Bell Ringer: Name the organelles: Digests waste in the cell Manages the cell Lines up the Spindle Fibers and controls cell division Converts sugar to ATP energy Packages proteins

Joke of the Day:
3
DNA Replication/Transcription/Translation
4
Terms DNA: Deoxyribonucleic acid
5
Terms DNA: Deoxyribonucleic acid Nucleotide: (monomer) Building block of DNA. Consists of Nitrogenous base, phosphate group, and sugar
6
Terms DNA: Deoxyribonucleic acid – Read in groups of 3 nucleotide (bases) called TRIPLET CODE Nucleotide: Building block of DNA. Consists of Nitrogenous base, phosphate group, and sugar 4 nitrogenous bases: – Adenine – Thymine – Guanine – Cytosine
7
Terms DNA: Deoxyribonucleic acid Nucleotide: Building block of DNA. Consists of Nitrogenous base, phosphate group, and sugar 4 nitrogenous bases: Chargraff’s Rule – Adenine A-T – Thymine G-C – Guanine – Cytosine
8
Replication Occurs in the nucleus during S phase of cell cycle.
9
Replication Occurs in the nucleus during S phase of cell cycle. Why? So that each new cell can have an identical copy of DNA after division.
10
Protein Synthesis Transcription: RNA polymerase unzips and reads one side of DNA strand. mRNA is formed. (single stranded) – mRNA: single stranded mirror image of DNA
11
Protein Synthesis Transcription: RNA polymerase unzips and reads one side of DNA strand. mRNA is formed. (single stranded) – mRNA: single stranded mirror image of DNA – Codon: Series of 3 mRNA nucleotides(bases)
12
Protein Synthesis Transcription: DNA polymerase unzips and reads one side of DNA strand. mRNA is formed. (single stranded) – mRNA: single stranded mirror image of DNA – Codon: Series of 3 mRNA nucleotide (bases ) – Uracil: RNA’s version of Thymine (DNA has “T”. RNA has “U”.)
13
Protein Synthesis Translation Decoding of a mRNA message into a polypeptide chain (protein)
14
Protein Synthesis Translation mRNA is read at the ribosome and tRNA is created (single stranded) – Anticodon: series of 3 tRNA nucleotide (bases)
15
Protein Synthesis Translation mRNA is read at the ribosome and tRNA is created (single stranded) – Anticodon: series of 3 tRNA bases – Amino acid: building block of protein (monomer)
16
Protein Synthesis Translation mRNA is read at the ribosome and tRNA is created (single stranded) – Anticodon: series of 3 tRNA nucleotide bases – Amino acid: (monomer) building block of polypeptide – Polypeptide: (protein) chain of amino acids

Protein Synthesis Big Picture

Stem Cells http://www.youtube.com/watch?v=DealmN94tRw&feature=related Unspecialized cells capable of renewing themselves through cell division, sometimes after long periods of inactivity. Potential to develop into many different cell types in the body They serve as a sort of internal repair system, dividing essentially without limit to replenish other cells. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.
