Sentences with phrase «bound cell nuclei»

His approach to the top of the tree (home to eukaryotes, which wrap their DNA in membrane - bound cell nuclei) would rule biology classrooms for decades.

Not exact matches

A few years ago, Snyder's team and other researchers found that if NO reacts with GAPDH, GAPDH can then bind to another protein that whisks GAPDH away from its humdrum sugar metabolism tasks and into the nucleus, the cell's control center.

This is because yeast is eukaryotic: its cells have a membrane - bound nucleus that contains the genetic material, whereas bacteria are prokaryotic and do not.

Vitamin A and vitamin D are precursors to hormones that influence biological processes by entering the nucleus of a cell, binding to DNA, and altering the transcription of certain genes.

Disease processes often begin with mutations in the transcription factor, or in the DNA they bind to inside the nucleus of cells to regulate the complex interplay of genes needed for a healthy functioning body.

«We demonstrated that alpha - KGDH interacts with Gcn5 in the cell nucleus and found that tumor cell proliferation and tumor growth were inhibited when alpha - KGDH was blocked from entering the cell nucleus or by disruption of Gcn5's binding to succinyl - coenzyme A,» said Lu.

Choudhury and colleagues designed a series of experiments to find that DAZAP1 binds to a number of other proteins in the cell nucleus and promotes alternative splicing.

They work by binding to receptors inside a cell, which then travel to the nucleus and act on the DNA by turning select genes on and off.

Kiebler and his group had previously shown that the brain - specific RNA - binding protein Staufen2 (Stau2) plays a central role in the transport of mRNAs from the cell nucleus to synaptic ribosomes.

The genes for each transcription factor were made from different bits of DNA that code for the functional parts of proteins, such as a domain that can bind to DNA and another that provides the protein with access to the cell's nucleus.

Bacteria and Archaea, while genetically distinct, are both Prokaryotes, single - celled organisms lacking a membrane - bound nucleus.

SATB2 is a DNA - binding protein that facilitates structural organization of chromosomes in the nucleus of cells.

The Archaea domain consists of single - cell microorganisms that, like bacteria, have no cell nucleus or membrane - bound organelles, a sub-unit within a cell.

This visualization shows tightly - packed DNA in a mouse cell's nucleus at different stages of development, seen here in a semi-triangular form as a mature nerve cell; in a roundish shape as a multipotent stem cell; in a more oval form as a neuronal progenitor; and as a more fragmented structure that shows how removing a specialized binding protein (HP1β knockout) affects the structure of the DNA - packing material, called heterochromatin, in a mature neuron.

Here, we report that unphosphorylated STAT6 is present in the nucleus and may facilitate constitutive COX - 2 expression in NSCLC cells via binding to the COX - 2 promoter in association with p300.

Calcitriol mediates its biological effects by binding to the vitamin D receptor (VDR), which is principally located in the nuclei of target cells.

The hormone enters the cell, attached to a receptor, and then enters the nucleus of the cell where it binds directly to the DNA.
