DNA is better for the transmission of genetic information as compared to RNA. Both DNA and RNA can mutate. Which of the statements given above are correct?

Consider the following statements about the genetic materials DNA and RNA: DNA chemically is less reactive and structurally more stable as compared to RNA. DNA is better for the transmission of genetic information as compared to RNA. Both DNA and RNA can mutate. Which of the statements given above are correct? Correct Answer 1 and 3 only

The correct answer is 1 and 3 only.

Key Points

  • DNA chemically is less reactive and structurally more stable when compared to RNA.
    • Hence statement 1 is correct.
  • Both DNA and RNA can mutate.
    • In fact, RNA being unstable, mutate at a faster rate. 
    • Hence statement 3 is correct.
  • DNA is more stable is preferred for the storage of genetic information.
    • For the transmission of genetic information, RNA is better.
    • Hence statement 2 is NOT correct.

Additional Information

  • RNA can directly code for the synthesis of proteins, hence can easily express the characters.
    • DNA, however, is dependent on RNA for the synthesis of proteins.
    • The protein-synthesizing machinery has evolved around RNA.
  • Viruses having an RNA genome and having a shorter life span mutate and evolve faster.
  • RNA can directly code for the synthesis of proteins, hence can easily express the characters.
    • DNA, however, is dependent on RNA for the synthesis of proteins.
    • The protein-synthesizing machinery has evolved around RNA.

Read the passage carefully and choose the best answer to each question out of the four alternatives. Genetic variation is the cornerstone of evolution, without which there can be no natural selection, and so a low genetic diversity decreases the ability of a species to survive and reproduce, explains lead author Yoshan Moodley, Professor at the Department of Zoology, University of Venda in South Africa. Two centuries ago, the black rhinoceros – which roamed much of sub Saharan Africa – had 64 different genetic lineages; but today only 20 of these lineages remain, says the paper. The species is now restricted to five countries, South Africa, Namibia, Kenya, Zimbabwe and Tanzania. Genetically unique populations that once existed in Nigeria, Cameroon, Chad, Eritrea, Ethiopia, Somalia, Mozambique, Malawi and Angola have disappeared. The origins of the 'genetic erosion' coincided with colonial rule in Africa and the popularity of big game hunting. From the second half of the 20th century, however, poaching for horns has dramatically depleted their population and genetic diversity, especially in Kenya and Tanzania.
