How Long Do Fleas Live. Flea Life Span. Fleas can live up to a year and a half when they have a food supply, the optimum temperature (70F to 85F), and ideal humidity (70%). In reality though, most live for an average of 2-3 months.
(1) The complete set of genes in an organism. (2) The total genetic content in one set of chromosomes. Supplement. The genome of eukaryotes is contained in a single, haploid set of chromosomes. The genome of bacteria is contained in a single chromosome whereas the genome of viruses is in the DNA or RNA. The human genome is made up of approximately 35000 genes, or three billion chemical base pairs. Word origin: a portmanteau of the words gene and chromosome.
A single copy of all the chromosomes is referred to as the genome. For example, humans have 23 pairs of chromosomes (for a total of 46 individual chromosomes) and the human genome consists of a single copy of each of those 23 chromosomes. Genome size is measured in terms of weight. The more DNA there is, the greater the weight, and the larger the genome.
