DNA replication Definition of DNA replication. DNA replication: A complex process whereby the 'parent' strands of DNA in the double helix are separated, and each one is copied to produce a new (daughter) strand. This process is said to be 'semiconservative' because one strand from each parent is conserved and remains intact after replication has taken place.

In one paragraph, explain the process of DNA replication!!!? DNA replication or DNA synthesis is the process of copying a double-stranded DNA molecule. Both strands in DNA run anti-parallel to each other and are complementary to one another.NA replication begins with the unzipping of the parent molecule as the hydrogen bonds between the base pairs are broken. Once exposed, the sequence of bases on each of the separated strands serves as a template to guide the insertion of a complementary set of bases on the strand being synthesized.

DNA replication In a cell, DNA replication begins at specific locations, or origins of replication, in the genome. Unwinding of DNA at the origin and synthesis of new strands results in replication forks growing bi-directionally from the origin.

DNA replication DNA replication is the process of producing two identical replicas from one original DNA molecule. This biological process occurs in all living organisms and is the basis for biological inheritance.NA is made up of two strands and each strand of the original DNA molecule serves as a template for the production of the complementary strand, a process referred to as semiconservative replication. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.

Cells Can Replicate Their DNA Precisely Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. 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 DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.NA 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 DNA, as the parent cell.

DNA replication In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. This process occurs in all living organisms and is the basis for biological inheritance. DNA is made up of a double helix of two complementary strands. During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication.

- DNA replication is the process of producing two identical replicas from one original DNA molecule. This biological process occurs in all living organisms and is the basis for biological inheritance.NA replication can also be performed in vitro (artificially, outside a cell). DNA polymerases isolated from cells and artificial DNA primers can be used to initiate DNA synthesis at known sequences in a template DNA molecule.

DNA Replication and Checkpoint Control in S Phase DNA replication is the process by which DNA makes a copy of itself during cell division. 1  The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA molecule. The primer acts as the starting point for DNA synthesis. 2  DNA polymerase binds to the leading strand and then ‘walks’ along it, adding new complementary nucleotide bases (A, C, G and T) to the strand of DNA in the 5’ to 3’ direction. 3  This sort of replication is called continuous.

Prokaryotic DNA replication Prokaryotic DNA replication. Prokaryotic DNA replication is the process by which a prokaryote duplicates its entire genome into another copy that is passed on to daughter cells. Although it is often studied in the model organism E. coli, other bacteria show many similarities.

PROKARYOTIC CELL ANATOMY: From DNA Replication at ThinkQuest. In general, DNA is replicated by uncoiling of the helix, strand separation by breaking of the hydrogen bonds between the complementary strands, and synthesis of two new strands by complementary base pairing.Replication begins at a specific site in the DNA called the origin of replication.ranscription is the process through which a DNA sequence is enzymaticaly copied by an RNA polymerase to produce a complementary RNA. Or, in other words, the transfer of genetic information from DNA into RNA.
