14. Identify 3 Differences

15. RNA
DNA
Ribose sugar
Single-Stranded
Contains the base Uracil (U) instead of Thymine (T)
Can leave nucleus
Deoxyribose sugar
Double-stranded
Contains the base Thymine (T)
Cannot leave nucleus

16. The protein codes for a gene A gene codes for a trait
DNA codes for a protein
The protein codes for a gene
A gene codes for a trait
Protein Synthesis:
Transcription: DNA to mRNA
Translation: mRNA to protein

17.
What is the blue molecule doing? (3 jobs!)
What is the copy (yellow strand) made of?
In RNA, _______ is replaced with ______.
What is this process called?

18. Why RNA? DNA is used to make proteins.
DNA cannot leave the nucleus so DNA is changed to mRNA (m= messenger RNA)
process is called TRANSCRIPTION
Rule: There is not Thymine (T) in RNA, instead there is Uracil (U)
