DNA, RNA, and Protein Synthesis

Front

What is a codon?

Back

A codon is a group of three bases (ex. AUG) that codes for a specific amino acid.

Front

What does a nucleotide of DNA NOT contain?

Back

A nucleotide of DNA does NOT contain an amino acid.

Front

How are amino acids transferred to ribosomes?

Back

Amino acids are transferred to ribosomes by tRNA (transfer RNA).

Front

What does a nucleotide contain?

Back

A nucleotide contains a phosphate group, a sugar, and a nitrogenous base.

Front

What is true about RNA structure?

Back

RNA is usually single-stranded.

Front

What are the components of a nucleotide?

Back

A nucleotide consists of a deoxyribose sugar, a phosphate group, and a nitrogenous base.

Front

What is the role of mRNA in protein synthesis?

Back

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

Front

What is the function of tRNA?

Back

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

Front

What are the nitrogenous bases found in DNA?

Back

The nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What are the nitrogenous bases found in RNA?

Back

The nitrogenous bases in RNA are adenine (A), uracil (U), cytosine (C), and guanine (G).
