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 are typically composed of two subunits: a large subunit and a small subunit. 1  Ribosomal subunits are synthesized in the nucleolus and cross over the nuclear membrane to the cytoplasm through nuclear pores. These two subunits join together when the ribosome attaches to messenger RNA (mRNA) during protein synthesis. Ribosomes along with another RNA molecule, transfer RNA (tRNA), help to translate the protein-coding genes in mRNA into proteins.
