These capped snRNAs play important roles in the processing of nuclear precursor mRNAs and precursor rRNAs (reviewed in Busch et al. 1982; Brunei et al. 1985; Green 1986; P

Moghazyructure of immunoglobulins consists of two light and two heavy chains linked by interchain disulfide bonds (., 1959, 1969; . and ., 1967; ., 1968; . and ., 1969; . and ., 1970). In the most common class of immunoglobulins, IgG., the protein is a monomer with a molecular weight of 145,000 to 160,000.
