In general programming language, a Lambda expression (or function) is ananonymous function, i.e., afunction without any name or identifier, and with a list of formal parameters and a body. An arrow (->) is used to separate the list of parameters and the body. ...
There are three components in Lambda expression, The first component is surrounded by parentheses is an argument list, which can have none, one, or multiple arguments. The second component is Arrow-Token which can be used to connect the list of arguments with the body of expression. ...

The expression of the GOI from promoter pR is negatively regulated by the lambda CI[Ts] repressor binding to the wild type oR operator sites overlapping pR. These plasmids do not contain the oL operator sequences so that the tightest repression of transcription from the pR promoter, requiring ...
