Homework:

.13.1 and 13.2 notes due wednesday

.Tribute article due next monday

Today in class we started out with an open note quiz on 12.2 and 12.3 notes and in class notes we have been taking during class. After the quiz we went over it and were given the answers. Then Mr. Paek splatter DNA on Quinn's desk and he called it boogers.

The DNA came from a lab we were supposed to do last week but Mr. Peak forgot so we didn't get to see it happen.

Class Notes:

.DNA polymerase (unzips) the DNA strand to replicate the DNA

.Once the DNA is split a copy is added to form two new DNA strands

.DNA becomes RNA so that it can fit through the necleus membrane

DNA compared to RNA:

RNA DNA

1. Has ribose sugar 1.Has deoxyribose

2.Single stranded 2.Double stranded

3.Contains Vracil 3.Contains thymine

Types of DNA

.mRNA-Messenger RNA produced in nucleus then travels to cytoplasm

.rRNA-Makes up ribosome

.tRNA-Transfers RNA and carries amino acids

That is all for todays scribepost thank and come again. Also watch out for Mr. Paek he is flinging DNA all over the place.
