What is a gene mutation?

Back

A gene mutation is a change in the nucleotide sequence of DNA or RNA that can lead to changes in the protein produced.

Front

What type of mutation is represented by the change from CGG to CGC?

Back

This is an example of a silent mutation, where the amino acid sequence remains unchanged despite the change in nucleotide sequence.

Front

What is a nonsense mutation?

Back

A nonsense mutation is a type of mutation that results in a premature stop codon in the mRNA sequence, leading to a non-functional protein.

Front

What type of RNA is responsible for protein synthesis and is often referred to as the 'messenger' RNA?

Back

mRNA (messenger RNA) is responsible for carrying the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the role of rRNA in protein synthesis?

Back

rRNA (ribosomal RNA) is a component of ribosomes and plays a crucial role in the translation of mRNA into proteins.

Front

What is the correct pathway for protein synthesis?

Back

The correct pathway for protein synthesis is DNA -> RNA -> Protein.

Front

What is a silent mutation?

Back

A silent mutation is a change in the nucleotide sequence that does not alter the amino acid sequence of the resulting protein.

Front

What is the function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) transports specific amino acids to the ribosome during protein synthesis, matching them to the codons on the mRNA.

Front

What is the significance of the codon chart in genetics?

Back

The codon chart is used to determine which amino acids correspond to specific codons in mRNA, aiding in the translation process.

Front

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

Back

The three main types of RNA involved in protein synthesis are mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).
