Replication, Transcription, and Translation

Front

What is the role of uracil in RNA?

Back

Uracil is a nitrogenous base found in RNA that pairs with adenine during RNA synthesis.

Front

What is the structure of DNA?

Back

DNA consists of two strands forming a double helix, with alternating phosphate groups and deoxyribose sugars.

Front

What is the first step in protein synthesis?

Back

The first step is transcription, where DNA serves as a template to produce mRNA.

Front

What is mRNA?

Back

mRNA (messenger RNA) is a type of RNA that carries genetic information from DNA to the ribosome for protein synthesis.

Front

What is the function of tRNA?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during translation, matching its anticodon with the mRNA codon.

Front

What is the product of transcription?

Back

The product of transcription is a strand of RNA.

Front

What is translation in protein synthesis?

Back

Translation is the process where ribosomes synthesize proteins using the information carried by mRNA.

Front

What determines the sequence of amino acids in a protein?

Back

The sequence of nucleotides in the mRNA determines the sequence of amino acids in a protein.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, linking amino acids together to form proteins.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid.
