Meaning: a prefix used to make words with a sense opposite to that of the root word; in this case, meaning "without" or "-less". This is usually used to describe organisms without a certain characteristic, as well as organisms in which that characteristic may not be immediately obvious.
First, prefixes and suffixes, most of which are derived from ancient Greek or classical Latin, have a droppable vowel, usually -o-. As a general rule, this vowel almost always acts as a joint-stem to connect two consonantal roots (e.g. arthr- + -o- + -logy = arthrology ), but generally, the -o- is dropped when connecting to a vowel-stem (e.g ...

A feature affecting clarity in seeing a scientific word's components is haplology, i.e. removing one of two identical or similar syllables that meet at the junction point of a compound word. Examples are: appendectomy = appendix, appendicis, (Latin for "appendix") + -ectomy (ultimately from Greek τομή, "a cutting")
Adding a prefix to the beginning of an English word changes it to a different word. For example, when the prefix un-is added to the word happy, it creates the word unhappy. The word prefix is itself made up of the stem fix (meaning "attach", in this case), and the prefix pre-(meaning "before"), both of which are derived from Latin roots.
The word preposition comes from Latin: prae-prefix (pre- prefix) ("before") and Latin: ponere ("to put"). This refers to the situation in Latin and Greek (and in English ), where such words are placed before their complement (except sometimes in Ancient Greek), and are hence "pre-positioned".
The pre-mRNA processing at the 3' end of the RNA molecule involves cleavage of its 3' end and then the addition of about 250 adenine residues to form a poly(A) tail.The cleavage and adenylation reactions occur primarily if a polyadenylation signal sequence (5'- AAUAAA-3') is located near the 3' end of the pre-mRNA molecule, which is followed by another sequence, which is usually (5'-CA-3') and ...
