DNA structure and Replication

Front

In eukaryotes, which organelle is DNA usually found in?

Back

Nucleus

Front

What protein holds the DNA strands apart to allow DNA to be replicated?

Back

Single-Stranded Bind Protein

Front

What are the 4 nitrogen bases in DNA?

Back

Adenine, Thymine, Cytosine, and Guanine

Front

Why is DNA important?

Back

It serves as the blueprint for traits of all living things.

Front

What enzyme unwinds and unzips the double helix during DNA replication?

Back

DNA Helicase

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What are nucleotides made of?

Back

A phosphate group, a sugar (deoxyribose), and a nitrogenous base.

Front

What is the role of DNA Polymerase in DNA replication?

Back

DNA Polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the function of RNA Primase in DNA replication?

Back

RNA Primase synthesizes a short RNA primer to initiate DNA synthesis.

Front

What is the difference between leading and lagging strands in DNA replication?

Back

Leading strand is synthesized continuously, while lagging strand is synthesized in short fragments (Okazaki fragments).
