Ribosomal in Biological Definition

Ribosome

... of rRNA (synthesized in the nucleolus ) and 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 ribosomal subunits of prokaryotes and eukaryotes are quite ...

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 . Chromosomes in different species Table 1: Examples of chromosome numbers (diploid). Species # of chromosomes ...

Fungus

... 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 ...

Promoter

... promoter Transcription Start Site (TSS) Approximately -35 A binding site for RNA polymerase RNA-polymerase I: transcribes genes encoding ribosomal RNA RNA-polymerase II: transcribes genes encoding mRNA and certain small nuclear RNAs RNA-polymerase III: transcribes genes encoding tRNAs and ...
