molecular basis of inheritance
DNA:- In most org.(nucleotide -- monomer) Nucleic acids of two types 1.DNA 2.RNA WHY DNA is more stable? at the place of OH o is removed so,it is not stable. RNA - it has multiple function such as -messenger -mRNA - also have catalytic role or as an adaptive molecule. -mostly in virus. Length = no. of nucleotide/base pair fi * 174 --> 5386 nucleotide since it is a nucleotide it is not forming a base pair lambada ---> 48502 bp E.coli-->4.6*10^6bp. Human -->3.3*10^9bp since they are forming the base pair they are double standards and the first one is singele standard. what is the difference between nucleotide and nucleoside... Nitrogen Base + sugar --->Nucleoside + Phosphate---> Nucleotide purine - aag---A,G aganin and guanine also known as emidiasole pyfimidine - C,T,U---CUT cytocine,uracine and thymine Nucleosides:- Adenosine,guanosine,thymidine,cytidine,uridine. phosphoester 5'---------------3' free OH group
