Try these five self-checking multiple choice questions over gene regulation and mutation.

Once a gene has been located and transcribed into mRNA, it must first be edited before it can be translated into a protein. This editing process is called splicing it involves removing non-coding regions called "introns", leaving only...

[Free Registration/Login may be required to access all resource tools.] Gene expression is the use of a gene whose product is necessary for that moment. Whenever a particular protein is needed, gene expression provides it. This module...
