17 Φεβ 2023 · DNA replication is the process through which a cell’s DNA forms two exact copies of itself. It occurs in all living organisms as it forms the basis of inheritance in all living organisms. The enzyme carrying out transcription is called DNA polymerase. The primary mechanism of DNA replication is similar across all organisms.
a simple (in principle) templating mechanism for replicating DNA into two identical copies. Only DNA (and in some instances RNA when, as in the case of the genomes of RNA viruses, it is used as a repository of genetic information) are self-complementary and hence capable of being replicated.
Replication—How DNA Is Produced. When extra copies of DNA molecules are needed—as might occur prior to cell division—the molecule undergoes replication. In this process the two DNA strands separate—that is, the “rungs” of the ladder are broken. Each freed strand then serves as a template from which a new strand is produced.
17 Μαρ 2022 · When a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis.
DNA has an antiparallel double helix structure, the nucleotide bases are hydrogen bonded together and each strand complements the other. DNA is replicated in a semi-conservative manner, each strand is used as the template for the newly made strand.
DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or...
One of the key players in DNA replication is the enzyme DNA polymerase, also known as DNA pol, which adds nucleotides one-by-one to the growing DNA chain that is complementary to the template strand. In prokaryotes, three main types of polymerases are known: DNA pol I, DNA pol II, and DNA pol III.
