From DNA to Protein

Front

What is a point mutation?

Back

A point mutation is a change in a single nucleotide in the DNA sequence, which can lead to changes in the protein produced.

Front

Where does translation occur in eukaryotic cells?

Back

Translation occurs at the ribosomes in the cytoplasm.

Front

What base does RNA contain that DNA does not?

Back

RNA contains uracil (U), while DNA contains thymine (T).

Front

What do most codons specify?

Back

Most codons specify an amino acid.

Front

Why is DNA important?

Back

DNA contains the hereditary information and instructions for making proteins.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites where translation occurs, synthesizing proteins from amino acids based on mRNA sequences.

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.

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosomes for protein synthesis.

Front

What is a codon?

Back

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

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.
