input: OPTIONS:
- resting
- gap
- mitosis
- synthesis Now, answer this question: Answer the following question given this paragraph: 9.2 | DNA Replication By the end of this section, you will be able to: Explain the process of DNA replication Explain the importance of telomerase to DNA replication Describe mechanisms of DNA repair When a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis. The elucidation of the structure of the double helix provided a hint as to how DNA is copied. Recall that adenine nucleotides pair with thymine nucleotides, and cytosine with guanine. This means that the two strands are complementary to each other. For example, a strand of DNA with a nucleotide sequence of AGTCATGA will have a complementary strand with the sequence TCAGTACT (Figure 9.8). Q: During which phase does dna replication occur in the cell cycle? A:
A:
output: synthesis

input: OPTIONS:
- soluble compound
- alloy
- magnetic compound
- ionic compound Now, answer this question: Answer the following question given this paragraph: There are many other examples of redox reactions in which two neutral elements combine to make a compound. These often take the form of a metal being oxidized and a nonmetal being reduced, resulting in an ionic compound. Two nonmetallic elements can also undergo a redox reaction of this type, in which the less electronegative element is oxidized and the more electronegative element is reduced. Q: When a metal is oxidized and a nonmetal is reduced in a redox reaction, what is the resulting compound called? A:
A:
output: ionic compound

input: OPTIONS:
- ions
- electrons
- protons
- neurons Now, answer this question: Answer the following question given this paragraph: Figure 3.9 (a) A typical human brain weighs about 1.5 kg and occupies a volume of roughly 1.1 L. (b) Information is transmitted in brain tissue and throughout the central nervous system by specialized cells called neurons (micrograph shows cells at 1600 magnification). Specialized cells called neurons transmit information between different parts of the central nervous system by way of electrical and chemical signals. Chemical signaling occurs at the interface between different neurons. Q: What are the specialized cells within the brain called? A:
A:
output:
neurons
