La Clase de Biologia ;)

Agenda:

Hand in UP 7-14

Review

Genome Movie

Today in biology, we first handed in UP 7-14 (which was the homework...). The pages were coloring in DNA, and the process in which DNA replicates. The homework was also to finish the questions on the back of those worksheets, and to finish the lab.

Later, we took review notes on DNA and Chromosomes. Let me refresh you on some things.

DNA stands for Deoxyribonucleic Acid.

Nucleotides are the building blocks/ subunits of DNA

~Made of;

-Sugar [deoxyribose]

-Nitrogen Base

-Phosphate Group

Nitrogen Bases:

~Purines-- have 2 rings

-Guanine and Adenine

~Pyrimidines-- have 1 ring

-Thymine and Cytosine

Base Pairing:

-Adenine-Thymine

-Guanine-Cytosine

^ORDER CODES TO MAKE PROTEINS!!!!!

Okay now that we're done with the review... let's go to today's notes!

DNA Replication:

-Replicates during S phase of Interphase

***MITOSIS REQUIRES 2 STRANDS OF GENETIC MATERIAL!!!***

-Each strand serves as a template for the new strand

-Results in 2 identical DNA molecules

-SEMI-CONSERVATIVE REPLICATION- each new molecule contains 1 old strand, and 1 new strand.

I apologize, but my computer isn't working and won't let me post pictures.
