Why is DNA Important in the Molecular Basis of Inheritance?
DNA is important in the molecular basis of inheritance because it is the molecule that carries the genetic information. Genes are located on chromosomes, and chromosomes are made of DNA. DNA is passed from parents to their offspring, and the genetic information it carries determines the characteristics of the offspring.
How is a Polynucleotide Formed by Joining Nucleotides?
A polynucleotide is formed by joining nucleotides. A nucleotide is composed of a nitrogenous base, a five-carbon sugar, and a phosphate group. The nitrogenous base is either adenine, cytosine, guanine, thymine, or uracil. The sugar is either ribose or deoxyribose. The phosphate group is attached to the sugar.
Genetic Code
The genetic code is the sequence of codons, which are the building blocks of DNA. These codons are translated into proteins, which are the basic components of all living cells. The genetic code is passed from parents to their children, and is the blueprint for the development and function of all living things.
