DNA: The Molecule of Life

DNA, or deoxyribonucleic acid, serves as the genetic blueprint for all living organisms and plays a crucial role in inheritance, genetic diversity, and the functioning of cells.

DNA Structure

• Composed of two strands in a double helix structure
• Nucleotides consist of a sugar molecule, phosphate group, and nitrogenous base
• Adenine pairs with thymine, and cytosine pairs with guanine

DNA Replication

• Process of duplicating DNA prior to cell division
• Enzymes such as DNA polymerase and helicase are involved

Genetic Code and Protein Synthesis

• Sequence of nucleotides in DNA determines amino acid sequence in proteins
• Transcription and translation are key processes in protein synthesis

Mutations and Genetic Disorders

• Types of mutations: point mutations, insertions, deletions, and chromosomal mutations
• Impact of mutations on genetic traits and potential for genetic disorders

Applications of DNA Technology

• PCR, gel electrophoresis, and DNA sequencing techniques
• Utilization of DNA technology in fields such as forensics, medicine, agriculture, and biotechnology
