DNA- Cooper

Front

What is a checkpoint in the cell cycle?

Back

A checkpoint is a critical point where stop and go signals can regulate the cell cycle, ensuring proper division and function.

Front

Which enzyme is responsible for unzipping the DNA double helix during replication?

Back

Helicase is the enzyme that unwinds and separates the two strands of the DNA double helix.

Front

What role does DNA polymerase play in DNA replication?

Back

DNA polymerase adds complementary nucleotides to the growing new strand during DNA replication.

Front

What are Golgi bodies?

Back

Golgi bodies are organelles that package proteins to be shipped out of the cell.

Front

What forms the backbone of the DNA ladder?

Back

The sides (backbone) of the DNA ladder are formed by deoxyribose sugar and phosphate.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA.

Front

What is the role of primase in DNA replication?

Back

Primase synthesizes a short RNA primer that provides a starting point for DNA synthesis.

Front

What is the function of ligase in DNA replication?

Back

Ligase is the enzyme that joins Okazaki fragments on the lagging strand during DNA replication.

Front

What is the significance of the double helix structure of DNA?

Back

The double helix structure allows for the stable storage of genetic information and facilitates replication.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.
