The genetic material is stored in the form of DNA in most organisms. In humans, the nucleus of each cell contains 3 × 109 base pairs of DNA distributed over 23 pairs of chromosomes, and each cell has two copies of the genetic material. This is known collectively as the human genome. The human genome contains around 30 000 genes, each of which codes for one protein.

DNA replication is the semi-conservative synthesis of the cellular double-stranded DNA (parental molecule) to produce two double-stranded daughter molecules. Each one of the daughter molecules contains one parental strand, and one newly synthesized strand (Fig. 1, below). Therefore the process is said to be semi-conservative.

The process of DNA replication is highly conserved throughout evolution. Investigation into the replication machinery of simple organisms has helped tremendously our understanding of how the process works in human cells. The principles uncovered in simpler organisms extend uniformly to eukaryotic organisms. First, DNA replication occurs only in one direction (5’ to 3’). Second, DNA unwinding and DNA polymerization have to be coordinated to avoid formation of large single stranded (ss) DNA regions. Third, the presence of ssDNA is a checkpoint trigger. These rules are the fundamental basis for guaranteeing that the genetic information is properly duplicated and transmitted to the next generation.
FAQs
Write In Brief About Replication Of Dna? ›
DNA replication is the process by which the genome's DNA is copied in cells. Before a cell divides, it must first copy (or replicate) its entire genome so that each resulting daughter cell ends up with its own complete genome.
What is replication of DNA in brief? ›DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
What is the process of DNA replication in cell cycle? ›DNA replicates in the S phase of the cell cycle and initiates at specific regions in the DNA sequence known as DNA replication 'origins'. A number of proteins participate in DNA replication and the process is subject to scrutiny by cell surveillance mechanisms called cell cycle checkpoints.
What is the DNA replication quizlet? ›DNA replication is the process of producing two identical copies of DNA, in which each template for the synthesis of a new complementary daughter strand. The central enzyme involved is DNA polymerase, which catalyzes the joining of deoyribonucleoside 5'-triphosphates (dNTPs) to form the growing DNA chain.
Why is the replication of DNA important? ›DNA replication results in the duplication of DNA content in the cell, which is essential to maintain genetic continuity in the newly formed cell during cell division. Each cell receives the exact copy of DNA as a parent cell.
Which process best explains how DNA is replicated? ›DNA replication is done by a semi-conservative process in which the two strands separate and serve as templates for the complementary strands such that each daughter molecule has one parent strand and one new strand as shown in figure. If playback doesn't begin shortly, try restarting your device.
Where does DNA replication happen? ›DNA replication is the process of creating two identical daughter strands of DNA. DNA replication occurs in the nucleus in eukaryotic cells and in the nucleoid region in prokaryotic cells. DNA replication occurs in S phase during the cell cycle prior to cell division.
What is the conclusion of DNA replication? ›Conclusion. DNA replication is a highly regulated molecular process where a single molecule of DNA is duplicated to result in two identical DNA molecules.
What are the steps in DNA replication and protein synthesis? ›- Initiation. After RNA polymerase binds to the promoter, the DNA strands unwind, and the polymerase initiates RNA synthesis at the start point on the template strand.
- Elongation. The polymerase moves downstream, unwinding the DNA and elongating the RNA transcripts 5' --> 3'. ...
- Termination.
The synthesis of any macromolecule proceeds in three stages: initiation, elongation and termination. This is true for DNA replication as well. During initiation, DNA synthesis begins at a specific site, called an origin of replication.
Where does DNA replication start 3 or 5? ›
The need for accuracy probably explains why DNA replication occurs only in the 5′-to-3′ direction. If there were a DNA polymerase that added deoxyribonucleoside triphosphates in the 3′-to-5′ direction, the growing 5′-chain end, rather than the incoming mononucleotide, would carry the activating triphosphate.
