In this article we will discuss about the meaning and types of transduction of bacteria. Meaning of Transduction: The transfer of a small part of a bacterial genome from a donor to recipient bacterium through the agency of a bacteriophage is called transduction. It may be general or specialised. In generalized transduction almost any part of the donor's chromosome may [...]
In this article we will discuss about the process of transcription. The genetic information in the nucleotide sequence of DNA is passed on for protein synthesis through an intermediate messenger RNA (mRNA). A mRNA is a complimentary copy of one of the two DNA strands that make up a gene. The formation of an RNA copy from a DNA template [...]
In this article we will discuss about the presence of F factor in conjugation of bacteria. Bacterial cells may carry besides the main chromosome, one or more small DNA molecules in the cytoplasm called plasmids. Of the various kinds of plasmids, a few are involved in conjugation and are called conjugative plasmids. One such conjugative plasmid is the sex element [...]
