Hershey and chase set out to determine what molecule served as the unit of inheritance. they completed a series of experiments in which e. coli was infected by a t2 virus. which molecular component of the t2 virus actually ended up inside the cell? a) proteinb) rnac) ribosomed) dna

The correct option is D.

Explanation:

In the year 1952, two scientists, Hershey and Chase conducted a series of experiments that helped to establish the fact that DNA is a genetic material. The DNA is located inside the nucleus of living cells in form of chromosomes and its the determinant of traits that are found in living organisms. During protein synthesis, the information in the DNA molecule is encoded into an RNA molecule and this is used in the production of protein, thus, DNA actually directs all the happen in the living cells.  

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.
