Answer :
Final answer:
Argonaute is the protein found in the RITS complex, which is involved in RNA-induced transcriptional gene silencing.
Explanation:
The protein that would be found in the RITS complex (RNA transcriptional silencing) is c) Argonaute. RITS is known for being involved in the RNA-induced initiation of transcriptional gene silencing. RITS contains small interfering RNAs (siRNAs) that are complexed with proteins including Argonaute, among others, which assist in targeting specific mRNA transcripts for silencing.
This is different from proteins like RNA polymerase, RNA helicase, and DNA ligase, which are involved in different aspects of DNA and RNA processing. In this context, the RITS complex specifically leverages the role of Argonaute in gene silencing.
