Determine the nature of the expression of the lacZYA genes, represented by L, and label each genotype as constitutive, inducible, or no transcription in the presence of lactose. Assume that all promoters are wild type. Symbol Representation I− lacI mutant cannot bind to the operator IS lacI mutant always binds to the operator OC Operator mutant that prevents repressor binding F' the wild‑type operator, O+, and lacI gene on a plasmid L lacZYA genes

Membrane vesicles containing an internal sodium chloride (nacl) concentration of 0.14 m are placed into separate beakers each containing a different solution. the first beaker contains 0.14 m sucrose, while the second beaker contains 0.14 m calcium chloride (cacl2). the temperature is 25°c. what is the solute potential inside the vesicles, expressed in units of mpa?

In 1994, telomerase activity was discovered in human cancer cell lines. although telomerase activity is rarely present in human somatic tissue, this discovery indicated that humans do contain the genes for telomerase proteins and telomerase rna. since inappropriate activation of telomerase may contribute to cancer, why do you think the genes coding for this enzyme have been maintained in the human genome throughout evolution?
