What is a protein?
a polymer (collection) of amino acids (monomers).
Under who's direction?
- -the making of proteins!
- -under the direction of mRNA
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
What is the codon and the anticodon of this DNA?
If asked to Translate this codon:
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.
