Unformatted text preview: DNA backbone Nucleoside Nitrogenous base + ribose sugar Combines with different numbers of phosphates to form different level of energy molecules like NMP, NTP, ATP. Nucleotide Nitrogenous base+ ribose sugar + Phosphate Serves as energy storage molecules, signal molecules, & units of hereditary materials. DNA Amino Acids with various functional groups like acids, amides, alcohols, and amines, as side chains. i) Usually double helix with 2 strands running in opposite directions,ii) Each strand is polymer of nucleotide subunits. iii) each strand has deoxyribose backbone linked together by phosphate group iv) Inside the double helix A:T & G :C(H-bond) pairing takes place.v) DNA 5' end terminates in a phosphate group and the 3'end contains a hydroxyl group. Stores genetic information in its sequence and codes for RNA PB RNA i) Mostly present as single stranded molecule, each strand is polymer of nucleotide subunitsi) each strand has ribose backbone linked together by phosphate group iii)when it is double stranded complementary base pairing takes place,A: U(not T) and G: C.iv)RNA 5'end terminates in a phosphate group and the3'end terminates in a sugar molecule mRNA:carries information from DNA to protein. rRNA: major part of ribosome involved in protein synthesis tRNA: transfers amino acids during protein synthesis PB...
