Watson and crick model of DNA | Class 12 Biology
About This Video ........................
In This Video Lecture You Will Learn Basic Concept Of Watson and crick model
Double Helical Structure of DNA (Watson and Crick’s Model)
Learning informally of Franklin’s results, before they were published in 1953, James
was substantially correct. They’ proposed that molecule is a simple double helix, with
thymine. Consequently adenine and thymine will always occur in the same proportion
Watson and Francis Crick, two young researchers in University’ of Cambridge, quickly
worked out a likely structure of the DNA molecule which we now know
running 3’ to 5’ and the other 5’ to 3’. The base pairs are planar (lat) and stack 0.34nm
their model, base pairs always consist of purines, which are large, pointing toward
stabilized as a duplex DNA molecule composed of two antiparallel strands, one chain
thymine, while guanine forms three hydrogen bonds with cytosine. Adenine will not form
Because hydrogen bonds exist between the bases in a base pair, the double helix is
apart as a result of hyperphobic interactions contributing to the overall stability of
the basis of two strands pointed inward toward each other. forming base-pairs. In
pyrimidines which are small, keeping the diameter of the molecule a constant 2 nm.
the molecule (Fig. 20.3). In the double helix, adenine forms two hydrogen bonds with
in any DNA molecule, as well guanine and cytosine, because of this base pairing.
About This Channel.....................
I make these videos cause I love to draw and connect the complexity of science and medicine into art. I'm not saying. I'm 100% correct in all my videos, but I do try to obtain the information from credible sources.
One-stop destination for all biology lectures.
_ students in class 11, 12 or appearing for competitive medical exams ( NMDCAT ) will find it very beneficial
_ The videos are categories under various heading to make the students life simplified
