Put levels of organization in order, with pictures • DNA, cell, gene, nucleus, chromosome,
cell nucleus chromosome gene DNA
Create another strand of DNA • Where does it happen? • Nucleus (dna is a prisoner) • A AA C C G T A C • T TT G G C A T G
Create the strand of mRNA from the DNA • Where does it happen? • Nucleus (still trapped) • A AA C C G T A C • U UU G G C A U G
rewrite the strand, placing a Guanine where it will cause the greatest impact in the product • A AA C C G T A C • G U UU G G C A U
mRNA is a code for amino acids, • which are linked together in the cell organelle ribosome, • to create proteins
5 uses for proteins in your body (add the rest to your answer) • Create muscle, bone and skin cells • Enzymes • Antibodies • Hormones • Cell membranes
What does DNA have to do with protein creation? • Contains code for amino acids, so protein will be made
Mitosis • Type of cell • Body cell • # chromosomes that start process • 2n • # chromosomes in cell that is created • 2n • Diploid or haploid • diploid
Mitosis • sketch 46 46 46 92 46
Meiosis • Type of cell • Gamete (or…..) • Reproductive cell • # chromosomes that start process • n • # chromosomes in cell that is created • n • Diploid or haploid • haploid
meiosis • sketch 23 46 46 23
3 causes of mutations • radiation (tanning beds, xrays) • Chemicals (mercury, benzene) • Unknown
What type of cell would a mutation have greatest affect on next generation? • Arm or eye or stomach or…… no nono • Gamete ; because you reproduce with them, which is passing trait to next generation
DNA • Building block is • Sugars, phosphates and nitrogen bases • One function • Code for proteins
Protein • Building block is • Amino acids • One function • Enzymes, etc.
Carbs • Building block is • Sugars (monosaccharide or glucose), • One function • Energy (ATP)
Fats • Building block is • lipids • One function • Insulation, energy
Make sure you know answers to Down’s syndrome essay in Reebop • Unit exam on Monday, unless you have lots and lots of good questions for me on Monday…. Then test will be Tuesday.
