Semester One Final Study Day One

Front

Which enzyme performs transcription (DNA-->RNA)?

Back

RNA polymerase

Front

What is the central dogma of biology?

Back

DNA -> RNA -> Protein

Front

Why is DNA replication considered semi-conservative?

Back

Each new DNA molecule consists of one old strand and one new strand.

Front

What is the name of the structure/shape of a DNA molecule?

Back

Double Helix

Front

Which nitrogen base is only found in RNA?

Back

Uracil

Front

What is the function of DNA polymerase?

Back

DNA polymerase synthesizes new DNA strands during replication.

Front

What role does helicase play in DNA replication?

Back

Helicase unwinds the DNA double helix, separating the two strands.

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 a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes facilitate the translation of mRNA into a polypeptide chain.
