What is DNA and why is DNA important? DNA is able to determine an organism’s traits by determining the structure of an organism’s proteins DNA makes up segments of information called genes. Many genes make up one chromosome. There are multiple chromosomes found in the nucleus of every cell...
A protein structural domain that binds DNA and RNA, and that is found most commonly in transcription factors. It consists of a helix–turn–helix structure of 60 amino acids. GAR domain A Gly- and Arg-rich motif that adopts a repeated β-turn structure. It is found most commonly in prote...
DNA主要存在于细胞核中的染色体上,RNA主要存在于细胞质中,有少部分在核内。 Nucleotides 2.6.U1 The nucleic acids DNA and RNA are polymers of nucleotides. 2.6.S1 Drawing simple diagrams of the structure of single nucleotides of DNA and RNA, using circles, pentagons, and rectangles to represent phos...
DNA Shape is a double helix Each “step” of the helix is made by two connected nucleotides (monomer for nucelic acid) Each nucleotide has a sugar, phosphate and base There are 4 different bases that make pairs : A—T; and C—G DNA vs RNA Both are Nucleic Acids DNA has sugar Deoxyr...
(RNA), which carry the genetic instructions for the development, function, growth and reproduction of all known organisms and viruses. Structure of DNA and RNA: DNA macromolecules consist of two polynucleotide strands that are intertwined to form a double helix. RNA macromolecules typically exist as...

RNA-directed DNA methylation (RdDM) is the major small RNA-mediated epigenetic pathway in plants. RdDM requires a specialized transcriptional machinery that comprises two plant-specific RNA polymerases — Pol IV and Pol V — and a growing number of accessory proteins, the functions of which in th...
WRN’s C-terminal region, downstream of its helicase domain, contributes to these structure and sequence preferences. Our results strongly suggest that WRN specifically acts in telomeric HR processes possibly including T-loop formation. Results Preferential action of WRN on strand invasion intermediates ...
