DNA structure and Replication

Front

What type of bond joins the two strands of nitrogenous bases in DNA?

Back

Hydrogen bonds

Front

What enzyme removes the RNA primer during DNA replication?

Back

Exonuclease

Front

What are the building blocks of nucleic acids?

Back

Nucleotides, which are composed of a sugar, a phosphate group, and a nitrogen base.

Front

What is the sugar component of DNA?

Back

Deoxyribose

Front

True or False: The leading strand is synthesized continuously, while the lagging strand is synthesized discontinuously.

Back

True

Front

What are the three components of a nucleotide?

Back

A sugar, a phosphate group, 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 difference between the leading strand and the lagging strand in DNA replication?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments called Okazaki fragments.

Front

What is the function of helicase in DNA replication?

Back

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

Front

What are Okazaki fragments?

Back

Short segments of DNA synthesized on the lagging strand during DNA replication.
