The answer is b) False.

Explanation:

  • RNA is not limited only to storing genetic information. It plays several roles in the cell, including acting as a messenger (mRNA) that carries genetic information from DNA to the ribosome, where proteins are synthesized. RNA also plays structural and catalytic roles (rRNA and tRNA) in the ribosome and is involved in regulating gene expression (e.g., miRNA, siRNA).
  • DNA primarily serves as the storage of genetic information. It does not perform a variety of functions beyond this role. The variety of nucleic bases in DNA (adenine, thymine, cytosine, and guanine) is similar to that in RNA (adenine, uracil, cytosine, and guanine), but this does not inherently give DNA a broader range of functions.

In summary, RNA has multiple functions beyond storing genetic information, while DNA's primary role is to store genetic information.

A credit card company determines a card holder's minimum monthly payment by adding all new interest to 1.5% of the outstanding principal. The credit card company charges an interest rate of 0.05545% per day. On November 10, a customer used his credit card to pay for the following business expenses: van repairs (996), equipment maintenance (487), office supplies (72), and dinner with clients (155). Use the given information and the rule that minimum payments are rounded up to the nearest dollar to answer parts a and b below. a. Assuming the card holder had no new interest, determine his minimum payment due on December 1, his billing date. The card holder's minimum payment due on December 1 is square.
