The process by which a DNA molecule copies itself is called?

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.

What do you call the process of DNA replication from an existing DNA?

In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. ... 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.

How does a DNA molecule make a copy of itself?

Before a cell divides, its DNA is replicated (duplicated.) ... If the two strands of a DNA molecule are separated, each can be used as a pattern or template to produce a complementary strand. Each template and its new complement together then form a new DNA double helix, identical to the original.

What is the process of DNA replication quizlet?

dna replication - the dna molecule unwinds, and the two sides split. then new nucleotides are added to each side until twp identical sequences result. in prokaryotic cells, replication starts at a single site. ... dna replication, happens just before the cell divides.

What is the G2 phase do?

Gap 2 Phase

The last part of interphase is called the G2 phase. The cell has grown, DNA has been replicated, and now the cell is almost ready to divide. This last stage is all about prepping the cell for mitosis or meiosis. During G2, the cell has to grow some more and produce any molecules it still needs to divide.

What happens when a DNA molecule is replicated?

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

Why does the DNA need to make a copy of itself?

DNA Replication

DNA must replicate (copy) itself so that each resulting cell after mitosis and cell division has the same DNA as the parent cell. All these cells, the parent cell and the two new daughter cells, are genetically identical.

How does DNA molecule make a copy of itself quizlet?

What is method by which DNA replicate? the enzyme DNA helicase breaks the hydrogen bonds between bases on the two polynucleotide DNA strands. This makes the helix unwind to form two single strands. condensation reactions join the nucleotides of the new strand together - catalysed by the enzymes DNA polymerase.

What is transcription in DNA quizlet?

the synthesis of mRNA under the direction of DNA. RNA polymerase. an enzyme used to create pre-mRNA, binds to a specific sequence of the dNA called the promoter, separates DNA, transcribes but only uses one strand called the coding strand as a template, 5' - 3' RNA editing.

Where does the process of DNA replication begin quizlet?

Terms in this set (15)

DNA replication will begin at specific sites called origins of replication where the two DNA strands are separated opening up a replication bubble. At the end of each replication bubble is a replication fork. Which is a Y-shaped region and is the site of active replication.

What does G1 phase do?

G1 phase. G1 is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. During this time, the cell grows in preparation for DNA replication, and certain intracellular components, such as the centrosomes undergo replication.

What happens in the G1 and G2 phases?

During the G1 phase, the cell shows first growth by copying organelles and making the molecular building blocks which are necessary for later steps. During the G2 phase, the cell shows the second growth by making proteins and organelles and beginning to reorganize its contents in preparation for mitosis.

What does S phase do?

S phase. In S phase, the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase.

Where does DNA replication occur?

DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication.

What is the result of DNA replication quizlet?

The result of DNA Replication is half parent, half newly synthesized.
