Answer:  Option C - Supervision of insurance companies

Explanation:

• SEBI, the regulatory body in India for the securities market, primarily oversees activities related to securities, such as stocks, bonds, and mutual funds.
• While it regulates various entities like stock exchanges, mutual funds, and credit rating agencies to ensure fair and transparent markets, the supervision of insurance companies falls under the jurisdiction of the Insurance Regulatory and Development Authority of India (IRDAI).

Answer:  Option C - Managing risks associated with trades

Explanation:

• Clearing organizations play a crucial role in managing counterparty risk by ensuring the completion and settlement of financial transactions.
• They act as intermediaries between buyers and sellers, guaranteeing the integrity and efficiency of the trading process in financial markets.
• Facilitating stock exchanges: While clearing houses are connected to exchanges, their role isn't directly facilitating the exchange itself.
• Monitoring commodity prices: Clearing houses aren't typically involved in price monitoring, although they might deal with commodity futures contracts.
• Regulating corporate mergers: Mergers are a separate process from daily trading activities that clearing houses handle.

Answer:  Option D - siRNA

Explanation:

• While messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA) are integral to protein synthesis, small interfering RNA (siRNA) functions in RNA interference, regulating gene expression post-transcriptionally.
• Unlike mRNA, tRNA, and rRNA, siRNA targets mRNA for degradation, influencing gene expression.
• Understanding the distinctions between these RNA types elucidates their diverse roles in cellular processes, vital for comprehensive comprehension of molecular biology.

Answer:  Option A -  Adenine-Thymine-Guanine-Cytosine

Explanation:

• The correct sequence of nitrogenous bases in a DNA molecule is Adenine-Thymine-Guanine-Cytosine.
• Option A is correct. In DNA, adenine pairs with thymine, and guanine pairs with cytosine.
• This complementary base pairing is essential for the structure and function of DNA, enabling accurate replication and transmission of genetic information.

Answer:  Option D - Cell wall composition

Explanation:

• Bacteria are primarily characterized by their cell wall composition, which typically contains peptidoglycan.
• This feature distinguishes them from other organisms, such as eukaryotes, which lack peptidoglycan in their cell walls.
• While nucleic acid structure, cellular organization, and mode of reproduction vary among different organisms, it is the presence of peptidoglycan in the cell wall that is unique to bacteria and serves as a key identifying trait.
