hydrophilic - ANSWER - polar, "water-loving"
- charged and stable in aqueous environment
hydrophobic - ANSWER - non-polar, "water-fearing"
- uncharged and unstable in aqueous environment
what characteristics does hydrogen bonding give water - ANSWER - allows
for cohesion
- gives fluid-like nature
- dipole (makes good solvent for polar molecules)
amphipathic - ANSWER having both a hydrophilic region and a hydrophobic
region (polar and non-polar region)
3 functions of macromolecules - ANSWER information, structure, storage
eukaryotic cells - ANSWER - multicellular
- membrane bound organelles + nucleus
- larger
eg. plant and animal cells
prokaryotic cells - ANSWER - unicellular
- no membrane bound organelles or nucleus
- smaller
eg. bacteria
Mendel - ANSWER established foundation of genetics by performing
hybridization with pea plants
discovered the laws of inheritance
, what are the laws of inheritance - ANSWER factors that control a feature are
called traits and they come in pairs; singular traits are inherited from each
parent to form offspring
traits in offspring are dominant or recessive
dominant traits - ANSWER are expressed + determine phenotype
recessive traits - ANSWER only show if no dominant trait
1869 Friedrich Miescher - ANSWER Swiss biochemist
isolated material from pus in wounds and used bandages; called it nuclein
nuclein was N + P rich and was thought to be a form of storage
1880's Kossel - ANSWER discovered that nuclein was comprised of proteins
and nucleic acids
isolated nucleic acid bases
1890's-1902 Boveri and Sutton - ANSWER observed segregation during cell
division
concluded that chromosomes contain hereditary information
(was still thought that protein was major factor of DNA)
1909-1919 Levene - ANSWER identified importance of deoxyribose
proposed DNA was made of nucleotides
what 3 things make up a nucleotide - ANSWER 1. nitrogen base (A,C,T,G)
2. pentose sugar
3. phosphate group
3 differences between DNA and RNA - ANSWER 1. Ribose instead of
deoxyribose
- charged and stable in aqueous environment
hydrophobic - ANSWER - non-polar, "water-fearing"
- uncharged and unstable in aqueous environment
