Answer:
DNA is the genetic material of all the living organism except some viruses. The structure and the characteristics of the DNA was well explained by Watson and Crick.
DNA is a double stranded molecule in which nitrogenous bases are linked together. Watson and crick explained that DNA strand are antiparallel. The antiparallel nature of the strand means one DNA gas a polarity of 5' to 3' direction whereas the another strand of the DNA gas polarity of 3' to 5' direction. These two strands has opposite polarity and runs in anti parallel directions. Thus, the DNA strand known as antiparallel strands.
Heterozygous- a certain gene that can carry two different alleles
Homozygous- a certain gene that carries two copies of the same alleles

Answer:
Option (B).
Explanation:
Mixture may be defined as the solution obtained by mixing of two or more substances together. Two different types of mixture are homogeneous mixture and heterogeneous mixture.
Homogeneous mixture may be defined as the mixture that has uniform composition throughout the mixture and cannot be separated easily by physical shaking process. Heterogeneous mixture are the mixtures that has different composition throughout the mixture and can be separated by simple shaking.
Thus, the correct answer is option (B).
