DNAis apolynucleotide, whosemonomer unitsare composed of a monophosphorylateddeoxyribosesugar linked to one of four nitrogenatednucleobases: twopurines, calledadenine(A) andguanine(G); and twopyrimidines, calledthymine(T) andcytosine(C)[124]. DNA is the basic information storage molecule in nature...
DNA In subject area: Physics and Astronomy DNA is a material that possesses unique properties as a molecular wire and as a nano-template, which makes it useful in the field of nano-electronics. It is important to comprehend the electric property and electronic states of DNA in order to effec...
DNA, the carrier and transmitter of genetic information in all living systems, consists of four different deoxynucleotide monomers.5Each monomer is formed with a phosphate group, a deoxyribose, and one of four nitrogen-involving nucleobases, while the nucleobases include thymine (T), adenine (A), ...
How specificity is conferred within gene regulatory networks is an important problem in biology. The basic helix–loop–helix PHYTOCHROME-INTERACTING FACTORs (PIFs) and single zinc-finger CYCLING DOF FACTORs (CDFs) mediate growth responses of Arabidopsis
The database is based on structured manual coding of elements by CSI (Crime Scene detectives). The computer algorithm then compares the pattern information associated with the query footwear impression to your whole database, going backEmricasan molecular weighta list of possible matches placed by pa...
retrotransposon RNP complexes from cells, new high-throughput (HT) DNA resequencing strategies, and cell culture retrotransposition assays, we have significantly increased our understanding of how the mammalian cell attempts to coexist with a molecular parasite whose unchecked activity could be bad news ...
Methanoarchaea are among the strictest known anaerobes, yet they can survive exposure to oxygen. The mechanisms by which they sense and respond to oxidizing conditions are unknown. MsvR is a transcription regulatory protein unique to the methanoarchaea.
Ribonucleic acid (RNA) is one of two key nucleic acids, the other being DNA. Messenger RNA (mRNA) is transcribed from DNA in the nucleus before heading into the cytoplasm and attaching itself to ribosomes to take part in translation, which is the synthes
稳定性是相对的,变异是绝对的 1.2 replicaiton unit and direction 1.2.1 Replicon A unit of the genome in which DNA contain a region from origin to terminus. Origin is the DNA sequence where a replicon initiates its replication. Origins tend to be A·T-rich to make opening easier Terminus is...
Similar toDnaA, DnaC is a member of the AAA+ ATPase family. Although many AAA+ proteins are ring-shaped oligomers, DnaC is purified as a monomer. Several studies showed that DnaC binds ATP, albeit with low affinity (KD~ 8μM), and is a weak ATPase. To support the idea that ATP ...
