storing information permanently the way DNA does, in viruses. In non-viral cells, messenger RNA (mRNA) copies information from DNA and brings it to the cell's machinery for creating proteins, the ribosomes. Ribosomes use the information in RNA as...
which have cells that include a bare minimum of essential components: genetic material (i.e., DNA), a cell membrane to keep the whole thing together, cytoplasm (the gel-like matrix forming the majority of the cell's mass) and ribosomes, which manufacture proteins....
Smooth ER gets its name, as do so many things in anatomy and microanatomy, not from how it would really feel or taste but from its appearance. Because smooth ER does not have a high density of ribosomes (which appear dark on microscopy) embedded in its membranes, it looks like what it...
In the cytoplasm, ribosomes read the mRNA and assemble amino acids into protein. These proteins provide structure for the cell and allow it to do its job in the body. Proteins also give us our traits, from the color and texture of our hair to internal features like how fast we absorb ...
One solution to this question came from findings that mRNAs localized to distal dendrites and synapses [39], where their translation could be regulated by activity. These findings included detection of polyribosomes at the base of synapses as well as the identification of a subset of mRNAs that...
carrying the instructions for this process delivered by DNA. A second type of RNA, transfer RNA (tRNA), takes part in the manufacture of proteins. This occurs on cell organelles called ribosomes, and ribosomes themselves consist chiefly of a third type of RNA called, aptly, ribosomal RNA (...
One super cool note:the ribosomes of the rough endoplasmic reticulum aren’t permanently attached to the membrane itself.That means that new ribosomes can detach and attach depending on the proteins the cell needs! CFCF/Wikimedia Commons
