Polyribosomes are aggregates of
ribosomes and rRNA
only rRNA
peroxisomes
several ribosomes held together by string of mRNA.
Plasma membrane is made of
proteins and carbohydrates
proteins and lipids
proteins, lipids and carbohydrates
proteins, some nucleic acid and lipids.
Organelles can be separated from cell homogenate through
chromatography
x-ray diffraction
different centrifugation
auto-radiography.
According to fluid mosaic model, plasma membrane is composed of
phospholipids and oligosaccharides
phospholipids and hemicellulose
phospholipids and integral proteins
phospholipids, extrinsic proteins and intrinsic proteins.
