The DNA to be used as passenger or vehicle is isolated from the cell by lysing it with a suitable enzyme. The DNA is then isolated from other cell contents by ultracentrifugation and purified. Both the passenger and the vehicle DNA's are subsequentl..

>When bacteria were isolated from the dead mice, they were of living S-type and R-type. Griffith announced that it was because of a phenomenon other than mutation, which he called transformation. In 1944, O. T. Avery, McCleod and McCarty repeated the experiments of Griffith and found that..

Methods of Reproduction - There are basically two types of reproduction - asexual and sexual. This classification is based on the number of parents. Asexual reproduction involves only one parent and the offspring is genetically similar to the parent. Sexual reproduction involves two paren..

There are basically two types of reproduction - asexual and sexual. This classification is based on the number of parents. Asexual reproduction involves only one parent and the offspring is genetically similar to the parent. Sexual reproduction involves two parents and the offspring has a fusion of..

The semi conservative DNA replication was confirmed by an elegant experiment conducted by M. Meselson and F. W. Stahl in 1958. They grew the bacterium Escherichia coli in a medium containing nitrogen salts labeled with the stable heavy isotope 1 5 N. 1 5 N was incorporated into both ..

Methods to Determine Order of a Reaction - For determination of the order of a reaction, following methods are usually employed. a) Graphical Method b) Initial Rate Method c) Ostwald Method of Isolation..

Identify the equation wherein you would isolate a variable easily so that substitution method can be used to solve the linear system. 4 x + 7 y = 1 [Equation 1] x - 3 y = - 2 [Equation 2] => Equation 1 or Equation 2 or Both Equation 1 and Equation 2 or Neither Equation 1 nor Equ..

Choose the equation wherein you would isolate a variable easily so that substitution method can be used to solve the linear system. - x + y = 4 [Equation 1] 3 x - 6 y = -15 [Equation 2] => Neither Equation 1 nor Equation 2 or Equation 1 and Equation 2 or Equation 1 or Equation 2..
