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.
Bacterial genomes can range in size anywhere from about 130 kbp to over 14 Mbp. Recent advances in sequencing technology led to the discovery of a high correlation between the number of genes and the genome size of bacteria, suggesting that bacteria have relatively small amounts of noncoding DNA.A striking discovery by Cole et al.ecent advances in sequencing technology led to the discovery of a high correlation between the number of genes and the genome size of bacteria, suggesting that bacteria have relatively small amounts of noncoding DNA.
