1. How are proteins produced?

2. Warm Up Describe DNA replication in your own words.
Sketch (draw) the process showing unwinding of DNA, splitting of the strands, replication of each strand.
To get 5 pts credit you must be in your assigned seat and working actively when I come by to check.

11. RNA Five differences between RNA and DNA
Sugar in RNA is ribose instead of deoxyribose
RNA is single stranded
RNA contains Uracil instead of Thymine
RNA is disposable
RNA can be outside the nucleus, DNA can’t
If you are going from DNA to RNA – what nitrogenous base would pair with Adenine?
DNA: C A G T T A
RNA: _ _ _ _ _ _

12. ANSWER:
DNA: C A G T T A
RNA: G U C A A U

13. Types of RNA Messenger RNA (mRNA): carry instruction copies
Key players in Protein Synthesis -
Messenger RNA (mRNA): carry instruction copies
Ribosomal RNA (rRNA): makes up ribosome along with proteins
Transfer RNA (tRNA): brings amino acids to the ribosome
