<u>Answer</u>: Option D. RNA polymerase.
<u>Explanation</u>:
- Transcription is the process which is used to produce RNA from a DNA template.
- The enzyme involved in the process of transcription is <em>RNA</em> <em>polymerase</em> which is responsible for separating the DNA strands and making an RNA which is complementary to the DNA.
- RNA polymerase joins the nucleotides in the newly formed RNA strands by utilizing the energy released from the cleavage of the additional phosphate bonds that are removed by it.
- The RNA polymerase dissociates from the DNA only after the process of transcription is complete.

Answer:
e. unique three-dimensional shape of the fully folded polypeptide.
Explanation:
The tertiary structure of a protein is the unique three-dimensional structure which emanates from the interaction between the “R groups” of the several amino acids that make up the polypeptide. Hydrogen bonding is one of the interactions that occur that gives the protein this structure. Other interactions are ionic bonding, dipole-dipole interactions, hydrophobic interactions, among others. The function of a protein is dependent on its tertiary structure, as a disruption of the tertiary structure causes a protein to be denatured, thereby rendering the protein not functional.
Answer:
The given statement is true.
Explanation:
Alpha- defensins belong to the family of mammalian defensin peptides that belong to the alpha sub family. Defensins are anti-microbial molecules . They work against Gram positive and Gram negative bacteria, fungi and enveloped viruses. Alpha- defensins functions by attacking the intraluminal bacteria and fungal pathogens.
Reactive oxygen species are very reactive chemicals formed from oxygen. These are anti-microbial molecules. Reactive oxygen species are antimicrobial against Gram-positive and Gram -negative bacteria, viruses and fungi.
