How to trace cell lineages
Direct Observation of embryo
Dye marking
Genetic labbeling
Genetic labbeling
permanent labbeling of cells and their progressors
Chimera
Individual containing cells from two different species
Genomic equivalence
Each somatic cell nucleus within an organism has identical chromosomes and same set of genes
nucleosomes can be wound into tight
solenoids
Heterochromation
Chromatin mainly in solenoid conformation, low transcription rate
Acetylation
compensates positive charge of lysines and loosens nucleosomes
activation of transcription
Methylation
can repress or activate
mainly repress
Enhancer
DNA sequence which controls efficency and rate of transcription
binds transcription factors
Can control temporal and tissue specific expression of genesEnhancers are cis regulatory elements
only activate Promotor on same chromosome
Transcription factor domains
DNA binding domain
Trans activation domain
Protein-protein interaction domain
Tracing of cell lineages is used to create
fate maps
