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).

What is DNA? â¢ Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms. â¢ This chemical substance is present in the nucleus of all cells in most living organisms. â¢ DNA controls: â All the chemical changes which take place in cells. â The kind of cell which is formed, (muscle, blood, nerve etc) is controlled by DNA. â The kind of organism which is produced (buttercup, giraffe, salmon, human etc) is controlled by DNA. DNA Subunits â¢ DNA is a very large molecule made up of a long chain of subunits. â¢ The subunits are called nucleotides . â¢ Each nucleotide is made up of: â a sugar called deoxyribose â a phosphate group -PO 4 and
