The low status of smell in Western culture is reflected in our language: colloquial terms for ânoseâ, for example, are almost all derogatory, or at the very least disrespectful (schnozzle, conk, hooter, snoot, snout, etc.) â and large or distinctive noses are considered ugly.
Ribosomes are organelles composed of ribosomal proteins (riboproteins) and ribonucleic acids (ribonucleoproteins). The word ribosome is made from taking â ribo â from ribonucleic acid and adding it to â soma â, the latin word for body. Ribosomes are bound by a membrane but they are not membranous.
Ribosomes can either be free ribosomes in the cytoplasm of the cell or they may find that the mRNA they are translating has a specific destination. In this case, some ribosomes will attach themselves to another cellular structure, and this is called the endoplasmic reticulum.Here, these are called the bound ribosomes.ibosomes are composed of two different subunits, called the large subunit and the small subunit. Both subunits are composed of rRNA and protein. These subunits usually exist separately in the cytoplasm until the small subunit recognizes and binds to a specific sequence of an mRNA message.
