why dna replication is semiconservative?
5089
DNA replication is a semi-conservative process, because when a new double-stranded DNA molecule is formed: One strand will be from the original template molecule. One strand will be newly synthesised.

One of the key molecules in DNA replication is the enzyme DNA polymerase. DNA polymerases are responsible for synthesizing DNA: they add nucleotides one by one to the growing DNA chain, incorporating only those that are complementary to the template.

The purpose of DNA replication is to produce two identical copies of a DNA molecule. This is essential for cell division during growth or repair of damaged tissues. DNA replication ensures that each new cell receives its own copy of the DNA.

During DNA replication, the hydrogen bonds must be broken between the complementary nitrogenous bases in the DNA double helix. Once this is accomplished, either side of the DNA molecule can act as a template to produce another double stranded DNA molecule.

DNA ligase works to join the Okazaki fragment during the lagging strand synthesis in semiconservative DNA replication. ... DNA polymerase catalyzes phosphodiester bond formation between the terminal 3′–OH of the primer and the α-phosphate of the incoming triphosphate.

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.

Terms in this set (47) The sole purpose of DNA replication is to generate identical DNA molecules, as they are the blueprint that makes life possible. There are reasons that there DNA replication goes through a slightly different process to repair damage.

It is now well known that DNA polymerases synthesize new DNA strands according to the template DNA, using deoxynucleotide triphosphates during DNA replication. DNA ligase works to join the Okazaki fragment during the lagging strand synthesis in semiconservative DNA replication.

RNA primers are needed to begin replication because DNA polymerase is unable to do it alone. DNA transcription does not have the same problem because RNA polymerase is capable of initiating RNA synthesis.

The cell has multiple mechanisms to ensure the accuracy of DNA replication. ... DNA is double-stranded. The strands split apart and serve as templates for new copies. Every time a stem cell replicates its DNA and splits into two cells, the cell that remains a stem cell will keep the same strand of DNA.

Differences. DNA replication occurs in preparation for cell division, while transcription happens in preparation for protein translation. DNA replication is important for properly regulating the growth and division of cells. ... Transcription only occurs when a gene is turned on.
1392065
DNA replication is the action of DNA polymerases synthesizing a DNA strand complementary to the original template strand. ... In eukaryotes, the vast majority of DNA synthesis occurs during S phase of the cell cycle, and the entire genome must be unwound and duplicated to form two daughter copies.

DNA replication is the process of making new copies of DNA. Transcription is the process by which DNA is copied (transcribed) to RNA. ... DNA replication is important for properly regulating the growth and division of cells.

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.
1204487
Because each DNA strand can be used to make the other Strand, the strands are said to be complementary. Process of copying DNA prior to cell division. Ensures that each resulting cell has the same complete set of DNA molecules. ... Then, 2 new complementary strands are produced following the rules of Base Pairing.

RNA stays in the aqueous phase since the pkA of its groups is greater than that of DNA (it is more acidic). This feature enables separating one molecule without destroying the other.

Replication refers to the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules while duplication refers to the process by which the amount of DNA inside the nucleus gets doubled. Hence, this is the main difference between replication and duplication of DNA.
