ribosomal proteins. It translates mRNA into a ... of one or two very large RNA molecules (known as
ribosomal RNA or rRNA ) and multiple smaller protein ... expelled from the cell via exocytosis .
The

Antibiotic
... with bacterial protein synthesis
Antibiotics which bind to the 50S
ribosomal unit
Lincosamides/lincosides including clindamycin and lincomycin; chloramphenicol, macrolides
Antibiotics which interfere the 30S
ribosomal unit
Tetracyclines; aminoglycosides including gentamicin

Nucleolus
... of the cell nucleus , which is an organelle .
It is a consequence of
ribosomal RNA ( rRNA ) synthesis: nucleolar organizers , special regions on some ... synthesis, rRNA molecules are attached to proteins, forming
ribosomal subunits, which leave for the cytosol through nuclear pores .

RNA
... The best-known examples of RNA genes are transfer RNA ( tRNA ) and
ribosomal RNA ( rRNA ). Both forms participate in the process of translation , but ...
The most prominent examples of RNA genes are transfer RNA (tRNA) and
ribosomal RNA (rRNA), both of which are involved in the process of translation. ...
Biodiversity
... from Sean Nee
"the contribution of visible life to biodiversity is very small indeed".
"On the tree of life, based on analyses of small-subunit
ribosomal RNA , visible life consists of barely noticeable twigs. This should not be surprising — invisible life had at least three billion years to ...
Chromosome
... even if they are far apart on the chromosome. The short arm of a chromosome can be extended by a satellite chromosome that contains codes for
ribosomal RNA .

... taxa has undergone substantial changes in the last several decades, especially as techniques for comparing biochemical characteristics (such as
ribosomal RNA and DNA) have become increasingly more sophisticated. The phylogeny presented here is after Bruns et al. (1991, 1993) for the Eumycota (true ...
