BIOL 300 Final Review

Front

What is a gene?

Back

A segment of DNA that encodes instructions for protein synthesis.

Front

Why is the lagging strand called 'discontinuous replication'?

Back

The lagging strand is synthesized in short segments (Okazaki fragments) rather than continuously.

Front

What is Position Effect Variegation?

Back

The variable expression of a gene due to its position in the genome, often near heterochromatin.

Front

What is a transposon?

Back

An enzyme that recognizes inverted repeats, excises it, and moves it to a new location.

Front

What is an allele?

Back

An allele is a variant form of a gene.

Front

What is DNA replication?

Back

The process by which a DNA molecule makes a copy of itself.

Front

What are Okazaki fragments?

Back

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

Front

What is heterochromatin?

Back

A tightly packed form of DNA that is generally not expressed.

Front

What is the role of RNA polymerase?

Back

An enzyme that synthesizes RNA from a DNA template during transcription.

Front

What is the central dogma of molecular biology?

Back

The process by which DNA is transcribed to RNA, which is then translated into protein.
