Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in the structure and function of proteins.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosomes, where proteins are synthesized.

Front

What is the function of ribosomes?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating mRNA into amino acid sequences.

Front

What is tRNA and its role in translation?

Back

tRNA (transfer RNA) brings amino acids from the cytoplasm to the ribosomes during protein synthesis.

Front

Define codon.

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.

Front

What is the difference between DNA and RNA?

Back

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

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into mRNA.

Front

What is translation?

Back

Translation is the process of decoding mRNA to synthesize proteins at the ribosome.

Front

What are the three types of RNA involved in protein synthesis?

Back

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

Front

What is a substitution mutation?

Back

A substitution mutation is a type of mutation where one nucleotide is replaced by another, potentially altering the protein produced.
