Microbial Genetics and Gene Transfer in
Microbiology with complete solutions latest 2026/27
UPDATE
What is the science of heredity?
Genetics
What is the central dogma of molecular biology?
Transcription and Translation
What are mutations?
Alterations of bacterial genes and/or gene expression that can cause disease, prevent treatment,
or be manipulated for human benefit.
How is gene expression controlled in prokaryotes?
By operons
What are chromosomes?
Structures containing DNA that carry hereditary information; humans have 23 pairs.
What are genes?
Segments of DNA that encode functional products, usually proteins.
What is a genome?
All the genetic information in a cell.
What is the difference between genotype and phenotype?
, Genotype is the genetic makeup, while phenotype is the expression of the genes.
What shape do bacterial chromosomes typically have?
A single circular chromosome.
What is the backbone of DNA made of?
Deoxyribose and phosphate.
What holds the two strands of DNA together?
Hydrogen bonds between A-T and C-G.
What is the direction of DNA replication?
5' to 3' direction.
What initiates DNA replication?
An RNA primer.
What are Okazaki fragments?
Short segments synthesized discontinuously on the lagging strand during DNA replication.
What is the role of DNA polymerase?
It adds nucleotides to the growing DNA strand and has proofreading capabilities.
What is transcription?
The process of synthesizing RNA from a DNA template.
What is the role of RNA polymerase?
