transcription and translation Flashcards
transcription step 1- initiation
RNA polymerase binds to promoter and DNA unwinds at the begining of a gene
transcription step 2- elongation
RNA polymerase attaches mRNA to complimentary sequence of DNA in the 5’ to 3’ direction
transcription step 3- termination
terminator sequence stop transcription process resulting in RNA
translation
going from a nucleic acid to an amino acid
exons
part of mRNA that code for a protein
introns
parts of mRNA that do not code for a protein and need to be cut out before translation
translation step 1- initiation
small and large ribsomal units bind to mRNA at the start condon (AUG)
translation step 2- elongation
tRNA enters large ribosomal unit at the A site and the anticodons of the tRNA bind w the codons of the mRNA
translation step 3- elongation
tRNA shifts to the p site of the large ribosomal unit and the amino acids produced bind together
translation step 4- elongation
tRNA shifts to the E site of the large ribosomal unit and exits the unit
translation step 5- termination
a stop codon is reached in the mRNA, releasing the ribosamal units and polypeptide chain
transcription coding- RNA
C-ar stays in the G-arage
T-ree still has A-pples, but
A-pples are U-nder tree
