Examples range from simple molecules like CH3NH2 (methylamine) to large molecules like proteins and DNA. The two strands of the famous double helix in DNA are held together by hydrogen bonds between hydrogen atoms attached to nitrogen on one strand, and lone pairs on another nitrogen or an oxygen on the other one.
A-T pair has 2 hydrogen bonds while G-C pair has 3 hydrogen bonds. Hence, G C is more stronger than A="T". The content of adenine is equal to the content of thymine and the content of guanine is equal to the content of cytosine. This is Chargaff's rule, which is proved by the complementary base pairing in DNA structure.
The water molecules are bound to the platinum more loosely than the chlorines were. Cisplatin works by attaching itself to DNA in such a way that stops it functioning properly. The two strands of DNA are held together by hydrogen bonding between "base pairs". The diagram shows a tiny bit of a DNA double helix.
In DNA the hydrogen bonding between A and T helps to tie the two strands together into the double helix. That isn't relevant in RNA because it is only a single strand. However, you will find several examples in what follows on this and further pages where the ability of adenine (A) to attract and bond with uracil (U) is central
DNA - STRUCTURE. This page, looking at the structure of DNA, is the first in a sequence of pages leading on to how DNA replicates (makes copies of) itself, and then to how information stored in DNA is used to make protein molecules. This material is aimed at 16 - 18 year old chemistry students. If you are interested in this
This statement is about the effect of hydrogen bonding on the physical properties of a compound in which hydrogen bonds are present. Before you go on, you should find and read the statement in your copy of the syllabus. First, re-read the Chemguide page about hydrogen bonding, revising hydrogen bonding, but mainly
17 Jan 2017 A hydrogen bond is a weak type of force that forms a special type of dipole-dipole attraction which occurs when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. These bonds are generally stronger than ordinary
But for learning, concentrate on the hydrogen bonding between the base pairs which hold the two strands of DNA together. You should notice the way that adenine and thiamine are an exact fit as far as hydrogen bonding is concerned, as are guanine and cytosine.
In fact, this is happening lots of times along the very long DNA molecule. Lengths of chain become separated to form what are known as "bubbles". If you feel the need to see this in more detail, read the rest of this page, and then have a quick look at the links above. Some of the hydrogen bonds get broken and the two
