A bird will go broody whether or not you have a rooster. Some breeds will even go broody whether or not they have eggs; I have a Nankin hen who, in the absence of eggs, will gather small stones and set on them instead. I had someone call me once and ask me for a broody hen.
The DNA in a person is a combination of the DNA from each of their parents. Part of an organism's DNA is  non-coding DNA  sequences. They do not code for protein sequences. Some noncoding DNA is transcribed into non-coding RNA molecules, such as transfer RNA, ribosomal RNA, and regulatory RNAs).Other sequences are not transcribed at all, or give rise to RNA of unknown function. The amount of non-coding DNA varies greatly among species.ome noncoding DNA is transcribed into non-coding RNA molecules, such as transfer RNA, ribosomal RNA, and regulatory RNAs).

About DNA. 1  DNA is deoxyribonucleic acid, the molecules in cells that determine the genetic characteristics of all life. 2  It takes the form of a double helix (two strands coiled together). 3  DNA was first discovered in the 19th century by Miescher, from pus on bandages. This involves testing minisatellites one at a time, producing a simpler image than genetic fingerprinting. 2  It gives a pattern unique to a particular person, and is therefore suitable for forensic cases. 3  In the words of Professor Sir Alec Jeffreys, It does not solve crimes.
