Ribosome - the cytoplasmic organelle that translates the mRNA into the protein product specified by that mRNA.

Ribosomes are made up of rRNA(ribosomal RNA) and r Proteins (riosomal proteins).

Each ribosome has two subunits - a larger one and a smaller one. The subunits associate to form a complete ribosome during the initiation of translation and the subunits dissociate at the end of translation.

Bacterial ribosome has a size of 70s. Its small subunit has a size of 30s, which is made up of 16srRNA and 21 r proteins. The large subunit has a size of 50s. It components are 23srRNA, 5srRNA and 31 r proteins.

Eukaryotic ribosome is 80s in size with small subunit (40s) made up of 18srRNA and 33 r proteins and a large subunit (60s) made of 28srRNA, 5.8srRNA , 5srRNA and 49 r proteins.

Bacterial cells couple the process of transcription and translation. In eukaryotic cells, the process of transcription and translation are uncoupled or occur separately. Provide explanations as to why bacterial cells can couple the process of transcription and translation while in eukaryotic cells, the process is separated.

Very carefully read the following data requirements for a prospective document translation database: i. Document translation initially relies on a source document. The source document is a text provided in the originally recorded, valid language (see below, and assume only one language for the original document), and has an associated author and publication date. Source document authors are not related to translators in any manner. ii. Translation of a document also relies on a translator, who is capable of translating...

Transcription, translation and cell signaling within cells is controlled by many different mechanisms. Explain what each of these does to regulate the production of proteins: small interfering RNA(or siRNA), RNA splicing, and repressors(in operons). Please be specific and thorough as possible, I will give a thumb up if I like your answer. Thank you.
