A Nucleotide Consists of what three parts?
 Sugar
 Phosphate
 Base
 Repeating strands of nucleotides make up DNA/
RNA
Chargaff’s Rule for base Bonding
 Cytosine with Guanine
 Thymine with Adenine
 RNA: Thymine is replaced with Uracil
Central Dogma / Use of DNA
 DNA-Transcription-RNA-Translation-Amino Acids
DNA
 GATAGCCGATTACGGATA
 Complimentary Strand
 CTATCGGCTAATGCCTAT
 RNA
 CUAUCGGCUAAUGCCUAU
 A Codon is: Three base pairs: CUA
 Codon = Amino Acid
A mutation is
 A permanent change in DNA
Cell Cycle and Mitosis
IPMATC
Interphase, Prophase, Metaphase, Anaphase,
Telophase, Cytokinesis
Mitosis: PMAT: 1 cell to 2 cells (Identical)
Chromosomes Numbers
 How many chromosomes does a human have? 46
 Diploid / 2N: 46 Chromosomes
 Haploid / N: 23 Chromosomes
Meiosis
 Meiosis I
 PMAT : 1 cell to 2 cells
 Meiosis II
 MATC : 2 cells to 4 cells
 Purpose: Gamete Creation (Sex Cells)
 Maintain Number of Chromosomes
 1 cell to 4 cells (unique)
Mendel Genetics
 Genotype: TT, Tt, tt : Genes
 Phenotype: Tall, Short : Physical expression
 Homozygous: TT, tt
 Heterozygous: Tt
What does it mean for a gene to be dominant
 It overpowers other genes (Recessive)
 Punnett Square on board

Ratios, %, Genotype, Phenotype
Other types of Heredity
 Incomplete Dominance
 RR X rr = Rr
 Red X White = Pink
 Codominance
 BB X bb = Bb
 Black X White = Black and White
 Sex linked trait
 Genes linked to sex chromosomes
 XX= female
XY= Male
 Example Colorblindness
