A 2n=6 germline cell completes meiosis I. Each daughter cell - contains three chromosomes, each composed of two sister chromatids. A carcinogen is a chemical or treatment that - causes mutations that can affect gene activity. A deletion occurs during DNA replication, causing the guanine shown in red to be removed from the nucleotide strand. What effect is this most likely to have on the final protein? - The deletion of the G will cause a frame shift, resulting in a premature stop codon and ...

Griffiths (1928) mixed heat-killed 'S' bacteria with 'R' bacteria and injected a mouse with both types of bacteria. As a result, the mouse died and Griffiths obtained living 'S' bacteria from the dead mouse. How can you explain this phenomenon? The DNA from the 'S' bacteria with the gene responsible for capsule formation was transferred to the 'R' bacteria when the strains were mixed. This gene transformed the 'R' bacteria into 'S' bacteria, allowing it to produce a capsule and eva...

10) The nucleus of an atom consist of _________? - Protons, neutrons 11) Carbon can form - All of the bonds (all the above, 4 bonds) 12) What are the monomers of proteins? - Amino acids 13) What are the monomers of a fat? - Fatty acids and glycerol 14) What about nucleic acids? - Nucleotides 15) What is incorrect? - Isotopes of an element are atoms that differ in the numbers of protons 16) Difference between DNA and RNA? - DNA contains a different sugar from RNA and base pairs 17) All liv...

Describe the chemical composition of biological membranes? Biological membranes are bilayers of phospholipids with associated proteins and carbohydrates. What can never be energetically favorable in a biological membrane and therefore will not occur spontaneously? the flip-flop of phospholipids to the opposite leaflet Let's suppose an insect, which doesn't maintain a constant body temperature, was exposed to a shift in temperature from 60°F to 80°F. Which of the following types of membrane...

What kind of cell does Meiosis produce? Daughter cells that are not genetically identical to each other or the parent cell (gamete cells) Cytogenics A field of genetics involving microscopic examination of chromosomes and cell division When are chromosomes visible? During cell division b/c they become very compact What is Karyotype? Reveals the number, size and form of chromosomes in an actively dividing cell. What kind of cell does Mitosis produce? Daughter cells that are identical to each ...

cellular respiration A process by which living cells obtain energy form organic molecules in the presence of oxygen and release waste products. aerobic respiration A type of cellular respiration in which O2 is consumed and CO2 is released. Glycolysis A metabolic pathway that breaks down glucose to pyruvate. breakdown of pyruvate The two pyruvate molecules enter the mitochondrial matrix, where each one is broken down to an acetyl group (with two carbons each) and one CO2 molecule. For each pyr...
