SEMESTER 2 FINAL EXAM STUDY GUIDE

Front

Define: RNA Polymerase

Back

RNA polymerase is the enzyme that synthesizes RNA from a DNA template during transcription.

Front

What is the role of the nucleus?

Back

The nucleus controls cell activities and stores genetic information.

Front

Which base is only found in RNA and not DNA?

Back

Uracil.

Front

List the three types of RNA and their functions.

Back

mRNA (messenger RNA) - carries genetic information; tRNA (transfer RNA) - brings amino acids; rRNA (ribosomal RNA) - forms ribosomes.

Front

What controls what enters and leaves the cell?

Back

The cell membrane.

Front

What is the function of mRNA?

Back

mRNA carries genetic information from DNA to the ribosome for protein synthesis.

Front

What is the function of tRNA?

Back

tRNA brings amino acids to the ribosome during protein synthesis.

Front

What is the function of rRNA?

Back

rRNA forms the structural and functional components of ribosomes.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

What is transcription?

Back

Transcription is the process of synthesizing RNA from a DNA template.
