Question

Nucleoprotein gave most probably the first sign of
A) Life
B) Amino Acid
C) Soil
D) Sugar

Answer 1

Nucleoproteins are that class of proteins that are structurally linked with either RNA or DNA which are the nucleic acids. Various kinds of nucleoproteins include nucleosomes, viral nucleocapsid proteins and nucleosomes.

Complete answer:
Let us go through each of the options carefully,
Option A: DNA holds the information or code for all the cell’s activities and this particular information is translated by the RNA into proteins which can then carry out specific functions. Nucleoproteins were self replicating molecules which comprised proteins and nucleic acids connected together which were described as free living genes and depicted the first sign of life. Therefore, this option is correct.

Option B: Amino acids are organic compounds which conjugate together to form various protein complexes. This is not exactly a sign which would be depicted by a nucleoprotein and does not really fit in the question asked. Therefore, this option is incorrect.

Option C: This option is very vague and not really related to the question so we can ignore it. Therefore, this option is incorrect.

Option D: Sugar in this case, is a vital component for DNA and RNA which plays a key role in their distinction. This option also does not particularly fit well for the given question and is not specific. Therefore,this option is incorrect.

Hence the correct answer is option ‘A’.

Note: A deoxyribonucleoprotein (DNP) is a linkage of DNA and protein- a nucleosome where the DNA is wrapped around histone proteins to eventually form the chromatin.A ribonucleoprotein (RNP) comprises RNA and protein- ribosomes which are very important in the process of translation and eventually synthesizes other proteins.
