It means when the DNA is unzipped into two strands each strand serves as a template for the synthesis of another new strand. So, when the strands come back together in the double helix one strand is an old strand and one is a new strand with you now have double the DNA you started with; four strands in all.
A child is unable to have DNA from two men. This is because there must be two gametes that are able to sexually reproduce.
Then that DNA came from the father of the baby.
Yes, men who have had vasectomies still have DNA in their semen. The vasectomy procedure blocks the vas deferens, the tubes that carry sperm, preventing sperm from reaching semen. Semen is still produced by the body, but it does not contain sperm.
When two men who are closely related are suspected of contributing the DNA resulting in a pregnancy, the initial DNA "simple" testing would likely not be able to pin-point which man is the father. But further DNA testing can eliminate one or the other.
The first picture and model of the DNA structures were made from Rosalind Elsie Franklin. Over the years William Watson and Francis Crick stole the idea from her and worked out the structure of DNA as if they invented it.
That is completely dependent on the man in question however most men regard them no differently to anyone else no matter what nationality.
its in our DNA
James Watson and Francis Crick discovered the structure of DNA.
