Write the main structural difference between DNA and RNA. Of the two bases, thymine and uracil, which one is present in DNA?

Nitrogenous bases present in the list are adenine, thymine, uracil, and cytosine. Nucleosides present in the list are cytidine and guanosine.

When a nucleotide from the DNA containing thymine is hydrolyzed, thymine β-D- 2deoxyribose and phosphoric acid are obtained as products

RNA is single stranded.

The correct answer is (2) If deletion happen at 901st position than the remaining 98 bases specifying for 33 codons of amino acids will be altered.

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

(a) : RNA contains cytosine and uracil as pyrimidine bases while DNA has cytosine and thymine. Both have the same purine bases i.e. guanine and adenine.

(c) :- DNA contains cytosine and thymine as pyrimidine bases and guanine and adenine as purine bases.

c. the structural gene and the terminator regions

 P= weak base , Q=Strong acid, R=weak acid S= strong base , T= Strong acid , U=strong base

In DNA and RNA nitrogen is present in heterocyclic rings. Kjeldahl method can not be used to estimate nitrogen present in the ring because cannot be completely converted in to...
