DNA, Protein Synthesis & Mutations Review

Front

What is a codon?

Back

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

Front

What is the complementary DNA strand for the sequence TCG ATA CGA?

Back

The complementary DNA strand is AGC TAT GCT.

Front

Where does translation occur in the cell?

Back

Translation occurs in the ribosome.

Front

What is the second step of protein synthesis?

Back

The second step of protein synthesis is Translation.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is transcription?

Back

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

Front

What is the function of ribosomes?

Back

Ribosomes are the cellular structures where protein synthesis occurs.

Front

What is a mutation?

Back

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

Front

What are the types of mutations?

Back

The main types of mutations are point mutations, insertions, deletions, and frameshift mutations.

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.
