Chapter 5 This chapter briefly outlines the concept of DNA replication and intends to make the reader understand how DNA replicates itself. Lastly, translation of RNA into proteins will be elaborated. Most people think that these topics are in the realm of pure molecular biologist and the researcher.
DNA Replication (With Diagram) | Molecular Biology
DNA is the genetic material that defines every cell. Before a cell duplicates and is divided into new daughter cells through either mitosis or meiosis , biomolecules and organelles must be copied to be distributed among the cells. DNA, found within the nucleus , must be replicated in order to ensure that each new cell receives the correct number of chromosomes. Replication follows several steps that involve multiple proteins called replication enzymes and RNA. In eukaryotic cells, such as animal cells and plant cells , DNA replication occurs in the S phase of interphase during the cell cycle. The process of DNA replication is vital for cell growth, repair, and reproduction in organisms.
This is accomplished with the help of enzymes called helicases. Additional enzymes and proteins attach to the individual strands, holding them apart and preventing them from coiling upon them. The point at which the double helix separates is called the replication fork, because of the shape of the molecule.
Summarize the role of covalent bonds and hydrog Transcription and Translation The function of DNA in the living world is at once strangely complex and surprisingly simple. The genetic code carri
