The lions roared in their cages.

The animals are kept in very small cages.

Interestingly, in cultured mouse or human cells, the mammalian SIR2 gene determines a cell's response to DNA damage.

Htt function Htt is expressed in all mammalian cells.

The chromosomes in our cells contain the whole of our genetic material.

You who sit in the darkened prisons, enduring interrogations and suppression.

Free radicals are produced continuously in all cells as part of their normal functioning.

It also blocks the adhesion molecules on the endothelial cells that line blood vessels, which attract T cells.

Place tents in some of the remaining squares, under some conditions

Some viruses, called satellites, can replicate only within cells that have already been infected by another virus.

Intriguingly, cancer cells respond abnormally to death signals. Some of the genes involved in the suicide program are the same genes that are altered in cancer cells.

Not meaning it kind of sits around inside cells going, I want to get copied.

The field is in the process of gaining a better understanding of a host of complex systems within individual cells.

Some of the genes involved in the suicide program are the same genes that are altered in cancer cells.

These techniques have allowed the discovery and detailed analysis of the many molecules and metabolic pathways in cells.

At first when I heard of cancer stem cells, I didn't really know how to put the two together. I'd heard of stem cells, and I'd heard of them as the panacea of the future the therapy of many diseases to come in the future, perhaps.

In response, many plant viruses have evolved elaborate mechanisms to suppress the RNAi response.

The Cynical Arab, a Lebanese American blogger, takes issue with the rhetoric used by Eltahawy in a piece called On Caged Birds and Liberators .

Nomenclature Alternative names for this enzyme are human hexokinase IV, hexokinase D, and ATP D hexose 6 phosphotransferase, EC 2.7.1.1 (previously 2.7.1.2).

However, it was well known that proteins are structural and functional macromolecules, some of which carry out enzymatic reactions of cells.

Dendritic cells and macrophages are not so fast, and phagocytosis can take many hours in these cells.

This clock is found in a wide range of fly cells, but the clock bearing cells that control activity are several dozen neurons in the fly's central brain.

Currently, there are three main hypotheses that aim to explain the origins of viruses Regressive hypothesis Viruses may have once been small cells that parasitised larger cells.

But in today s factory farms, pregnant sows are kept in crates so narrow that they cannot turn around, or even walk more than a step forward or backward.

Animals have Piwi interacting RNAs (piRNA 29 30 nt) that are active in germline cells and are thought to be a defense against transposons and play a role in gametogenesis.

Measures to improve the welfare of laying hens, which are typically kept crammed into bare wire cages with no room to stretch their wings, are also being phased in.

Will we permit doctrinaire religious views to block our ability to explore the enormous potential of embryonic stem cells and thereby lift the yoke of disease from tens of millions of people?

In most countries, it is possible to visit zoos and see bored animals pacing back and forth in cages, with nothing to do but wait for the next meal.

An idea of the complexity of the metabolic networks in cells that contain thousands of different enzymes is given by the figure showing the interactions between just 43 proteins and 40 metabolites to the right the sequences of genomes provide lists containing anything up to 45,000 genes.

The movement toward more ethical consumption has made significant gains in the United States as well, as consumers increasingly turn to organic, locally produced foods, and eggs from hens not kept in cages. In the UK, a survey has found that half of those shown the Fairtrade symbol recognized it and understood that it refers to products that give a better deal for Third World farmers.

The movement toward more ethical consumption has made significant gains in the United States as well, as consumers increasingly turn to organic, locally produced foods, and eggs from hens not kept in cages.

Khazali says prisoners who escaped mass executions in 1988 and remain alongside him in prison, and have told him about coffins (some prisoners were put in coffins as a torture) and iron cages.
