Hanks, who has won two Oscars but hasnât been nominated in 13 years, was overlooked for both âCaptain Phillipsâ and âSaving Mr. Banks.â. SNUB: âInside Llewyn Davis.â Even with nine best picture nominees, the Coen brothers, a perennial Academy favorite, lost out this time in the top category with their musical dramedy.
Anti-parallel strands. The DNA molecule is composed of two strands held together by hydrogen bonds. A single strand is different at its two ends. One end is called 5' (5 prime), the other is called 3' (3 prime). The names come from the notation for the two sugar carbon atoms which participate in the phosphodiester bonds. The different strands in the helix run in opposite (anti-parallel) directions. At each end of the double helix, one strand is 5' and the other is 3'. In the illustration, the 3' end is shown with a red arrowhead and the 5' end with the yellow connector.
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.
