Front

What is a nucleotide?

Back

A nucleotide is the basic building block of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What causes Translation to terminate?

Back

Translation terminates when a stop codon is reached.

Front

What are the phases of Interphase?

Back

Interphase consists of three phases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

Front

Replicate the following DNA sequence: TAC GGA CCG TAA

Back

ATG CCT GGC ATT

Front

What is the role of tRNA in translation?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during protein synthesis.

Front

Define a codon.

Back

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

Front

What is the function of ribosomes?

Back

Ribosomes are the cellular machinery that synthesizes proteins by translating mRNA into amino acid sequences.

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 is a stop codon?

Back

A stop codon is a nucleotide triplet that signals the termination of protein synthesis.
