DNA IN ALL LIVING ORGANISMS Friday, November 8, 2013
A DNA nucleotide Consists of: • Ribose sugar, Nitrogen base, Phosphate • Deoxyribose sugar, Gene, Phosphate • Deoxyribose sugar, Nitrogen base, Nucleic Acid • Deoxyribose sugar, Nitrogen base, Phosphate
A gene is made up of a sequence of ________ and is found on a _________ • Chromosomes…Nucleotide • Adenines…Chromosome • Nucleotides…Chromosome • Traits…Nucleotide
Which series is arranged in correct order according to decreasing size of structures? • Nitrogenous Base, Nucleus, Chromosome, Nucleotide, Gene • Nucleotide, Chromosome, Nitrogenous Base, Nucleus, Gene • Nucleus, Chromosome, Gene, Nucleotide, Nitrogenous Base • 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!
A T A T G C G C GENES! A T G C C G C G 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!)
A T A T G C G C GENES! A T G C T A C G DNA of a pecan tree DNA of a human
A T C G T A G C GENES! A T G C T A C G DNA of a streptococcus DNA of a human bacteria
YOUR TURN TO PRACTICE! • Fill out the COMPLIMENTARY DNA strands on each strip! • Cut all the pictures and gene segments apart from one another. • The human DNA strand is: ATG-TAC-AAC-GGA-CAG. Glue this one at the top of your notebook page! • Put the images in order from most to least related to human in your notebooks. • Place the gene segments with the organism that you predict it to belong to, based on what you have learned today. • Once you have had me check, glue them next to each other!
