A The codon AUG both codes for methionine and serves as an initiation site: the first AUG in an mRNA's coding region is where translation into protein begins.

Famous quotes containing the word table:

    “Remember thee?
    Ay, thou poor ghost, whiles memory holds a seat
    In this distracted globe. Remember thee?
    Yea, from the table of my memory
    I’ll wipe away all trivial fond records,
    All saws of books, all forms, all pressures past
    That youth and observation copied there,
    And thy commandment all alone shall live
    Within the book and volume of my brain,”
    —William Shakespeare (1564–1616)
