BIOL 112 Lecture 8: cells

Cells have a nucleus, microtubules, actin and a cell membrane. Estimation at 4 x 1013 cells (and there is about same number of bacterial cells) Because

BIOL 112 Lecture 9: cells 2

Lecture 9: cells 2: each protein has a short stretch (unique sequence) of amino acids (also called a tag ). Proteins are tagged: and that tells the gol

BIOL 112 Lecture 10: Glycolysis

The tight junction ensure that materials don"t cross the epithelium. The gap junctions connect two epithelial cells. It creates channels between two ce

BIOL 112 Lecture Notes - Lecture 11: Redox, Reduction Potential, Fumaric Acid

It takes place in the cytoplasm and ends up with pyruvate. The pyruvate then gets shut off in the mitochondria where it is further oxidized to acetyl c

BIOL 112 Lecture Notes - Lecture 13: Thylakoid, Carbon Fixation, Redox

That is exactly the reverse for that of respiration: C6h12o6 + 6 o2 6 co2 + 6 h2o. The photosynthesis reaction takes place in the chloroplast (make the

BIOL 112 Lecture Notes - Lecture 14: Cell Membrane, Cell Theory, S Phase

The ancient greeks figured that males and females must share some essence that mixes to produce the progeny. But they had no idea what that essence mig

BIOL 112 Lecture Notes - Lecture 15: Hydroxycarbamide, Sister Chromatids, G1 Phase

Cell divide themselves with the fact that their daughter cells need to have a good inheritance with exactly the good number of chromosomes. (1 of each

BIOL 112 Lecture Notes - Lecture 16: Pea, Wrinkle, Probability Distribution

Heredity: children resemble their parents, siblings are not identical. Nb: characters are different qualities like hair color, height and each of those

BIOL 112 Lecture Notes - Lecture 19: Homologous Chromosome, Punnett Square, Y Chromosome

BIOL 112 Lecture Notes - Lecture 20: Chromosome, Gene, Mendelian Inheritance

The genes for different traits are lined up along the chromosomes. By having many genes and alleles determine each phenotype. Most of the traits that w

BIOL 112 Lecture Notes - Lecture 21: Semiconservative Replication, Heavy Strand, Nitrogenous Base

Meselson and stahl experiment aims to show how dna was replicated. So, they decided to use an isotope f nitrogen to distinguish between parent and new

BIOL 112 Lecture Notes - Lecture 22: Aminoacyl-Trna, Phenyl Group, Transfer Rna

Lecture 21: more tales of the central dogma. Recap of last lecture: the genetic code is this mapping of triplet codons in the dna (sequences of 3 nucle

BIOL 112 Lecture Notes - Lecture 23: Tobacco Mosaic Virus, Double-Stranded Rna Viruses, Chamberland Filter

Viruses were discovered relatively recently as an infectious agent that is smaller than bacteria. Dmitri ivanosvsky started working on tobacco mosaic v

BIOL 112 Lecture Notes - Lecture 24: Trp Operon, Lac Repressor, Lac Operon

Bacteria can regulate the expression of their genes. Bacteria have the same genes, but if we look at individual bacteria or even a colony of bacteria a
