1. RNA: Transcription and Translation

2. Review
What is a nucleic acid?
What does DNA do?

3. Functions to create proteins
What is RNA?
A nucleic acid, like DNA
Functions to create proteins

4. How is RNA different than DNA?
Single stranded

5. How is RNA different than DNA?
Different sugar (ribose)

6. How is RNA different than DNA?
Uracil (U) replaces thymine (T) always
U always pairs with A

7. What is the function of RNA?
Name 1 thing that differs between RNA and DNA

8. Creating proteins
DNA contains all information needed to make a protein, but is unable to actually make protein by itself
RNA acts as the go between, carrying information from DNA into the organelles that create protein

9. “Central Dogma”

10. Kinds of RNA
mRNA – Messenger RNA, carries information from DNA to the ribosome
rRNA – Ribosomal RNA, makes up part of the ribosome
tRNA – Transfer RNA, converts information from mRNA into protein

11. mRNA is copied much like DNA replicates
Transcription
Changing DNA into mRNA
mRNA is copied much like DNA replicates

12. mRNA pairs with a single strand of DNA
DNA strand with “ATCG” produces an mRNA with “UAGC”

13. What does mRNA stand for?
What does mRNA do?
What does tRNA stand for?
What does tRNA do?
What does rRNA stand for?
What does rRNA do?
