WebThe sugar phosphate backbone is an important stuctural component of DNA. It consists of 5-carbon deoxyribose sugars and phosphate groups. These sugars are linked together by a phosphodiester bond, between carbon 4 of their chain, and a CH 2 group that is attached to a phosphate ion. WebRibulose -5-phosphate can be converted into two different 5-carbon molecules. One is the sugar used to make up DNA and RNA called, ribose -5-phosphate and this is the molecule we will focus on. Ribulose -5 …

WebMar 1, 2024 · Identify the sugar, phosphate, nitrogenous base, 5' and 3' carbons in a nucleotide and the key difference between DNA and RNA. Explain the structure of the double helix, including the role of hydrogen bonds and covalent (phosphodiester) bonds. Explain why the abundance of A is roughly equal to T and G is roughly equal to C in DNA. WebWatson and Crick proposed the double helix model for DNA. (a) The sugar-phosphate backbones are on the outside of the double helix and purines and pyrimidines form the “rungs” of the DNA helix ladder. (b) The two DNA strands are antiparallel to each other.

WebWatson wanted to try making a model in which just two phosphate-sugar-base chains were linked together. He thought it made sense for genes to come in pairs, partly because most organisms have two parents. Watson and Crick also decided to try orienting the bases towards the center of the pair. WebBSC 108 DNA Worksheet. sugar phosphate backbone forms with assistance from RNA polymerase to form an RNA strand. Hydrogen bonds of RNA and DNA helix break freeing the newly synthesized RNA strand.
