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.
GENOMES OF BACTERIA. So far in the course, we have been considering the genetics of eukaryotic organisms. Bacteria (prokaryotes) are much smaller in size than eukaryotic cells, and they have much smaller genomes. 1.hat common features are found in bacterial genomes that have been sequenced? The genome of E. coli (sequenced in 1997) is about 4 million base pairs with about 3000 genes. These numbers are quite average for bacteria; i.e., most have a genome size of several million base pairs containing a few thousand genes.
