Protein Synthesis

Multiple Choice

In DNA, adenine pairs with

• Guanine

• Thymine

• Cytosine

Multiple Choice

In DNA, guanine pairs with

• Adenine

• Thymine

• Cytosine

RNA

• RNA is slightly different from DNA.

• RNA is single stranded.

• It also has 4 bases.

  • Like DNA, RNA has adenine, cytosine, and guanine.

  • Instead of thymine RNA has uracil (pairs with adenine)

• RNA can leave the nucleus.

DNA must open up to make RNA. RNA then pairs matching nucleotides to the DNA.

This makes mRNA. Which is messenger RNA.

Multiple Choice

To make RNA, adenine pairs with

• Thymine

• Guanine

• Cytosine

• Uracil

• mRNA leaves the nucleus and travels to a ribosome.

• Inside the ribosome, mRNA is matched in three letter segments with matching tRNA(transfer RNA).

• The three letter segments are called codons.

• Each codon represents a specific amino acid, which is attached to the tRNA.

• The amino acids attach together to make a peptide chain.
