Lecture 1 Flashcards
gibbs free energy equation
deltaG = deltaH - TdeltaS
non covalent interactions
hydrogen bonds dipole-dipole interactions ionic interactions van der waals forces the hydrophobic effect
do polar or non polar forces interact
polar and polar
non-polar and non-polar interact favourably
non-covalent interactions in water
hydrogen bonds
the hydrophobic effect
what is replication
making more DNA
what is transcription
making mRNA - same language
what is translation
making the protein final product - three letter words
information flow
DNA, messenger RNA, protein
what does uracil replace
thymine
what monomer is DNA and RNA made of
nucleic acid
what monomer is protein made of
amino acids
what do ribonucleotides contain
three phosphate groups
process of transcription
ribonucleotides hydrogen bond through complementary base pairing to exposed deoxyribonucleotides on the unwound DNA
ribonucleotides are covalently bonded together by phosphodiester bonds
the energy is supplied by the cleavage of two phosphates
what direction does RNA polymerase move in
5’ - 3’
define triplet
3 bases (codon) needed to specify an amino acid
