-
What is a protein?
a polymer (collection) of amino acids (monomers).
-
What's Translation?
Under who's direction?
Where?
- -the making of proteins!
- -under the direction of mRNA
- -Ribosome
-
1st step of Translation?
mRNA leaves, goes to the ribosome and bonds to rRNA
-
2nd step of Translation?
- tRNA brings in the right amino acid based on complementarity.
- Each tRNA carries a specific amino acid.
-
What is a codon?
What is an anticodon?
- -codon: 3 nitrogenous bases on mRNA
- -anticodon: nitrogenous bases on tRNA
-
What codon is the "start signal"?
What type of amino acid is it?
-
3rd step of Translation?
- the tRNA comes in, the amino acid from tRNA is transferred to the next tRNA.
- as the mRNA moves through the robosome, the tRNA leave the ribosome to get another amino acid from the cytoplasm.
-
4th step of Translation?
process continues until a "stop codon" is reached. mRNA separates from the ribosome.
-
what are the "stop codons"
UAA, UAG, UGA
-
example:
What is the codon and the anticodon of this DNA?
ATC-GCA-TGC-AAT
codon: UAG-CGU-ACG-UUA
anticodon: AUC-GCA-UGC-AAU
-
If asked to Translate this codon:
CCA-GAU-AUG-CUC-GAU
what do you do first? 2nd?
- 1.)START with AUG. (forget the first two)
- if asked to transCRIBE...then include the first two.
- 2.) since it's mRNA, either choose to do DNA or tRNA first.
