The lambda-max for dna and rna falls at
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. SpletThe contamination of the sample by substances that absorb at 260 nm leads to an overestimation of the amount of DNA and thus possibly to a lower DNA concentration than required for a subsequent downstream procedure. Many of these impurities can be estimated by measuring the absorption of the sample at wavelengths other than 260 nm.
