3
3 of 21
RNA polymerase ll
most protein transcripts
4 of 21
RNA polymerase l
most rRNA
5 of 21
RNA polymerase lll
most tRNA transcripts
6 of 21
Differential splicing
generates variant mRNA sequences from a single gene
7 of 21
Polytene
multiple DNA copies of the same chromosome bunched up
8 of 21
Translation allows
protein synthesis, conserved genetic code,tRNA coupled to specific amino acid, activation of amino acids with ATP
9 of 21
Outline of transcription
DNA in nucleus, mRNA copy made using template strand, mRNA leaves nucleus, goes to a ribosome
10 of 21
Outline of translation
mRNA attaches to ribosome, tRNA bring amino acids to ribsome, amino acid chain is created depending on the mRNA code, sequence of amino acid same as template strand

what is the start codon
AUG
17 of 21
what does universal mean
codons are the same for every organism
18 of 21
what does non-overlapping mean
Each base is only used in one code
19 of 21
what does degenerate mean
The same amino acids can be produced from different codons
