C) Western blotting
D) Eastern blotting
E) RT-PCR

Question

Quizplus · Accepted Answer

Western blotting is the transfer of protein sequences (not polypeptide sequences) from a gel to a membrane to analyze gene expression. It is used to detect the presence of proteins and their quantity in a sample. Southern blotting is used to detect DNA sequences, Northern blotting is used to detect RNA sequences, Eastern blotting is not a commonly used technique, and RT-PCR is a method for detecting and quantifying RNA.
