What does DNA replication mean?

Answer 1

What is DNA replicated before?

Answer 2

DNA replication is a process during which DNA double helix opens like a zipper , new nucleotides are added along both strands of DNA by enzyme DNA polmerase and at last two molecules of DNA are formed. It takes place in S phase of interphase .

Answer 3

replication of DNA is the process of copying DNA strand to made another double stranded DNA. This process is important in genetics inheritance from one generation to another. the step of DNA replication include initiation, elongation, and termination.

Answer 4

DNA replication, the basis for biological inheritance, is a fundamental process occurring in all living organisms to copy their DNA. This process is "semiconservative" in that each strand of the original double-stranded DNA molecule serves as template for the reproduction of the complementary strand. Hence, following DNA replication, two identical DNA molecules have been produced from a single double-stranded DNA molecule. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication. In a cell, DNA replication begins at specific locations in the genome, called "origins" Unwinding of DNA at the origin, and synthesis of new strands, forms a replication fork. In addition to DNA polymerase, the enzyme that synthesizes the new DNA by adding nucleotides matched to the template strand, a number of other proteins are associated with the fork and assist in the initiation and continuation of DNA synthesis. DNA replication can also be performed in vitro (outside a cell). DNA polymerases, isolated from cells, and artificial DNA primers are used to initiate DNA synthesis at known sequences in a template molecule. The polymerase chain reaction (PCR), a common laboratory technique, employs such artificial synthesis in a cyclic manner to amplify a specific target DNA fragment from a pool of DNA.

Answer 5

The copying of the double-stranded DNA molecule, producing two identical DNA double helices.

Answer 6

Mainly DNA replication means to accurs in nucleus. Then, unwind and unzip it. And finally, occurs so that cells can divide.
