7.1.1 Describe the structure of DNA, including the antiparallel strands, 3' -5' linkages and hydrogen bonding between purines and pyrimidines. DNA is made up of two strands. At one end of each strand there is a phosphate group attached to the carbon atom number 5 of the deoxyribose (thi...
Figure 3. DNA has (a) a double helix structure and (b) phosphodiester bonds. The (c) major and minor grooves are binding sites for DNA binding proteins during processes such as transcription (the copying of RNA from DNA) and replication....
Related to DNA structure:DNA replication DNA A. adenine T. thymine C. cytosine G. guanine DNA (dē′ĕn-ā′) n. A nucleic acid that carries the genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen...
The 64M-5 Fab recognizes the T(6–4)T segment dissociated from the complementary strand, indicating that the (6–4) photoproduct can be detected in double-stranded DNA as well as in single-stranded DNA using the 64M-5 antibody. The structure and recognition mode of the 64M-5 antibody ...
Crystal Structure of d(CCGGGACCGG)4 as a four-way junction at 1.6 angstrom resolution DNA-strand exchange is a vital step in the recombination process, of which a key intermediate is the four-way DNA Holliday junction formed transiently in m... A Chakraborty,P Mandal,N Gautham 被引量: ...
structure of nuleotides 3.3.2 State the names of the four bases in DNA. Adenine, Guanine, Cytosine and Thymine. 3.3.3 Outline how DNA nucleotides are linked together by covalent bonds into a single strand. Below is a diagram showing how nucleotides are linked to one another to form a str...

the double helix unwinds and each separated strand is used to synthesize a new strand. As the new strands form, bases are paired together until two double-helix DNA molecules are formed from a single double-helix DNA molecule. DNA replication is required for the processes ofmitosisandmeiosisto...
In general, it was demonstrated that the LNA/DNA:RNA duplex has a very high degree of order compared to dsDNA and dsRNA duplexes. The order parameters of the aromatic carbon atoms in the LNA/DNA strand are uniformly high, whereas a sharp drop in the degree of order was seen in the ...
Topology affects physical and biological properties of DNA and impacts fundamental cellular processes, such as gene expression, genome replication, chromosome structure and segregation. In all organisms DNA topology is carefully modulated and the superco
