When and why does DNA need to be replicated?

Anonymous

∙ 14y ago

Updated: 6/17/2024

When cells divide, the new cells produced must have a full set of genes in order to function correctly. Genes are made of DNA so it is necessary to replicate (copy) the DNA before the cell divides.

DNA is replicated during the S phase of the cell cycle. If DNA is not replicated then the new cell will not have a copy of the DNA. If it does not have a copy of the DNA, then the cell will not be able to function properly.

DNA needs to be replicated before cell division so that each new cell receives an exact copy of the genetic information. This process ensures that genetic material is passed down accurately to daughter cells and maintains the stability of the organism's genome.

All cells need a copy of the DNA in order to work and function properly, and if DNA wasn't replicated, all of the cells would have to keep going back to the brain for instructions on what to do next, and the veins to the brain would clog, and the person would die.

DNA molecules be replicated so that new cells can synthesize the proteins necessary to maintain life functions, build, and repair cell parts and perform other metabolic functions.

What phase is DNA replicated in?

DNA is replicated in the S phase of Interphase

Is DNA replicated during mitosis or meiosis?

DNA is replicated during the S phase of the cell cycle before both mitosis and meiosis.

DNA is replicated at this time of the cell cycle?

DNA is replicated during the S phase of the cell cycle. This phase is when the cell synthesizes a copy of its DNA to prepare for cell division.

What are the phases when a cell's DNA is replicated?

The phases of DNA replication are initiation, where the DNA double helix is unwound and the replication bubble is formed, elongation, where new nucleotides are added to the growing DNA strands, and termination, where replication is completed and the newly synthesized DNA strands are proofread for accuracy.

What enzyme Cuts out the RNA primer on the replicated DNA molecule and replaces it with the appropriate DNA nucleotides?

The enzyme that cuts out the RNA primer on the replicated DNA molecule and replaces it with the appropriate DNA nucleotides is DNA polymerase I in prokaryotes and DNA polymerase delta in eukaryotes. This process, known as primer removal or primer excision, is essential for completing DNA replication accurately.
