ribosome

A small particle in the cytoplasm of a cell, typically consisting of fragmented endoplasmic reticulum to which ribosomes are attached.

Several ribosomes may become attached to a single mRNA strand; such a combination is called a polysome.

Thus, each of our cells appears to carry in its ribosomes "fossil" evidence of a primordial RNA world.

Ribosomes account for a large proportion of the total RNA of a cell.

ER lacking ribosomes is called smooth ER is involved with lipid synthesis, including phospholipids and steroids.

Some antibiotics work by gumming up the ribosomes of bacteria, allowing those bacteria to be stopped at no danger to their host.

Some of the cell's ribosomes are attached to the ER and the proteins they manufacture are inserted directly into the space inside the ER.

Proteins newly formed on ribosomes detach and migrate to other parts of the cell to be used.

The ribosomes , made up of RNA and protein , are found either lining the endoplasmic reticulum or free within the cell .

Understanding ribosomes is important for a scientific understanding of life.

The ribosomes were flash-frozen at various mid-swivel and mid-ratchet configurations and examined under a powerful electron microscope.

The blueprints are transformed into living matter through the work of structures called ribosomes.

Bacterial cells contain genetic material in a single chromosome, and ribosomes for synthesizing proteins.

Ribosomes -- particles composed of RNA and proteins that are the sites of protein synthesis.

The blueprints become transformed into living matter through the work of ribosomes.

Flux of genetic information through messenger RNAs, transfer RNAs and ribosomes from genes to proteins forms the basis of molecular biology.

"Forget about all the technical issues of making mirror ribosomes, mirror peptides, and mirror DNA, " he says.

There was a mild breakdown of myelin and many free ribosomes.

Under normal growth conditions, the majority of the ribosomes is engaged in protein synthesis.

If the sequence of letters in the DNA forms the blueprint for life, ribosomes are the factory floor.

The lymphocyte with rich mitochondria, free ribosomes and RER in the cytoplast had double membrane and obvious nuclear pores.

Viral protein is synthesized in the cytoplasm on polyribosomes composed of virus-specific mRNA and host cell ribosomes.

Many antibiotic medicines currently in use block bacterial ribosomes from action.

The synthesis of the three types of ribosomes and their assembly could theoretically happen in various locus.

Ribosomes are the workbench of protein synthesis .

Without working ribosomes, bacteria cannot survive.

This inhibited the process of translation, producing a homogeneous population of empty ribosomes.

Ribosomes produce proteins, which in turn control the chemistry in all living organisms.

Numerous ribosomes, plastids and mitochondria were found in the cytoplasm of sporogenous cells.

Ribosomes are composed of long chemical chains, called ribonucleic acids (RNA), and proteins.

Each Nobel Prize winner showed how ribosomes tie or bind with antibiotics.

Many of today's antibiotics cure various diseases by blocking the function of ribosomes in bacteria.

The RNA messenger molecules relay them to structures known as ribosomes that read them and make proteins accordingly.

And normal ribosomes can't read mirror RNA or string together mirror amino acids.

Szostak hopes that even attempting to make mirror life could lead to a better understanding of how ribosomes work and cells evolved.

Ribosomal RNA (rRNA) -- the RNA component of ribosomes.

This year's Nobel Prize in Chemistry went to three molecular biologists who study ribosomes, the protein factories within cells.

As ribosomes are crucial to life, they are also a major target for new antibiotics.

Fig. 1 Boot stage, note the swollen plasmodesmata and numerous ribosomes.

This is why ribosomes are such an important target for new antibiotics.
