protein synthesis occur?

• Nucleus

• Mitochondria

• Cytoplasm

• Ribosome

What happens when RNA polymerase constructs an RNA strand in the 5' to 3' orientation?

• A transcribing RNA polymerase releases the DNA template and the nascent RNA

• Each new nucleotide is added to the 3' end of the strand

• Proteins are created

• Nothing

RNA polymerase elongates in the ____ direction
