Which description of DNA replication is correct?
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 statement about DNA replication is true? The leading strand is syntesized continuously while the lagging strand is synthesized in a series of small fragments that are later connected. DNA polymerase synthesizes short fragments of DNA on the lagging strand during DNA replication.
DNA replication definition. the process in which one DNA molecule produces two identical DNA molecules, occurs before the cell divides.
DNA replication requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.
The statement pertaining to DNA replication that is false is D: Okazaki fragments are synthesized as part of the leading strand.
Which statement about DNA replication is FALSE? DNA ligase adds nucleotides to the lagging strand. This statement is FALSE. DNA ligase joins the Okazaki fragments in the lagging strand, turning it into a continuous strand.
The outcome of DNA replication is two DNA nearly identical DNA double helix molecules. Each DNA is made up of one DNA strand from the original DNA and a newly created strand.

DNA replication takes place in the (centrosome / nucleus) of a eukaryotic cell. DNA is replicated during the (M stage / S stage) of the cell cycle. DNA replication needs to occur so that every (cell / organism) will have a complete set of DNA following cell division.
- DNA primase lays down an RNA primer.
- DNA polymarase 3 puts together DNA nucletoids to make a long strand.
- DNA polymarase 1removes RNA and replaces with DNA.
- ligase links them together.
What is DNA replication called?
DNA replication (DNA amplification) can also be performed in vitro (artificially, outside a cell). DNA polymerases isolated from cells and artificial DNA primers can be used to start DNA synthesis at known sequences in a template DNA molecule.
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.
RNA polymerase transcribes molecules of RNA from DNA sequences during transcription, and is not involved in DNA replication.
The first step in DNA replication is to 'unzip' the double helix structure of the DNA? molecule. The separation of the two single strands of DNA creates a 'Y' shape called a replication 'fork'. The two separated strands will act as templates for making the new strands of DNA.
The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis. The elucidation of the structure of the double helix provided a hint as to how DNA is copied. Recall that adenine nucleotides pair with thymine nucleotides, and cytosine with guanine.
The correct option: The structure which is not true for a DNA molecule is B. Single-stranded.
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.
DNA replication occurs in the interphase nuclei of eukaryotic cells. DNA replication occurs before mitosis at the S-stage (synthesis) of the cell cycle.
The cellular process of creating two new DNA molecules from one original copy is called replication. Which statement is the BEST description of this process? DNA opens up and each strand is used as a template for a new strand.
Which of the following best describes this characteristic of replication? each new DNA molecule is made of pieces of the parent strand and alternating with segments that have been newly constructed from the free nucleotides.
Which statement best describes Strand characteristics as it relates to DNA replication quizlet?
What best describes strand characteristics as it relates to DNA replication? The leading strand is built continuously and the lagging strand is built in pieces.
DNA replication is the process by which DNA makes a copy of itself during cell division. This happens at the "S" phase of the cell cycle. DNA is a double helix, one strand going 5' to 3'(leading) and the other going 3' to 5'(lagging). Helicase opens up the two strands of the double helix.
The first step in DNA replication is the unzipping of DNA by the enzyme helicase. This opens up the DNA nucleotides so that they can be read and a complementary strand can be formed.

The last step of DNA Replication is the Termination. This process happens when the DNA Polymerase reaches to an end of the strands.
As a consequence, it is telomeres that are shortened with each round of DNA replication instead of genes. For example, in humans, a six base-pair sequence, TTAGGG, is repeated 100 to 1000 times. The discovery of the enzyme telomerase (Figure 9.2. 4) helped in the understanding of how chromosome ends are maintained.
Which of the following statements best describes the overall process of DNA replication? A double stranded DNA molecule is replicated to form two double-stranded DNA molecules, each containing one parent strand and one new strand.
Which of the following contributes to DNA replication accuracy? DNA replication accuracy is improved thanks to complementary base pairing rules. Bacterial cells use DNA replication to: copy their genetic material prior to binary fission.
Definition. 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.
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. This is required for growth and maintenance.
