N₂ base + pentose sugar = Nucleoside + phosphate = Nucleotide
Higher Nucleotides in face State (2^nd & 3^nd 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 =
