2. Suppose the DNA molecule were composed of six monomers. In addition to the monomers A, T, C and G, two other monomers, O and P, were present. Furthermore, O and P were known to pair only with each other. Which of following statements regarding this kind of DNA molecule would be accurate?

a. A DNA molecule composed of six monomers could not replicate.

b. If these two additional monomers were present, the DNA molecule would NOT be a polymer.

c. A DNA molecule composed of six monomers would carry less information than one composed of four monomers.

d. A DNA molecule composed of six monomers could replicate.

e. A DNA molecule composed of six monomers would carry the same amount of information as one composed of four monomers.

To determine which statement is accurate regarding a DNA molecule composed of six monomers, let's analyze each option:

a. A DNA molecule composed of six monomers could not replicate.
To determine if DNA replication is possible with six monomers, we need to examine if they can form complementary base pairs. In this case, O and P can only pair with each other, so replication could still occur. Therefore, option a is not accurate.

b. If these two additional monomers were present, the DNA molecule would NOT be a polymer.
A polymer is a large molecule composed of repeating subunits called monomers. Since a DNA molecule with six monomers still follows this pattern, it would still be considered a polymer. Thus, option b is not accurate.

c. A DNA molecule composed of six monomers would carry less information than one composed of four monomers.
The amount of information carried by a DNA molecule is determined by the sequence of its monomers, not the number of monomers. Regardless of whether there are four or six monomers, the information content depends on the arrangement of A, T, C, G, O, and P. Therefore, option c is not accurate.

d. A DNA molecule composed of six monomers could replicate.
As mentioned earlier, replication is possible as long as the monomers can form complementary base pairs. Since O and P can pair with each other, it is possible for the DNA molecule to replicate. Thus, option d is accurate.

e. A DNA molecule composed of six monomers would carry the same amount of information as one composed of four monomers.
As explained in option c, the amount of information is determined by the sequence, not the number of monomers. So, whether there are four or six monomers, the amount of information carried by the DNA molecule would depend on their specific arrangement. Therefore, option e is not accurate.

Based on this analysis, the accurate statement is:

d. A DNA molecule composed of six monomers could replicate.

i think the correct answer would be b
