Create another strand of DNA Where does it happen? Nucleus (dna is a prisoner) A A A C C G T A C T T T G G C A T G

Create the strand of mRNA from the DNA Where does it happen? Nucleus (still trapped) A A A C C G T A C U U U G G C A U G

rewrite the strand, placing a Guanine where it will cause the greatest impact in the product A A A C C G T A C G U U U 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

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 46

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 no no 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.
