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
