protein synthesis questions

[william]

1. what is the piece of genetic information removed from the mRNA molecule strand after translation occurs?

2. what is the molecule that brings amino acids to the ribosome mRNA complex?

3. which amino acid does the dna codon TAC correspond to?

[Russ]

1) Oh wow, I'm really not sure. Possibly something to do with initiation and the ribosomal subunits attaching?

2) tRNA (the "t" stands for "transfer"). If it has an amino acid attached it is generally referred to as "charged".

3) Tyrosine. You should get a codon table in any formal assessment though, it's quite unusual to expect you to memorize it.

we have the choices codon,anti-codon,termination codon, intron,exon

Hmmm. Introns are removed from the mRNA but it happens before translation not after. I'm trying to remember now what exactly happens to termination codons, besides them triggering release factors.
