coupled processes
contains hydrophilic heads that are also polar
R group interactions
pol II cant bind without transcriptin factors first
binds to promoter to direct RNA transcription
the head and tail make these matrixes
connected throgh the fact that phospholipids have a hydrophobic tail made up of fatty acids
These two process are to make functional proteins for different function in cell
part of what makes a phospholipid is a fatty acid
they are made by these type of reactions to be able to bind

BIO concept map (erick chungata EJC2828)

Biological molecules

Lupids

fat molecule ( triglycerol)

unsaturated

trans

cis

knk

saturated

no kink

cholesterol

amphipathic

has an OH group

proteins

to identify protein know the R group

R groups can be polar, acidic, basic, or non polar

CH3 non polar

OH, NH, SH, CO are all polar

positive charge makes it positive

acidic is negatively charged

polypeptide

primary structure

secondary structure

tertiary structure

quartenary structure

Subtopic

carboydrates

synthesis of polymers

condestaion reactions

glucose

C6H1206

disaccharides

alpha helicases

beta helicases

Nuleic acid

DNA polymers

DNA polymerase

RNA polymers

RNA polymerase

Nucleotides

have phosphate groups

phosphodiester linkages allow linkage

Organic compounds, water and types of bonds

intercellular matrix

functional groups

hydroxy group

carbonyl group

carboxyl

amino

sulfyhydryl

phosphate

Gene expression

Transcription

Eukaryotic type

happen in the nuclues

how Pre Mrna is formed

transcritption starting is with a template strand

promoter

RNA polymerase

initiation

elongation

termination

Pol II pre Mrna

trnascription factors

Prokaryotic type

happens in the cytoplasm

form MRNA

translation then happens forming amino acids

at the end poly a tail and cap are formed

translation

starts at AUG

Trna

ribosomes

amino acids

peptydal transferase

initiation factors

elongation factors

release factors

mutations

silent

missense

nonsense
