The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.

What is released in DNA replication?
(A) A deoxyribonucleoside triphosphate (dNTP). (B) During DNA replication, the 3′-OH group of the last nucleotide on the new strand attacks the 5′-phosphate group of the incoming dNTP. Two phosphates are cleaved off. (C) A phosphodiester bond forms between the two nucleotides, and phosphate ions are released.
What is the result of DNA replication quizlet?
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.
How the primers are removed after the completion of DNA replication?
All RNA primers will be removed by Rnase H and FEN1, leaving gaps in the newly-synthesized DNA strands (not shown.) DNA Polymerase and Ligase will replace all the RNA primers with DNA except the RNA primer at the 5′ ends of each newly-synthesized (blue) strand.
What phase does DNA replication occur?
In the eukaryotic cell cycle, chromosome duplication occurs during “S phase” (the phase of DNA synthesis) and chromosome segregation occurs during “M phase” (the mitosis phase).
What are the products of DNA replication composed of quizlet?
What are the products of semiconservative replication for a double-stranded DNA molecule? Two double-stranded DNA molecules, each consisting of one parental strand and one daughter strand.
What is the end product of DNA replication quizlet?
The final product of DNA replication is: two DNA molecules, each of which contains one new and one old DNA strand. The information carried by DNA is incorporated in a code specified by the: specific nucleotide sequence of the DNA molecule.
What is the product of replication quizlet?
What is the end product of replication? Two identical DNA strands. Each one is made of one original strand and one new strand. What is the role of DNA polymerase in replication?
What is the result of replication?
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell.
What happens at the end of DNA replication?
DNA replication ends when converging replication forks meet. During this process, which is known as replication termination, DNA synthesis is completed, the replication machinery is disassembled and daughter molecules are resolved.
What is the end result of transcription?
The outcome of Transcription is a complimentary strand of messengerRNA (mRNA).
What enzyme removes primers?
Removal of RNA primers and joining of Okazaki fragments. Because of its 5′ to 3′ exonuclease activity, DNA polymerase I removes RNA primers and fills the gaps between Okazaki fragments with DNA.
Why are RNA primers removed?
Because DNA ligase I is unable to join DNA to RNA, the RNA-DNA primers must be removed from each Okazaki fragment to complete lagging strand DNA synthesis and maintain genomic stability.
What process initiates primer?
Definition. Primer RNA is RNA that initiates DNA synthesis. Primers are required for DNA synthesis because no known DNA polymerase is able to initiate polynucleotide synthesis. DNA polymerases are specialized for elongating polynucleotide chains from their available 3′-hydroxyl termini.
