DNA Structure, DNA Replication & Protein Synthesis Review

Front

What are Chargaff's rules?

Back

Chargaff's rules state that in DNA, the amount of adenine (A) equals thymine (T), and the amount of guanine (G) equals cytosine (C). This means A=T and G=C.

Front

What is the primary function of DNA?

Back

The primary function of DNA is to store genetic information.

Front

What type of biomolecule is DNA Polymerase?

Back

DNA Polymerase is a protein.

Front

During which phase of the cell cycle do point mutations occur?

Back

Point mutations occur during the S phase of the cell cycle.

Front

What is the complementary DNA strand for the mRNA sequence UUCGAG?

Back

The complementary DNA strand is AAGCTC.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), guanine (G), and cytosine (C).

Front

What is the role of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix, separating the two strands to allow replication.

Front

What is transcription in the context of protein synthesis?

Back

Transcription is the process of copying a segment of DNA into mRNA.

Front

What is translation in the context of protein synthesis?

Back

Translation is the process where ribosomes synthesize proteins using the information carried by mRNA.
