RNA and Codons

What does tRNA do during translation?

• it brings a specific segment of DNA to the ribosome for transcription

• it brings any amino acid to the ribosome

• it brings a specific amino acid (decided by the DNA) to the ribosome for translation

• it brings a specific amino acid (decided by the codon) to the ribosome for translation

What is made during transcription?

• DNA

• RNA

• Proteins

• Amino Acids

Codons are located on....

• DNA

• mRNA

• tRNA

• rRNA

Anti-codons are located on...

• DNA

• mRNA

• tRNA

• rRNA

What amino acid is added to the protein when the mRNA has the codon AUG?

• Phenylalanine

• Methionine

• Leucine

• Stop codon

The "language" of mRNA is called the ​ (a)   , and it uses three-letter "words" called ​ (b)  

• genetic code

• codons

• nucleotide strategy

• anti-codons

• amino acids

Answer explanation

The 'language' of mRNA is referred to as the genetic code, and it uses three-letter 'words' called codons to encode specific amino acids during protein synthesis.
