Unit 6 AP Biology Gene Expression and Regulation

Front

Which direction is DNA synthesized during DNA replication?

Back

5' to 3'.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase cannot start replication independently; it requires a primer.

Front

Which strand is read for transcription in DNA?

Back

The 3' to 5' noncoding strand.

Front

Is DNA more stable than RNA?

Back

True.

Front

What is the function of the coding strand in transcription?

Back

The coding strand has the same sequence as the mRNA (except for T being replaced by U).

Front

What is the significance of the 5' and 3' ends of DNA?

Back

They indicate the directionality of the DNA strand, which is crucial for replication and transcription.

Front

What is a primer in DNA replication?

Back

A short nucleic acid sequence that provides a starting point for DNA synthesis.

Front

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

Back

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

Front

What is transcription?

Back

The process of copying a segment of DNA into RNA.

Front

What is the role of RNA polymerase?

Back

RNA polymerase synthesizes RNA from a DNA template during transcription.
