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.
