Term
|
Definition
| one cell gives rise to 2 genetically identical descendants that perform different roles and must therefore express different genes |
|
|
Term
|
Definition
| example of gram positive bacteria that undergoes sporulation in response to adverse growth conditions |
|
|
Term
|
Definition
spores formed inside a mother cell
requires cell to divide asymmetrically |
|
|
Term
|
Definition
when highly phosphorylated, sporulation starts
controls expression of genes including SpoIIE which remove phosphate from SpoIIA |
|
|
Term
|
Definition
| removes phosphate from SpoIIAA |
|
|
Term
|
Definition
| removes anti-sigma factor SpoIIAB and liberates sigma factor F |
|
|
Term
|
Definition
|
|
Term
|
Definition
| starts cascade of 3 sigma factors that are involved in the mother cell and forming endospore |
|
|
Term
|
Definition
| what prevents a cell from cannibalism when lysis of nearby cells of the same species occur for nutrients? |
|
|
Term
|
Definition
| member of Proteobacteria, commonly found in nutrient poor aquatic environments, undergoes differentiation |
|
|
Term
|
Definition
free swimming cells that move via flagella and function in dispersal
cannot divide or replicate DNA |
|
|
Term
|
Definition
lack flagella and are attached to a surface via a stalk with a holdfast
reproductive stage |
|
|
Term
|
Definition
|
|
Term
|
Definition
| present during DNA replication and stalked stage while it is forming swarmer |
|
|
Term
|
Definition
cell fate determinant
if phosphorylated- remains stalked
if not phosphorylated- swarmer |
|
|
Term
|
Definition
| RNA molecules that are not translated into proteins, including rRNA and tRNA |
|
|
Term
|
Definition
small RNAs with complementary sequences to the coding sense of their mRNA
once bound to mRNA, the dsRNA cannot be translated --> are degraded |
|
|
Term
| cis-encoded antisense RNAs |
|
Definition
| antisense RNA that originates by convergent transcription form the same genetic locus as the target RNA |
|
|
Term
trans-encoded antisense RNAs
AKA riboregulators |
|
Definition
| antisense RNA encoded at loci other than those of their target genes |
|
|
Term
|
Definition
| protein that binds to RNA molecules and ribonuclease E often leading to mRNA degradation |
|
|
Term
|
Definition
help sRNA maintain the correct structure
ex: Hfq |
|
|
Term
|
Definition
RNA molecule that resembles a repressor or activator
binds metabolites such as amino acids or vitamins and regulates gene expression by allowing or disallowing translation
at 5' end of mRNA |
