DNA Central Dogma

What is the purpose of transcription?

• Transferring amino acids to the ribosome.

• Producing more nucleotides for the DNA sequence.

• Producing a mRNA from information found in the DNA.

Which of the following units are repeatedly joined together to form a strand of DNA?

• amino acids

• nucleotides

• fatty acids

• polysaccharides

Transcription takes place in the 

• cytoplasm

• ribosome

• mitochondrion

• nucleus

The anticodon of a particular tRNA molecule is 

• complementary to the corresponding mRNA codon.

• complementary to the corresponding triplet in rRNA.

• the part of tRNA that bonds with a specific amino acid.

• catalytic, making the tRNA a ribozyme.
