Describe the structure and function of DNA as the molecule of inheritance.
I need a better understanding of the below:
a. Describe the structure of DNA.
b. Discuss how the structure of DNA allows it to serve as the basis for inheritance.
c. Examine how meiosis allows DNA to be divided into gametes.
d. Describe how this relates to Gregor Mendel's patterns of inheritance.
DNA is a macromolecule and consists of repeating units called as nucleotides. Each nucleotide is composed of - phosphate group, pentose sugar and nitrogenous bases. DNA molecule is a double stranded helical structure in which sugar and phosphate forms a back bone and Nitrogenous bases are connected with the help of hydrogen bonds.
The Sugar and phosphate of the two nucleotides are connected by a Phosphodiester bond.
DNA molecules stores information regarding the makeup of the next generation in the form of sequences of nitrogenous bases. These information are passed in the gametes which serve as the basis of the inheritance.
