The DNA of bacteriophage lambda contains 48,502 nucleotide pairs forming a linear duplex. The 5′ ends of this DNA molecule have self-complementary single-stranded protrusions of 12 nucleotides that can anneal to form circles. Upon entry into the host cell, the DNA circularizes in the presence of DNA ligase.
One of the most commonly used practices to quantitate DNA or RNA is the use of spectrophotometric analysis using a spectrophotometer. A spectrophotometer is able to determine the average concentrations of the nucleic acids DNA or RNA present in a mixture, as well as their purity. Spectrophotometric … Prikaži več In molecular biology, quantitation of nucleic acids is commonly performed to determine the average concentrations of DNA or RNA present in a mixture, as well as their purity. Reactions that use nucleic acids often … Prikaži več An alternative method to assess DNA and RNA concentration is to tag the sample with a Fluorescent tag, which is a fluorescent dye … Prikaži več • IDT online tool for predicting nucleotide UV absorption spectrum • Ambion guide to RNA quantitation Prikaži več • Nucleic acid methods • Phenol–chloroform extraction • Column purification Prikaži več SpletThe absorbance at 260 nm (A(260)) is ubiquitously used for nucleic acid quantification. We show that following oxygenation, DNA solutions experience alterations in both spectral properties (hyperchromism in the UV region, lambda(max) 260 nm) and DNA conformation. The spectral changes caused by oxyge …

SpletThe lambda phage has an icosahedral head and a long tail terminating in a single fiber. At both ends of the 5′ termini are complementary 12-nucleotide single strand sequences that contribute to the cohesive ends (cos region) of the DNA.The tail of the phage latches on the host outer membrane receptor and injects phage DNA into the cell. population increase over timeSplet15. nov. 1996 · Abstract. Several procedures have been described for fluorescent labeling of DNA and RNA.
