Transcription

process in which part of the nucleotide sequence of DNA is copied into a complementary sequence in RNA

synthesis (making) of RNASlide14

Transcription

during transcription,

RNA polymerase binds to DNA at a promoter (start) site unzipping the DNA double strandSlide15

TranscriptionSlide16

RNA polymerase

enzyme that produces RNA

uses one of the DNA strands as a template from which RNA nucleotides are assembled to make mRNAmRNA = messenger RNATranscription AnimationSlide17

RNA Editing

before the mRNA can leave the nucleus it has to be edited

it receives a cap and a tailintrons are cut out and exons spliced togetherSlide18

RNA Editing

Intron

sequence of DNA that is NOT involved in coding for a proteinExonexpressed sequence of DNA that codes for a proteinSlide19

RNA EditingSlide20

3 types of RNA

mRNA = messenger RNA

carries message from DNA in the nucleus into cytoplasm where ribosomes are locatedSlide21

3 types of RNA

tRNA

= transfer RNAconnects amino acids to protein chainSlide22

3 types of RNA

rRNA

= ribosomal RNAmakes up a portion of a ribosomeSlide23

DNA after Transcription

after

transcription of RNA is complete, the strands of the DNA double helix hydrogen bond back together at the nitrogen basesallows DNA to remain unchanged and used for the transcription of additional RNA moleculesSlide24

R

NA after Transcription

after mRNA is edited, it leaves the nucleusSlide25

R

NA after Transcription

once it gets to the ribosome, it will help make a proteinSlide26

Think, Pair, Share…Slide27

1. Is the RNA strand below copied from the DNA strand on the left or the DNA strand on the right?

2. How do you know?Slide28

1. The RNA is made from the strand on the

LEFT.

2. RNA is transcribed complementary.Slide29

Summary

Transcribe the template DNA strand on the

right into a single stranded piece of mRNA.
