FAQs on Polynucleotide Formation Video Lecture - NEET

1. What are polynucleotides?
Ans. Polynucleotides are long chains of nucleotides that are joined together through phosphodiester linkages. They form the backbone of DNA and RNA molecules.
2. How are polynucleotides formed?
Ans. Polynucleotides are formed through a process called polymerization. During polymerization, nucleotides are joined together through the formation of phosphodiester bonds between the phosphate group of one nucleotide and the sugar group of another nucleotide.
3. What is the significance of polynucleotide formation?
Ans. Polynucleotide formation is of great significance as it allows for the storage and transmission of genetic information. DNA, a double-stranded polynucleotide, carries the genetic instructions for the development and functioning of living organisms. RNA, a single-stranded polynucleotide, plays a crucial role in protein synthesis.
4. What are the differences between DNA and RNA polynucleotides?
Ans. DNA is a double-stranded polynucleotide, whereas RNA is a single-stranded polynucleotide. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA uses the nitrogenous bases adenine (A), cytosine (C), guanine (G), and thymine (T), while RNA uses uracil (U) instead of thymine.
5. How does polynucleotide formation affect genetic diversity?
Ans. Polynucleotide formation plays a crucial role in genetic diversity. Through the process of DNA replication and meiosis, genetic information can be accurately transmitted from one generation to the next. Additionally, genetic diversity can arise through mutations in the nucleotide sequence of polynucleotides, leading to variations in traits among individuals.
