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.
However, the DNA sense strand itself is not used to make protein by the cell. It is the DNA antisense strand which serves as the source for the protein code, because, with bases complementary to the DNA sense strand, it is used as a template for the mRNA. Since transcription results in an RNA product complementary to the DNA template strand, the mRNA is complementary to the DNA antisense strand.
