When DNA ligase has compelted its job catalyzing the formation of a phosphodiester bond to bring together the backbone of two separate DNA strands and bind them together, the result is that two separate strands of DNA become one.
Science refers to the construction of knowledge by using the scientific method. This method is based on empirical evidence.
Science can be defined as the construction of knowledge (scientific knowledge) by using the scientific method.
The scientific method includes several sequential steps:
- Observation
- Ask questions
- Form a testable explanation (hypothesis)
- Test the hypothesis
- Collect results (empirical evidence)
- Draw conclusions
In the scientific method, empirical evidence can be used to support the working hypothesis.

Answer:
b. reducing molecules
Explanation:
Nicotinamide adenine dinucleotide (abbreviated NAD +, and also called diphosphopyridine nucleotide and Coenzyme I), is a coenzyme found in all living cells. The compound is a dinucleotide, as it consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and the other that contains nicotinamide.
In metabolism, NAD + participates in redox reactions (oxidoreduction), carrying electrons from one reaction to another.
Coenzyme, therefore, is found in two forms in cells: NAD + and NADH. NAD +, which is an oxidizing agent, accepts electrons from other molecules and becomes reduced, forming NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD +. However, it is also used in other cellular processes, especially as a substrate for enzymes that add or remove chemical groups of proteins, in post-translational modifications. Due to the importance of these functions, the enzymes involved in the metabolism of NAD + are targets for drug discovery.
