I can provide a brief text-based explanation of the DNA process without diagrams.
DNA, or deoxyribonucleic acid, carries genetic instructions for the development, functioning, growth, and reproduction of all known organisms. The process of DNA replication is fundamental for passing genetic information from one generation to the next.
1. **Initiation:** - DNA replication begins at specific sites called origins of replication. - Enzymes, such as helicase, unwind and separate the DNA strands, creating a replication bubble.
2. **Elongation:** - DNA polymerase adds complementary nucleotides to each of the original strands. - One strand, known as the leading strand, is synthesized continuously in the 5' to 3' direction. - The other strand, the lagging strand, is synthesized in short fragments called Okazaki fragments.
3. **Termination:** - The process continues until the entire DNA molecule is replicated. - RNA primers are removed, and the gaps are filled in with DNA nucleotides. - Ligase seals the nicks, resulting in two identical DNA molecules.
For a comprehensive understanding, it's recommended to refer to educational materials, textbooks, or online resources that include diagrams illustrating each step of the DNA replication process.
