proteom - whole protein in all living things

Nitrog­enous Base	Sugar Moiety
Pyrimidine	2-Deox­yribose
Cytosine	Ribose
Uracil
Thymine
Purine
Adenine
Guanine

DNA is long polymer of nucleo­tides

Phosph­odi­ester linkage between 3' and 5'

Hbond of nitrog­enous base

Anti-P­arallel

Nucleosome	-Funda­mental Unit
	-(+) Histone and (-) DNA
Histone	-present in quantities that their total mass in chromatin
	-high proportion of positively charged AA

Arrang­ement
Nucleosome	-basic structural unit of chromatin
Chromatin Fiber	-coiled and condensed to form chromo­somes
Loops	-chromatin fiber folded into loops
Chromosome	-H2A, H2B, H3,H4

A= T	Apple in Tree
C = G	Car in Garage

DNA	RNA
Adenine , Thymine	Adenine , Uracil
Cytosine , Guanine	Guanine , Cytosine

mRNA	-messenger RNA -premature, code for proteins -blueprint
rRNA	-ribosomal RNA -most abundant , basic structure of ribosome
tRNA	-transfer RNAs -adaptor between mRNA and AA
snRNA	-small nuclear RNA -spilicing of pre-mRNA
snoRNA	-small nucleolar RNA -modify rRNA
other noncoding RNA	-e.g. telemore synthesis -X chromosome inactivation -transport of proteins into ER
