Give differences : $DNA$ and $RNA$
$DNA$ | $RNA$ |
$(1)$ It is double stranded with exception of some viruses. | $(1)$It is generally single stranded. |
$(2)$ It is the genetic material in all living organisms. | $(2)$ It is the genetic material in some viruses only. |
$(3)$ The sugar is deoxyribose. | $(3)$ The sugar is ribose. |
$(4)$ Nitrogenous base present are adenine, guanine, thymine and cytosine. | $(4)$ Nitrogenous bases present are adenine, guanine, cytosine and uracil.. |
$(5)$ It is less reactive, chemically and structurally more stable. | $(5)$ It is more reactive chemically and structurally less stable. |
$(6)$ It usually occurs inside the nucleus. and in some cell organelles. | $(6)$ Very little $RNA$ occurs inside the nucleus. Most of it is found in the cytoplasm. |
Give scientific reasons : Viruses can be used in the manufacturing proteins.
