are the segments of DNA carrying instructions for polypeptide chain
the genetic information in the mRNA is translated into a specific protein encoded by the gene
a region of DNA which codes for a single protein or polypeptide
produces an mRNA copy of the gene
transcription of DNA
carries message to nucleus to ribosomes
a necessary DNA sequence that specifies the position of transcriptional initiation (on/off switch)
coding region or transcription unit
sequence of DNA "downstream" of promoter that encodes polypeptide
to make RNA oug of a DNA templet
enhancers that gets everything together and ready
after the _____ the DNA starts transcribing
RNA polymerize ____DNA and makes RNA templet and then______ the DNA. This is called what?
winds back up
when the RNA polymerase reaches its stopping point
now there is an mRNA ready to be released
before the mRNA can be released what must happen?
introns and exons must be taken out
what do RNA codons do?
they code for amino acids according to a "universal" genetic code

if the mRNA foes to rough ER they will____ the cell
where rRNA is made
proof reads amino acids
moves the transitional machinery as polypeptides is being synthesized
help tRNA match base pairing
