Study Notes
Glycosidic Linkages in Cellulose and Amylose
- Cellulose and amylose are polysaccharides.
- Cellulose has β 1-4 glycosidic linkages.
- Amylose has α 1-4 glycosidic linkages.
Lac Operon and β-Galactosidase
- The lac operon regulates the breakdown of lactose in bacteria.
- A mutation in the operator locus of the lac operon can result in constitutive expression of β-galactosidase.
- A cis-dominant mutation affects only the allele on the same chromosome.
Identifying Points Above a Line
- The question requires identification of a point above a line.
- The provided points are: P = (3, 1/3), Q = (1/3, 1), R = (11/3, 1/3), and S = (11/3, 3).
- Information about the line is missing from the provided text.
