1 RNA and Transcription DNA RNA PROTEIN

2 RNA and Transcription

3 RNA Ribonucleic Acid another type of nucleic acid found in cells –also made of nucleotides takes information from the nucleus to the rest of the cell

4 DNA-RNA Comparison Chart DNARNA sugar bases strands found

5 DNARNA sugarDeoxyribose bases strands found DNA-RNA Comparison Chart

6 DNARNA sugarDeoxyriboseRibose bases strands found DNA-RNA Comparison Chart

7 DNARNA sugarDeoxyriboseRibose bases Adenine, cytosine, guanine, thymine Adenine, cytosine, guanine, strands found DNA-RNA Comparison Chart

8 DNARNA sugarDeoxyriboseRibose bases Adenine, cytosine, guanine, thymine Adenine, cytosine, guanine, uracil strands found DNA-RNA Comparison Chart

9 DNARNA sugarDeoxyriboseRibose bases Adenine, cytosine, guanine, thymine Adenine, cytosine, guanine, uracil strandsdouble (2) found DNA-RNA Comparison Chart

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

14 Transcription during transcription, RNA polymerase binds to DNA at a promoter (start) site unzipping the DNA double strand

15 Transcription

16 RNA polymerase enzyme that produces RNA uses one of the DNA strands as a template from which RNA nucleotides are assembled to make mRNA –mRNA = messenger RNA Transcription Animation

17 RNA Editing before the mRNA can leave the nucleus it has to be edited –it receives a cap and a tail –introns are cut out and exons spliced together

18 RNA Editing Intron –sequence of DNA that is NOT involved in coding for a protein Exon –expressed sequence of DNA that codes for a protein

19 RNA Editing

20 3 types of RNA

21 mRNA =

22 3 types of RNA mRNA = messenger RNA

23 3 types of RNA mRNA = messenger RNA tRNA =

24 3 types of RNA mRNA = messenger RNA tRNA = transfer RNA

25 3 types of RNA mRNA = messenger RNA tRNA = transfer RNA rRNA =

26 3 types of RNA mRNA = messenger RNA tRNA = transfer RNA rRNA = ribosomal RNA

27 3 types of RNA mRNA = messenger RNA tRNA = transfer RNA rRNA = ribosomal RNA
