Front

What is nucleotide excision repair?

Back

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

Front

What sugar is found in RNA?

Back

Ribose, which differs from DNA's deoxyribose.

Front

What nitrogenous base is found in RNA instead of thymine?

Back

Uracil.

Front

What are the two main types of nitrogenous bases in nucleic acids?

Back

Purines and pyrimidines.

Front

Define purine.

Back

A type of nitrogenous base that includes adenine (A) and guanine (G).

Front

Define pyrimidine.

Back

A type of nitrogenous base that includes cytosine (C), thymine (T), and uracil (U).

Front

What is the role of RNA in protein synthesis?

Back

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

Front

What is the structure of RNA?

Back

RNA is a single-stranded polymer of nucleotides.

Front

What is the significance of complementary base pairing in DNA?

Back

It ensures accurate replication and transcription of genetic information.

Front

What is the difference between DNA and RNA?

Back

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