Show transcribed image text A IRNA with the anticodon 3' -ACC-5' would carry the amino acid: A) Phenylalanine. B) tyrosine. C) serine. D) threonine. E) tryptophan. We have learned the following concepts/terms (a-h) in the regulation of the lac operon. For statements 1-4, match each statement to the correct concept(s) or term(s). Not all letters need be used. Some letters may be used more than once. Concepts a. Allosteric transition b. Catabolite repression c. Negative control d. Inducible e. Cis-acting f. Trans-acting g. Constitutive h. Dominant (1) Phenotype of I^+ O^+ Z^-/I^+ O^C Z^+ (2) Phenotype of I^+ O^+ Z^-/I^- O^+ Z^+ (3) A lack of lac genes expression in the absence of lactose. (4) The Repressor protein, once binds lactose, no longer binds to the operator 24. The basic subunit of chromatin is Certain regions of a chromosome are always tightly packaged into heterochromatin, examples of such constitutively heterochromatic regions are and 25.Not all genes in cuchromaic regions are expressed. Propose two possible reasons for a " gene within euchromatin to be inactive (not expressed)? (Only consider the wild-type situation – no mutation involved – please.)
