  • N2 base + pentose sugar = Nucleoside + phosphate = Nucleotide
  • Higher Nucleotides in face State (2nd & 3nd release 8 kcal/mol on hydrolysis)
  • NAD = Universal hydrogen acceptor.
  • RNA = produced in nucleus stored in nucleolus moves out in cytoplasm
  • Extra nuclear DNA chloroplast & mitochondria
  • Pyrimidine՚s in DNA – 5 methyl cytosine – wheat germ, thymus
  • Pyrimidine՚s in DNA – 5 hydroxyl methyl cytosine – Teven E. coli
  • X ray diffraction of DNA – wilking, franklin, Asturby
  • On heating – 2 strands of DNA uncoil & denature
  • On cooling – 2 strands of DNA together – annealing/renaturation
  • Z – DNA – Zigzag sequence, dinucleotide, left handed double helical Wang, Rich (1979) – CGCGCG sequences, 12 base pair (pro & eukaryote) – gene recombination
  • A DNA will be shorter & have greater diameter then B - form
  • High degree of stability of DNA helix – large no of H2 bond between base pair, right-handed to left handed helix.
  • V. Sasisekharan – RL model – B – DNA has alternating right & left fragment = conformation flexibility
  • Ds RNA = Reovirus/Rice Dwarf virus.
  • M – RAN – Jacob & monad – synthesis of protein
  • R- RAN – largest RAN – protein synthesis
  • T – RAN – Clover lead like structure
  • Ni – urease
  • Mo – dinitrogenase
  • DNA – percentage of C = 18 percentage of A = ? Solving this question we have, and then , so we can say that and
  • Bright field microscopy – bright light & object appears dark
  • Compound microscope – 2 lenses (1) objective (2) eyepiece (ocular)
  • 100 X = highest power = oil immersion lens (abbe)
  • = 39 degree in high power objective
  • Resolving power =
