1. A type of cell called a lymphocyte makes proteins that are exported from the cell. You can track the path of these proteins within the cell from production through export by labeling them with radioactive isotopes. Identify which of the following structures would be radioactively labeled in your experiment, […]

Q. In bacteria, genes within an operon are transcribed under the control of a single promoter and the primary mRNA transcript contains sequences which can be translated into each of the independent proteins. In some cases the first gene in the linear sequence appears to be transcribed at a much […]

Explain why the choanoflagellates and the green algae are of evolutionaryimportance. describe the how an integral protein orglycoprotein becomes part of the plasma membrane. Describe the steps involved from protein formation in the rough ER to itsincorporation into the plasma membrane. Describe the organellesinvolved in the process and what they […]

An ac generator consisting of a coil with N turns rotating at angular speed “w” in an external magnetic field B produces a maximum emf E0. If you now decrease the number of turns in the coil to N/2 and at the same time cause it to rotate twice as […]
