True or False. If fale give the correct statement:
(i) A typical Mendelian dihybrid ratio of F2 generation is 3:1.
(ii) New nucleotides are added annd new complimentary strand of DNA is formed with the help of enzyme DNA polymerase.

New nucleotides are added and new complimentary strand of DNA is formed with the help of enzyme DNA polymerase.

A typical Mendelian dihybrid ratio of F_(2) generation is 3:1

State whether the following statements are true or false. If false write the correct statement. a. Thymine and cytosine are pyrimidines. b. The sequence of bases in a template strand does not determine the sequence of bases in the newly synthesised strand. c. The new strand formed in a continuous stretch of 5'-3' direction is called lagging strand. d. m-RNA is like a clover leaf. e. AUG is a terminating codon.

Each question has four choices, a,b,c and d,out of which only one is correct. Each question contains STATEMENT 1 and STATEMENT 2. if both the statements are true and statement 2 is the correct explanation of statement 1. If both the statements are true but statement 2 is not the correct explanation of statement 1. If statement is True and statement2 is false. If statement1 is false and statement2 is true. Statement 1: If x in [1,sqrt(3)], then the range of f(x)=tan^(-1)x is [pi/4,pi/3] Statement 2 : If x in [a , b], then the range of f(x)i s[f(a),f(b)]dot
