DNA molecules have to be replicated prior tocell divisionto ensure that the two cells after cell division will have the same genetic content. In the early stages ofmitosis(prophase) andmeiosis(prophase I), DNA is replicated in preparation for the late stages where the cell divides to give ris...
Nuclear DNA is, of course, transmitted from parent(s) to offspring by nuclear division (meiosis or mitosis) via sexual or asexual (somatic) reproduction. Chloroplasts and mitochondria, however, replicate and divide independently of the nucleus and may be transmitted to offspring in a different ...

DNA makes a copy of itself in order to pass genetic information on to newly formeddaughter cells. In order for replication to take place, the DNA must unwind to allow cell replication machinery to copy each strand. Each replicated molecule is composed of a strand from the original DNA molecul...
Mitosis results in what cells and meiosis results in what cells? a. haploid, diploid b. diploid, haploid c. diploid, diploid d. haploid, haploid What is unique to Meiosis that does not take place in Mitosis? DNA is replicated once during which cell cycle(s)? a. Meiotic b. M...
Parental chromatids are replicated, forming two identical sister chromatids, connected by the centromere. Replication timing—the temporal order of chromatin replication and assembly—is slower in meiosis than mitosis, probably due to reduced origin firing (Pratto et al., 2021). High-density ...
In vivo, they are responsible for untangling replicated chromosomes and their absence at mitosis or meiosis ultimately causes cell death. Here we describe a micromanipulation experiment in which we follow in real time a single Drosophila melanogaster topoisomerase II acting on a linear DNA molecule ...
DNA is the genetic material that defines cells in bodies. In order for a cell to duplicate and divide into its daughter cells (either through the process ofmeiosisor mitosis), organelles and biomolecules must be copied first and then distributed among all cells. ...
When a human somatic cell undergoes mitosis, or cell division, the sister chromatids separate, resulting in two daughter cells with 46 chromosomes each. In organisms that reproduce sexually, the gametes (reproductive cells like eggs and sperm) are haploid cells. This means they have only one ...
