Question asked for the description on the structure of bacterial chromosome and plasmid with their properties.
Introduction:
Bacteria mostly contain single, circular chromosomes or linear chromosomes with double stranded DNA sequences. Bacterial genome is haploid in nature and ranges between
Explanation of Solution
Escherichia coli and Bacillus subtilis are widely used bacterial species with single chromosome, among which E. coli is mostly used, and it has
Bacterial chromosome has little amount of repetitive DNA sequences in multiple copies at intergenic regions, though they rarely transcribe, they serve a key role in replication, recombination, or in regulation of transcription. In bacterial chromosome, chromosomes are densely packed in a series of tight loops in association with a number of nucleoid associated proteins (NAP), i.e. they show several loops by supercoiling of DNA. There are two types of associated proteins a) small nucleoid-associated proteins and b) structural maintenance of chromosomes proteins (SMC).
All aspects are determined.
