RNA Transcription and Translation

A sequence of three nitrogenous bases in the mRNA that give instructions for an amino acid is called a/an:

• codon

• anticodon

• genetic code

RNA that transports copies of the DNA instructions to assemble amino acids and form proteins.

• mRNA

• tRNA

• rRNA

RNA that combines with proteins to form ribosomes.

• rRNA

• mRNA

• tRNA

______________________ is the synthesis of an RNA molecule based on the DNA.

• transcription

• translation

• replication

____________________ is the process where the sequence of bases in the mRNA results in the amino acid sequence of a protein.

• translation

• replication

• translation

RNA that transports each amino acid to a ribosome.

• tRNA

• mRNA

• rRNA

RNA is a double-stranded nucleic acid, just like DNA.
