Protein Synthesis (Gene Expression)

Front

What is the process of transcription?

Back

Transcription is the process by which the genetic information in DNA is copied into messenger RNA (mRNA). This occurs in the nucleus of the cell.

Front

What is translation in protein synthesis?

Back

Translation is the process where ribosomes synthesize proteins using the information carried by mRNA. It occurs in the cytoplasm.

Front

What is a codon?

Back

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

Front

What nitrogenous base is found in RNA but not in DNA?

Back

Uracil is found in RNA, replacing thymine which is present in DNA.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, facilitating the assembly of amino acids into proteins.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil instead of thymine.

Front

What is the function of mRNA?

Back

mRNA serves as a template for protein synthesis, carrying genetic information from DNA to the ribosomes.

Front

What is an anticodon?

Back

An anticodon is a three-base sequence on tRNA that is complementary to a codon on mRNA, allowing for the correct amino acid to be added during translation.

Front

What is the significance of the start codon?

Back

The start codon (AUG) signals the beginning of translation and codes for the amino acid methionine.

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins, linked together by peptide bonds.
