BIO concept map

The process of gene expression involves two main stages: transcription and translation. During transcription, RNA polymerase synthesizes pre-mRNA from a DNA template strand in eukaryotic cells, which occurs in the nucleus, while in prokaryotic cells, it happens in the cytoplasm.

Gene expression

mutations
nonsense
missense
silent
translation
release factors
elongation factors
initiation factors
peptydal transferase
amino acids
ribosomes
Trna
starts at AUG
Transcription
at the end poly a tail and cap are formed
Prokaryotic type

happens in the cytoplasm

form MRNA

translation then happens forming amino acids

Eukaryotic type

happen in the nuclues

how Pre Mrna is formed

trnascription factors

Pol II pre Mrna

transcritption starting is with a template strand

termination

elongation

initiation

promoter

extracellular matrix
amphiphatic molecules
phospholipids
ionic bonds
non polar bonds
hydrohphobic interactions
polar bonds
hydrophilic interaction

Biological molecules

Nuleic acid
Nucleotides

have phosphate groups

phosphodiester linkages allow linkage

RNA polymers

RNA polymerase

DNA polymers

DNA polymerase

carboydrates
beta helicases
alpha helicases
disaccharides
glucose

C6H1206

synthesis of polymers

condestaion reactions

proteins
Subtopic
quartenary structure
tertiary structure
secondary structure
primary structure
polypeptide
R groups can be polar, acidic, basic, or non polar

acidic is negatively charged

positive charge makes it positive

OH, NH, SH, CO are all polar

CH3 non polar

to identify protein know the R group
Lupids
cholesterol

has an OH group

amphipathic

fat molecule ( triglycerol)

saturated

no kink

unsaturated

knk

cis

trans
