Dna methylation is process that cells undergo frequentlly to 'turn off'' gene expression a methyl group, which is a small spherical shaped molecule comprised of one caron and 3 hydrogens, attaches at a specific site on a nitrogenous base. a nitrogenous base is either has a penthagonal shape or a hexagonal shape, which of the fllowing would most likely likit methylation from proceeding properly?
a. improper orientation of molecles
b. lack of energy
c. sub-optimal temperature
d. lack of a collision

the answer is probably A. improper orientation of molecules

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
