When an antibiotic binds to bacterial ribosomes how specifically does that affect the bacterium?

the antibiotic binds to bacterial ribosomes when the antibiotic is taking to kill the bacteria, as the antibiotics is taking it bind to the smaller subunit of the bacterial ribosomes ,preventing the bacterium making new protein.

∙ 12y agoErythromycin interferes with translocation during elongation of protein synthesis because by binding to the 50S subunit it prevents the exit of the polypeptide chain out of the ribosome. This causes the short (6-8 amino acids long) unfinished chain to 'drop off' while still attached to the tRNA, preventing any further protein synthesis.

Do bacterial cells have ribosomes?
YES! Bacteria do have ribosomes. The ribosomes take about 30% of the whole bacterium's weight. Approximately 10,000 ribosomes are in one bacterium cell.Read more: http://wiki.answers.com/Does_bacteria_have_ribosomes#ixzz1MqAdy79v
Why do mitochondria have their own ribosomes?
They were evolved from bacteria.So they have bacterial ribosomes.
What does Chloramphenicol do?
Chloramphenicol is a broad spectrum antibiotic. It functions by inhibiting protein synthesis in bacterial cells by binding to the ribosome. The ribosomes of prokaryotic cells are 70S where as eukaryotes have 80S ribosomes, this fundimental difference means that chloamphenicol specifcally targets bacterial protein synthesis. It is effective against Gram positive as well as Gram negative bacteria.
Why do bacteria cells have ribosomes As in what do the ribosomes do?
The ribosomes in bacterial cells do the same job as ribosomes in human and animal cells; they are "sites of translation (protein synthesis)".
How does streptomycin kill bacterial cells?
Streptomycin is a protein synthesis inhibitor. It binds to the S12 Protein of the 30S subunit of the bacterial ribosome, interfering with the binding of formyl-methionyl-tRNA to the 30S subunit. This prevents initiation of protein synthesis and leads to death of microbial cells. Humans have structurally different ribosomes from bacteria, thereby allowing the selectivity of this antibiotic for bacteria. However at low concentrations Streptomycin only inhibits growth of the bacteria by inducing prokaryotic ribosomes to misread mRNA. It is an antibiotic that inhibits both Gram-positive and Gram-negative bacteria and is a therefore a useful broad spectrum antibiotic

What is the smallest ribosome mitochondrion virus bacterium or protein?
Ribosomes are the smallest between mitochondria, viruses, bacterium, and protein. Ribosomes are the building blocks of mitochondria, viruses, bacterium, and proteins.

What does ribosomes do in a bacteria cell?
A bacterial cell contains about 10,000 ribosomes which co up to 30% of the weight of the bacterium. In contrast to most eukaryote ribosomes, the bacterial ribosomes do not appear to be attached to internal cell membranes, but are found free in the cytoplasm. In functionally, active bacteria the cytoplasm is packed -with free and randomly distributed ribosomes. This dense packing may mask any attachment to internal membranes. Strings of ribosomes have been found loosely attached to the inside of the plasma membrane.

How is a chloroplast similar to bacterium?
They are similar in size.Both have own circular DNA.They have 70s ribosomes.
Are ribosomes present in bacteria?
True. The ribosomes are where polypeptides are assembled from amino acids. Bacterial (prokaryotic) ribosomes are smaller than eukaryotic ones.
Do plant and bacterial cells have ribosomes?
well no dur stupid
Is protein synthesis affected when a toxin destroys ribosomes?
Yes, very much so. Ribosomes in prokaryotes use a slightly different process to produce proteins than do ribosomes in eukaryotes. Fortunately, this difference presents a window of molecular attack by antibiotic drugs such as streptomycin.Unfortunately, some bacterial toxins and the polio virus also use it to enable them to attack thetranslation mechanism in our cells.
