Study Notes
Blood Type Inheritance
- A man with AB blood and a woman with O blood will have offspring with blood types A or B.
Barr Bodies
- Mammalian cells with a XXXXY chromosomal constitution will have 3 Barr bodies.
Mitochondrial Disease Risk
- If one parent has a mitochondrial disease and the other does not, all children will have a risk of inheriting the disease.
Drosophila Gene Location
- The purple (p) and curved (c) genes in Drosophila are on the same chromosome.
Recombinant Chromosomes
- Recombinant chromosomes in the F1 generation are shown in the diagram.
Meiosis Purpose
- Meiosis in animals produces gametes.
Meiosis and Alleles
- A homologous pair of chromosomes in a bivalent will possess four alleles for each locus in meiosis.
Plant Life Cycle End
- Fertilization ends the multicellular haploid phase of a plant's life cycle.
DNA Strand End Identification
- The 3' end of a DNA strand is identified by a free -OH group on the sugar.
Guanine-Adenine Ratio
- If a species has 22% guanine in its genome, it is expected to have 28% adenine.
DNA Ligase Deficiency
- A deficiency in DNA ligase will result in DNA fragments not linking together correctly.
Telomere Function
- Telomeres are repeating DNA sequences at the end of chromosomes that protect and identify them.
Promoter Region Function
- The promoter region is a DNA region where RNA polymerase binds and initiates transcription.
Spliceosome Composition
- Spliceosomes are composed of snRNPs.
Membrane Component Exclusion
- Nucleic acids are not a component of biological membranes.
Membrane Fluidity Factors
- Saturated fatty acid tails, high temperatures, and shorter fatty acid tails increase membrane fluidity, while cholesterol and double bonds in fatty acids decrease it.
Membrane Transport Inhibition
- Iron (Fe+) cannot directly pass through the membrane due to its charge.
Isotonic Solution Red Blood Cell Response
- Red blood cells placed in a 4% NaCl solution (hypertonic) will shrink (crenate).
tRNA Function
- Anticodon is the part of tRNA that interacts with the codon.
Translation Elongation
- Elongation of translation involves moving a peptidyl-tRNA from the A site to the P site.
Membrane Transport Protein Types
- Antiporters transport two or more molecules in opposite directions across the membrane.
