In a nucleus, the number of RNA nucleoside triphosphates is 10 times more than the number of DNA nucleoside triphosphates

Solution: Let the length of the shorter side be x metres. Thus the length of the longer side=(x+30) m Length of the diagonal=(x+60)m Each angle of a rectangle=90 degrees By Pythagoras Theorem, (diagonal)2=(shorter side)2+(longer side)2 (x+60)2 ...

(c) mitochondria 

There are two different types of nucleic acid polymerases.  DNA-dependent DNA polymerases  DNA-dependent RNA polymerases The DNA-dependent DNA polymerases use a DNA template for synthesizing a new strand of DNA, whereas DNA-dependent RNA...

RNA is more labile and prone to degradation (owing to the presence of 2’ OH group in its ribose). Hence heat-killed S-strain may not have retained its ability to transform...

(b):   DNA RNA (a) Pyrimidine Cytosine Cytosine derivatives Thymine Uracil (b) Purine Adenine Adenine derivatives Guanine Guanine (c) Sugar Deoxyribose Ribose

(c) the number of nucleons in the nucleus

(d) sometimes more than and sometimes equal to its atomic number.

c. Such a DNA is called 0:1:3.

                                         Structural difference DNA RNA 1. The sugar present in DNA is 2-deoxyD-(–)-ribose 1. The...
