s stands for sedimentation coefficient defined as how fast a cell organelle sediment in ultra centrifuge . As sedimentation coefficient are not additive so that 50s plus30s is not equal to 80s but it is 70s[prokaryotic]

ribosomes are not cells, they are organelles that produce and synthesize proteins. get it straight!


What does kanamycin target?

the 30S subunit of the ribosome.


The sites A P and E are occupied by amino acids being assembled into a chain of polypeptide what are they part of?

The A, P and E sites are part of the prokaryotic ribosome, specifically, the 16S rRNA of its 30S subunit.


What two things make up ribosomes and are are ribosomes surrounded by membrane like other organelles?

A ribosome is a biological molecule made of ribonucleic acid (RNA) and proteins (ribosomal proteins). A ribosome is made of two pieces (subunits).A typical eukaryotic cell ribosome consists of two subunits named 60S (large subunit) and 40S (small). A prokaryotic cell ribosome is a little smaller but it is made of two subunits, too: a 50S and 30S subunit.No, it isn't surrounded by a membrane as some other organelles are.A ribosome is a biological molecule made of ribonucleic acid (RNA) and proteins (ribosomal proteins).A ribosome is made of two pieces (subunits).

What is the 30S and 50S?

The 30S and 50S are two subunits that form a ribosome in prokaryotes. The 30 and 50 denote the individual size of each part, and the 'S' stands for Svedberg unit.


What is a ribosome constructed of?


Why ribosomes are of 70s in mitochondria of eukaryotic cell?

Prokaryotes have 70S ribosomes, each consisting of a small (30S) and a large (50S) subunit.


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 0.66666 as a fraction?

The answer to 0.666666666 is equaled to 2/3 as a simplified fraction in thirds but if we wanted to know it in 30s it will equal 20/30.


What is meant by 16s rDNA?

Ribosomal 16S RNA found in the bacteria and small microorganisms prokaryotic cells and the subunit is 30S.


What is the small part of the nucleus where ribosomal subunit formation takes place?

The small unit found in ribosomes are called subunits. They are denoted according to their sedimentation coefficients in the Svedberg units. The 40S is the subunit for eukaryotic ribosomes, while the 30S is the subunit for prokaryotic ribosomes.
