What are codons?

Back

Codons are sequences of three nucleotides in mRNA that correspond to specific amino acids or stop signals during protein synthesis.

Front

What amino acid does the codon GAU correspond to?

Back

The codon GAU corresponds to the amino acid Aspartic acid (ASP).

Front

How many amino acids are coded by the DNA sequence ATC-AGC-GCT-GGC?

Back

The DNA sequence ATC-AGC-GCT-GGC codes for 4 amino acids.

Front

What is the role of tRNA in translation?

Back

tRNA molecules match mRNA codons with their corresponding amino acids using anti-codons.

Front

What are proteins made of?

Back

Proteins are made of chains of amino acids linked together by peptide bonds.

Front

What is an anti-codon?

Back

An anti-codon is a sequence of three nucleotides in tRNA that pairs with a complementary codon in mRNA.

Front

What is the function 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 significance of the start codon?

Back

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

Front

What is a stop codon?

Back

A stop codon is a codon that signals the termination of protein synthesis; examples include UAA, UAG, and UGA.

Front

What is the central dogma of molecular biology?

Back

The central dogma describes the flow of genetic information from DNA to RNA to protein.
