Fifty years of making downwind sailing products means that we know what you need to sail off the wind, and we have a selection of poles and related fittings to do the job right for your boat. I can't imagine sailing downwind without my whisker pole. I make offshore passages for a living and I count on my Forespar* whisker pole.
Internal and external hydrogen bonds stabilize the DNA molecule. The two strands of DNA stay together by H bonds that occur between complementary nucleotide base pairs. Two hydrogen bonds occur between the adenosine and the thymine base pairs, and between the cytosine and the guanine there are three.
The bases in a DNA double helical chain are paired A-T and C-G. The A and T bases are bound by 3 hydrogen bonds per pair, and the C and G bases are bound by three hydrogen â¦ bonds per pair. How do the nucleotides in DNA bond with each other within a strand? I just did this paper in Biology, the answer is Hydrogen bonds!
