Results. 1  A total of 417 freediving accident cases were captured; 308 fatal and 109 non-fatal. 2  51Â±9 (40-63) fatal cases annually (Figure 1). 3  Incidents were reported from 56 countries. 4  46% in America; 11% in Australia; and single digits elsewhere. 5  Freediving victims were 41Â±17 (5-93) years of age (92% known) (Figure 2).
All of the DNA found in an organism is collectively referred to as the genome. The human genome is comprised of 23 pairs of linear chromosomes, and approximately 3000 megabases (Mb) of DNA, while thegenome of the bacterium Escherichia coli consists of a single 4.6 Mb circular chromosome.
Genetic information in bacteria is stored in the sequence of DNA in two forms, that is bacterial chromosome and plasmid. The following are the properties of a bacterial chromosome. 1  Location: Within nucleoid region, not surrounded by nuclear envelope.2  Number: 1 chromosome each cell.enetic information in bacteria is stored in the sequence of DNA in two forms, that is bacterial chromosome and plasmid.
