There are five different nucleotides found in living organisms, adenine, thymine, uracil, guanine, and cytosine. These nucleotides are all created of the same basic components, a nitrogenous base, a pentose sugar, and a phosphate ion that makes them all acidic....
2.6.U3 DNA is double helix made of two antiparallel strands of nucleotides linked by hydrogen bonding between complimentary base pairs. 2.6.A1Crick and Watson’s elucidation of the structure of DNA using model making. DNA分子有两条方向平行(antiparallel)的多核苷酸链组成,中间的碱基依靠氢键联系在一起...

The spatial arrangement of these helices is maintained by two four–way junctions that exhibit extensive base–stacking interactions and sharp turns of the phosphodiester backbone stabilized by metal ions coordinated to nucleotides at these junctions. Although it is unlikely that the structure corresponds...

The nucleotide sequence and exon-intron organization of the proacrosin gene was determined. It consists of 6 exons and 5 introns of which one is located in the 5 untranslated region. The transcription initiation site was determined at position 471 (564 nucleotides upstream of ATC), TATA-and TA...
Eukaryotic genomes contain a large proportion of repetitive DNA sequences, mostly transposable elements (TEs) and tandem repeats. These repetitive sequences often colonize specific chromosomal (Y or W chromosomes, B chromosomes) or subchromosomal (telome
What are the structure and chemistry of nucleotides? Describe the structure of DNA, nucleotides and N-bases. Explain the mechanism by which DNA is replicated. What is the monomer of DNA? How do they form DNA? How does DNA form a double helix?
We know that nucleotides are the building blocks of DNA and RNA, but they also do a lot of other things. In order to understand why and how nucleotides perform their extremely important jobs, let's first go over what they're made out of and how they become nucleic acid. ...
