Properties of Genetic Material is considered one of the most asked concept.
10 Questions around this concept.
In a DNA molecule
Read the following statements:
1. RNA can mutate at a faster rate than DNA
2. DNA chemically is less reactive and structurally more stable when compared to RNA
3. The 2'-OH group present at every nucleotide in RNA is a reactive group that makes RNA labile and easily degradable
4. RNA can mutate to form DNA
5. DNA being chemically less reactive is appropriate to act as the genetic material of viruses
Select the correct option:
Gerontology is old man logy, during ageing.
Which of the following best sums up the characteristics of genetic material?
Assertion: The genetic material possesses stability over generations.
Reason: Genetic material is protected by various mechanisms, such as DNA repair enzymes and histone proteins, which help maintain the stability of the genetic information.
Select the correct statements out of the following.
A molecule that can act as a genetic material must fulfil the traits given below, except
Given below are two statements:
Statement 1: In the RNA world, RNA is considered the first genetic material to evolve to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable.
Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, it resists changes by evolving a repairing mechanism. In light of the above statements, choose the most appropriate answer from the options given below:
