Physiology & Growth Of Bacteria//Microbial genetics Flashcards
What is cell growth ?
The orderly increase in the sun of all the components of an organism
Cell shape & size are maintained by the _ layer
Peptidoglycan
What is bacterial population growth
Occurs are the mass cellular components increases
*is exponential in nature
What are the phases of bacterial Growth ?
A - lag phase
B - exponential phase
C - stationary phase
D - decline phase
What are the macro elements involved in bacterial nutrition
Carbon, nitrogen, phosphorus, oxygen, sulfur, hydrogen
What are the macro elements involved i bacterial nutrition
Carbon, nitrogen, phosphorus, oxygen, sulfur, hydrogen
Anaerobically Two pathways used by pyruvate in bacterial nutrition include;
1) Embden Meyerhoff pathway
2) Enther- Dondoroff pathway (net yield of 1ATP for every glucose molecule processed)
What is heredity ?
Constancy & change in physiologic functions that forms the properties of organisms
What is genome
Total complement of genes in a cell/chromosome
What is gene (cystron)
Segment of DNA that Carries in its nucleotide sequence information for a specific biochemical or physiologic property
Operan
Structural & regulatory gene
Plasmid
Small circular double stranded extra chromosomal DNA which is invariable calabar of self propagation and sustenance
Transposon
Conjugative & transmissible plasmid
Episome
Plasmids capable of reverse integration into the chromosome
Genotype
Hereditary potential of an organism
Changes with change in DNA sequence
