Read the following five statements (A to E) and select the option with all correct statements : The cutting of DNA at specific locations became possible with molecular scissors'-restriction enzymes. Palindromes are groups of letters that form the same words read both forward and backward. Sexual reproduction preserves the genetic information, while asexual reproduction permits variation. DNA fragments are positively charged molecules , they can be separated by forcing them to move towards the cathode under an electric field. (E) Each restriction endonuclease recognises a specific palindromic nucleotide sequences in the DNA.
