Four different types of molecules, namely A, B, C and D were isolated from a primitive life form and studied to determine which of these would have the characteristics of an ancient genetic material. The molecules were incorporated into vectors, which are the phages whose genome were transformed into recombinant DNA. The phages were then made to infect the host bacteria. Transfection with A increased bacterial motility; B resulted in the formation of a pili allowing bacteria to here to surfaces; C causes the overproduction of a membrane protein while D resulted in increased metabolism of the bacterial food source, glucose. Which of the molecules is most likely a genetic material for this primitive life form? А. А В. В С. С

Question
Four different types of molecules, namely A, B, C and D were isolated from a primitive life form and studied to determine which of these would have the characteristics of an ancient genetic material. The molecules were incorporated into vectors, which are the phages whose genome were transformed into recombinant DNA. The phages were then made to infect the host bacteria. Transfection with A increased bacterial motility; B resulted in the formation of a pili allowing bacteria to adh to surfaces; causes the overproduction of a membrane protein while D resulted in increased metabolism of the bacterial food source, glucose.
