Front

What is nucleotide excision repair?

Back

A form of DNA repair where the DNA molecule is unwound and separated in the region of nucleotide damage, damaged nucleotides are removed and replaced with new nucleotides using the complementary strand, and the DNA strand is resealed.

Front

Which base pairs with adenine in DNA?

Back

Thymine pairs with adenine, and cytosine pairs with guanine.

Front

What is the sugar found in RNA?

Back

Ribose is the sugar found in RNA, as opposed to deoxyribose in DNA.

Front

What nucleotide is found in RNA instead of thymine?

Back

Uracil is found in RNA instead of thymine.

Front

What is the role of a primer in DNA replication?

Back

A primer is a short stretch of RNA nucleotides required to initiate replication and allow DNA polymerase to bind and begin replication.

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, with two strands that spiral around each other.

Front

What type of bonds hold the two strands of DNA together?

Back

Hydrogen bonds hold the bases of one strand to the bases of the second strand in DNA.

Front

What is the function of RNA in cells?

Back

RNA functions in the process of forming proteins from the genetic code in DNA.

Front

What are the main differences between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose and thymine, while RNA is single-stranded and contains ribose and uracil.

Front

What is the significance of complementary base pairing in DNA?

Back

Complementary base pairing ensures accurate replication and transcription of genetic information.
