Friday, November 8, 2013 DNA IN ALL LIVING ORGANISMS

A DNA NUCLEOTIDE CONSISTS OF: A.Ribose sugar, Nitrogen base, Phosphate B.Deoxyribose sugar, Gene, Phosphate C.Deoxyribose sugar, Nitrogen base, Nucleic Acid D.Deoxyribose sugar, Nitrogen base, Phosphate

A GENE IS MADE UP OF A SEQUENCE OF ________ AND IS FOUND ON A _________ A.Chromosomes…Nucleotide B.Adenines…Chromosome C.Nucleotides…Chromosome D.Traits…Nucleotide

WHICH SERIES IS ARRANGED IN CORRECT ORDER ACCORDING TO DECREASING SIZE OF STRUCTURES? A.Nitrogenous Base, Nucleus, Chromosome, Nucleotide, Gene B.Nucleotide, Chromosome, Nitrogenous Base, Nucleus, Gene C.Nucleus, Chromosome, Gene, Nucleotide, Nitrogenous Base D.Chromosome, Nucleus, Nitrogenous Base, Nucleotide, DNA

THE DNA POLYMER… Think back to BIOMOLECULES. All living things are made of BIOMOLECULES! (carbohydrates, lipids, proteins and nucleic acids) All living things must be made of GENETIC MATERIAL in order to reproduce. SO ALL LIVNG THINGS HAVE DNA!

The components that make up the genetic code are common to all organisms! Same NUCLEOTIDES, same BACKBONE same BASE-PAIRS, same HYDROGEN BONDS!

The instructions for making proteins (and traits) are in the sequence of nucleotides! These are the GENES that hold our similarities or differences!

GC TA G A GC C T T G G A C C DNA of a mouse DNA of a human Information for everything about an organism is carried in the order of bases in their DNA, like a language. The more alike two organisms are, the more alike their order of bases will be (because they will have similar traits!) GENES!

GC TA G A GC C T T G A A T C DNA of a pecan tree DNA of a human GENES!

TA GC G A GC C T T G A A T C DNA of a streptococcus DNA of a human bacteria GENES!

YOUR TURN TO PRACTICE! 1.Fill out the COMPLIMENTARY DNA strands on each strip! 2.Cut all the pictures and gene segments apart from one another. 3.The human DNA strand is: ATG-TAC-AAC-GGA-CAG. Glue this one at the top of your notebook page! 4.Put the images in order from most to least related to human in your notebooks. 5.Place the gene segments with the organism that you predict it to belong to, based on what you have learned today. 6.Once you have had me check, glue them next to each other!

EXIT TICKET WRITING ASSIGNMENT: Complete the writing assignment using ABC method! This will be turned in on your way out the door!
