Exam 3 quiz 1 Flashcards
microbial growth
increase in number of cells, how one cell becomes two
generation time/doubling time
time it takes to get from one cell to two cells
DNA replication
replicate chromosomes
Cell elongation
grow cell size
septum formation
beginning of seperation
chromosome replication and partitioning occurs
-all occurs at the very beginning of replication assuming from the start that they should be nicely regulated
caulobacter
-stalked bacteria
-typically in soiled environments
-uses a partitioning system called a par system
par system
-at replication initiation
-anchoring of the parent chromosome
Pop Z
-anchor
-proteins localized to the stalked pole
Par B
-finds chromosome
-bind to Par S sequence within the original chromosome
-once bound Par B can bind to Pop Z
where does replication occur
where Par B can find another Par S sequence
what drives the new chromosome to the other pole
Par A
Par A function
-ATPase motor protein
-binds to other end of Par B/Par S and binds to the other pole
name for the center between the two linked chromosomes
-structural maintenance of chromosome complex
-used to unlink the chromosomes
topoisomerase IV
unlinks
