Front

What is DNA replication?

Back

The process by which a DNA molecule makes a copy of itself, resulting in two identical DNA strands.

Front

What are nucleotides?

Back

The monomers of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the role of helicase in DNA replication?

Back

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

Front

What is the function of DNA ligase?

Back

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

Front

What is the nucleolus?

Back

A small, dense region within the nucleus where ribosomal RNA (rRNA) is produced and ribosomes are assembled.

Front

What is the central dogma of molecular biology?

Back

The central dogma describes the flow of genetic information from DNA to RNA to protein.

Front

What is transcription?

Back

The process of synthesizing RNA from a DNA template.

Front

What is translation?

Back

The process of synthesizing proteins from mRNA at the ribosome.

Front

What are ribosomes made of?

Back

Ribosomes are composed of ribosomal RNA (rRNA) and proteins.

Front

What is the function of primase?

Back

Primase is the enzyme that synthesizes a short RNA primer to initiate DNA replication.
