Interphase is the period between cell divisions. During this time, chromosomes replicate—each DNA strand unzips into two strands while free-floating bases attach to the unzipped strands. The ...

For example, prior to undergoing meiosis, a cell goes through an interphase period in which it grows, replicates its chromosomes, and checks all of its systems to ensure that it is ready to divide.

Heterochromatin is more condensed than euchromatin. Typically, the more condensed chromatin is, the less accessible it is by transcription factors and polymerases. Long, slender DNA molecules wind ...

Several precautions should be followed in specifying and using interphase transformers. The transformer must support the ripple voltage between the two half-wave sections of an SCR interphase ...

Apomixis is a form of asexual reproduction that allows hybrid rice to propagate by seeds. Recently, a collaborative research ...

This is an important study examining the role of conserved PCH-2 protein at different stages of C. elegans meiosis. The authors use elegant molecular genetic approaches to provide convincing evidence ...

For 15 years, David Gilliver has been a pioneer in the technique of painting with light. A selection of the week's best photos from across the African continent and beyond. The former One ...

This valuable study uses robust time-dependent microscopy assays to show that during HIV-1 infection, the viral accessory protein Vif causes cell cycle arrest during metaphase and not G2/M as ...

Welcome to Mitosis vs. Meiosis. This half of the screen illustrates mitosis—the division of a cell's nucleus. Along with cytokinesis (the division of the rest of a cell), mitosis results in a ...
