Question

When Avery and McCarty were attempting to identify the substance involved transferring hereditary material, they tested the ability of a bacterial S cell extract to transform R cells after different components of the extract were degraded by enzymes. Which treatment inhibited the ability of the S cell extract to transform R cells

Answer 1

D). DNA degrading enzymes

Step-by-step explanation:

As per the question, the 'DNA degrading enzymes' is the treatment that has obstructed the S cell extract's potential to convert into R cells. The enzyme called 'deoxyribonuclease' functions to produce hydrolytic breakup that leads to the degradation of the DNA. It promotes the 'joining of the nucleotides to form the appropriate pairs by degenerating the molecules of the DNA that has pyrimidine dimers.' Thus, this is the reason due to which S cell is devalued before being transformed into the S cell as this DNase enzyme focuses on developing a new tract of efficient and correctly joined nucleotides. Hence, option D is the correct answer.
