I find myself instantly answering with the same response for some time now that is, âJames Hardie, HardiePlank Sidingâ is the best for Fire Resistance. Fiber cement siding, like Hardie, has great resistance to fire due to the cement like properties of the siding products.
What percentage of DNA do you inherit from your mother? I know it's hard to believe, but you actually inherit 50% of your DNA from each parent, unless something highly unusual happens, like spontaneous mutation.
Bert Ely, a biologist at the University of South Carolina, explains. Mitochondrial DNA (mtDNA) is passed from a mother to her children. Fathers cannot pass on their mtDNA, only the extra genetic information on their Y chromosome.Because mtDNA only comes from the mother, it does not change very much, if at all, from generation to generation. Mutations do occur, but not very often--less frequently than once per 100 people.ach mitochondrion contains its own DNA and its own protein-synthesizing machinery. They reproduce by splitting in two after they make a second copy of the DNA. In humans, the mtDNA is in the form of a circle that contains approximately 16,500 nucleotide base pairs of DNA.
