    Summary

    28/48

    Transcription 1

    (making a mRNA copy of DNA)

    The part of the DNA molecule (the gene) that the cell wants theinformation from to make a protein unwinds to expose the bases.

    Free mRNA nucleotides in the nucleus base pair with one strand of

    the unwound DNA molecule.

  • 5/28/2018 bio part 2

    29/48

    Transcription 2

    The mRNA copy is made with the help of RNA polymerase. This enzyme joins

    up the mRNA nucleotides to make a mRNA strand.

    This mRNA strand is a complementary copy of the DNA (gene)

    The mRNA molecule leaves the nucleus via a nuclear pore into the cytoplasm

    Translation

    RNA

    Single stranded Does not contain thymine but

    has uracil instead.

    tRNA carries 3 base pair codefor specific amino acid.

    Amino acids composepolypeptid chains.

    One or more polypeptidechains compose a protein

    proteins provide the

    blueprints for ourcharacteristics andfunctions.

    In Prokaryotes there are three (3) regulatory elements thatcontrol gene expression.

    1. Structural genes genes that code for a specificpolypeptide (protein).

    2. Promoter DNA segment that recognizes RNA

    polymerase.3. Operator element that serves as a binding site for an

    inhibitor protein that blocks transcription.

    1.

    First the mRNA attaches itself to a ribosome (to the small subunit).

    Six bases of the mRNA are exposed.A complementary tRNA molecule with its attached amino acid (methionine) base pairsvia its anticodon UAC with the AUG on the mRNA in the first position P.

    Another tRNA base pairs with the other three mRNA bases in the ribosome at positionA.

    The enzyme peptidyl transferase forms a peptide bond between the two amino acids.

    The first tRNA (without its amino acid) leaves the ribosome.

  • 5/28/2018 bio part 2

    42/48

    Translation 2

    The ribosome moves along the mRNA to the next codon (three bases).

    The second tRNA molecule moves into position P.

    Another tRNA molecule pairs with the mRNA in position A bringing its amino acid.

    A growing polypeptide is formed in this way until a stop codon is reached.

  • 5/28/2018 bio part 2

    43/48

    End of Translation

    A stop codon on the mRNA is reached and this signals the ribosome to leave the

    mRNA. A newly synthesised protein is now complete!

    6 This process continues until the stop

    codon on the mRNA is reached
