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).

DNA is the chemical that chromosomes and genes are made of. DNA itself is made up of four simple chemical units that are abbreviated as A, G, C, and T. These letters are used to form three letter words that cells can read.A chromosome is simply a very long piece of DNA that cells can easily copy.NA is the chemical that chromosomes and genes are made of.
