helical form meaning in Hindi

Examples

1. For example, many DNA binding proteins that have affinity for specific DNA binding sites bind DNA in only its double-helical form.
2. It is shorter and wider than B-DNA . RNA adopts this double helical form, and RNA-DNA duplexes are mostly A-form, but B-form RNA-DNA duplexes have been observed.
3. Many double-helical forms are possible; for DNA the three biologically relevant forms are A-DNA, B-DNA, and Z-DNA, while RNA double helices have structures similar to the A form of DNA.
4. Their helical form was derived from the smaller marble helical columns once thought to have been brought to Rome by the Emperor Constantine from Solomon's Temple in Jerusalem and which were used in the Old Saint Peter's Basilica ( See the article Solomonic column ).
5. In 1952, Rosalind Franklin and Raymond Gosling produced a strikingly clear x-ray diffraction pattern indicating a helical form, and in 1953, James D . Watson and Francis Crick demonstrated the molecular structure of DNA . Together, these discoveries established the central dogma of molecular biology, which states that proteins are translated from RNA which is transcribed by DNA . This dogma has since been shown to have exceptions, such as reverse transcription in retroviruses.
