They do not have external ears like us. but they do have ear holes located directly behind their eyes. frogs ear holes are covered with thin tympanic membranes or the eardrums that protect the inner ear cavity.
The question is incomplete. The complete question is as follows:
Which of the following is most likely a product of an early gene?
A capsid proteins
B DNA polymerase
C envelope proteins
D spike proteins
E lysozyme
Answer:
DNA polymerase
.
Explanation:
Early gene may be defined as the gene that are activated immediately and the representation of this gene is important for the particular mechanism of the cell.
The DNA polymerase is the product of the early gene as the DNA polymerase is an important enzyme that are required for the DNA replication and can give immediate response to the different stimuli during the process of DNA replication.
Thus, the correct answer is option (B).
A nitrogenous base, or nitrogen-containing base, is an organic molecule with a nitrogen atom that has the chemical properties of a base. The main biological function of a nitrogenous base is to bond nucleic acids together. A nitrogenous base owes its basic properties to the lone pair of electrons of a nitrogen atom.
