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).

Crick and Watson published their landmark paper on the structure of DNA in 1953 and it gave rise to an entirely new dimension in the field of science. DNA or deoxyribonucleic acid has got many facets and to understand them is very crucial for scientists and researchers. One of the facets is the antiparallel arrangement of DNA strands. Antiparallel means the two DNA strands are arranged in the opposite direction. A single DNA strand has two ends â one end has 5â-OH group-which is where a free phosphate group is attached to deoxyribose sugar.
