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.
Eukaryotic DNA is packaged into chromosomes. Chromosomes are single strands of DNA. Bacterial DNA is packaged into a single chromosome that is a continuous loop. In both cases, the DNA must be folded or coiled so that it will fit into the cell.In bacteria the compaction involves DNA binding proteins that help to form initial loops followed by coiling of DNA.acterial DNA is packaged into a single chromosome that is a continuous loop.
