State any one reason to explain why RNA viruses mutate and evolve faster than other viruses

Text Solution

Verified by Experts

RNA viruses mutate and evolve faster than other viruses because RNA is more reactive and unstable. Its unstable nature is because of presence of 2'-OH group of ribose sugar, uracil and enzymatic properties of RNA

Study the following carefully and explain why mutation (A) did not cause any sickle cell anemia in spite of change in the molecular structure of the gene which codes for Haemoglobin, when as a similar mutation (B) did. (The question is based on properties of the genetic code. c= codon, a = amino acid, Hb = Haemoglobin) Codons for Hb: C_1 - C_2 -C_3 -C_4 - C_5 -G AA -GAA- C_8 ... Amino acids in Hb : a_1-a_2-a_3-a_4-a_5 - Glutamic acid- Glutamic acid - a_8 ...... (Normal Haemoglobin ) Mutation (A) : C_1 -C_2 - C_3 -C_4 -C_5-GAG-"GAA"-C_8...... a_1-a_2 - a_3-a_4-a_5 -Glutamic acid -Glutamic acid - a_8 ....

The numbers 2,3,4,5 and 6 written on five pieces of paper. Theses pieces of paper are put in a bag and then mixed thoroughly. A man draws at random two pieces of paper from the bag one after the other without replacement. Describe the following events associated with this random experiment : A : the number on the first piece is less than the one on the second piece, B: the sum of the numbers on the two pieces is 8 or 9 , C: the number on the first piece is odd and D: the number on the second piece is greater than 4. Is there any pair of events which are mutually exclusive?

Two wires of equal length, one of aluminium and the other of copper, have the same resistance. Which of the two wires is lighter ? Hence, explain why aluminium wires are preferred for overhead power cables. (rho _(Al)=2.63xx10^(-8)Omega -m ,P_(Cu)=1.72xx10^(-8)Omega -m , relative density of Al=2.7,of cu =8.9)

Give reason for the following in one or two sentences. "Acid catalysed dehydration of t-butanol is faster than that of n-butanol".

In the 1950s, there were hardly any mosquitoes Delhi. The use of the pesticide DDT on standing water killed their larvae. It is believed that now there are mosquitoes because they evolved DDT resistance through the interaction of mutation and Natural Selection. Pointwise, state in a sequence how that could have happened.
