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 [...]
In this article we will discuss about the meaning of site-specific recombinases of bacteria. During evolution of multiple antibiotic resistance, bacteria seem to have made use of enzymes known as site-specific recombinases. Each type of site-specific recombinase binds with a specific nucleotide sequence in double stranded DNA. When the site is present in each of the two duplex molecules, the [...]
