(C) both cure and prevent disease among entire population of animals.
Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
I hope that it is correct
<h2>B) option is false</h2>
Explanation:
All events of cell cycle is regulated by a heterodimeric protein complex called cyclin CDKs, cyclin is the regulatory subunit which binds to CDKs and activate them whereas CDKs(cyclin dependent kinases) is the catalytic subunit where cyclin bound CDKs become active and act as serine threonine kinase and phosphorylate target proteins
The activation of S-Cdk helps prevent the onset of M phase because S phase cyclin CDK complex trigger initiation of DNA replication from pre replication complex and inhibits rebinding of components of pre replication complex
