Molecular DNA Review

Front

What is a codon?

Back

A codon is a three-base sequence of mRNA that codes for a single amino acid.

Front

Where does translation occur in the cell?

Back

Translation occurs in the cytoplasm.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) is responsible for delivering amino acids to the ribosome during translation.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of DNA and RNA, consisting of a sugar, phosphate, and nitrogen base.

Front

What is transcription?

Back

Transcription is the process of converting DNA into mRNA.

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the difference between DNA and RNA?

Back

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

Front

What are the three types of RNA?

Back

The three types of RNA are mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, synthesizing proteins by linking amino acids together.

Front

What is an anticodon?

Back

An anticodon is a three-base sequence on tRNA that is complementary to a codon on mRNA.
