WebReplication is the process of doubling the DNA strands. The DNA strands are wound helically, therefore it is a separate task to process the strands for replication. The enzyme helicase is responsible for this separation. It breaks the hydrogen bonds between nitrogenous bases on the two antiparallel strands.

WebDISCUSSION 4 DNA replication is the process by which all the genetic materials of an organism is copied into two new daughter cells through the process of either meiosis or mitosis. This process is essential to conserve the information contained in the parental genes and allow an equal number of chromosomes to be distributed in the DNA … WebReplication of DNA is initiated with the introduction of the RNA primer via primase enzyme. Primer’s 3′ end is used as the initial point to add nucleotides by the DNA polymerase at the leading strand. The process terminates at the lagging strand through the synthesis of the Okazaki fragments. hardball baseball academy

WebRNA primers are key to initiating DNA synthesis. They provide the initiation sequence necessary for DNA polymerase to synthesize new strands. The RNA primer is introduced at the template DNA site by primase enzyme on both the leading and lagging strands. The 3'-OH free end of the primer is utilized by the polymerase enzyme to extend the growing ... WebThe foreign DNA that is placed into the cell is called alien DNA. Origin of replication The initiation of DNA synthesis occurs at a site called the origin of replication. Genetic engineering The modification of the genetic material (RNA or DNA) of organisms to use them to produce commercially important substances is called genetic engineering.

WebExplain the mechanism of DNA replication. Solution Replication depends on the pairing of bases between the two strands of DNA. The A base can only bind to a T, and a C can only bind to a G. In the DNA double helix, the bases of one strand face across and bind to those of the other strand. WebDNA replication fidelity is a key determinant of genome stability and is central to the evolution of species and to the origins of human diseases. Here we review our current …

WebDNA replication is the process of making new copies of double-stranded DNA by synthesizing new DNA strands. DNA replication is a bidirectional process as the strands of DNA are antiparallel, i.e., 3'-5' in one strand and 5'-3' in the other direction. The DNA polymerase synthesizes the DNA in 5'-3' direction. WebByju's Answer Standard X Biology Meiosis When cell has... Question When cell has stalled DNA replication fork, which checkpoint should be predominantly activated? A M B Both G2 /M and M C G1 /S D G2 /M Solution The correct option is C G2 /M In a typical eukaryotic cell, there are stages at which the cell "checks" to decide if it needs to proceed.

WebDNA Replication. Each strand of the DNA copies during replication of the DNA leading to the formation of a daughter DNA double helix. It contains one parental DNA strand and one newly synthesized DNA strand. There is a possibility at this juncture for any change in the sequence of the nitrogen base to take place, in short mutation to occur. WebSolution. The correct option is D. All the above. During DNA replication, both the strands of the parental DNA double helix serve as templates. A template strand is simply the strand from which a new complementary strand is synthesised. Complementary to the 3' → 5’ template, the leading strand is synthesised along the 5' → 3’ direction.
