Question

Taylor's experiment involved analyzing the distribution of radioactive label in chromosomes during cell division.  This technique is most closely related to which field of study?

K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
	**Primary Concept**: Chromosome Structure and Function, Experimental Techniques in Biology
	**Related Topics**: DNA Replication, Cell Division (Mitosis and Meiosis), Radioisotopic Labeling
	**Prerequisites**: Basic understanding of cell biology and genetics.
## SOLUTION PATHWAY
**Given Information**:
	Taylor's experiment used radioactive labels to track chromosome behavior during cell division.
**Method & Steps**:
	1. **Understand the experiment's goal**: The experiment aimed to understand how chromosomes replicate and segregate during cell division.
	   Reasoning: By labeling chromosomes with radioactive material, researchers could visualize their movement and distribution.
	2. **Identify the core technique**: The use of radioactive labels to study biological molecules and processes is a key technique in molecular biology.
	   Key Point: Molecular biology focuses on the molecular mechanisms underlying biological processes, including DNA replication, gene expression, and protein synthesis.
	3. **Connect the technique to the field**:  Taylor's experiment directly investigates DNA and chromosome behavior at a molecular level, making it a molecular biology study.
	   Result: The correct field is Molecular Biology.
## OPTION ANALYSIS
[A] Cytogenetics :x: Cytogenetics studies chromosome structure and number, often using microscopy. While related, Taylor's experiment goes deeper into the molecular mechanisms of chromosome replication, which is the domain of molecular biology.
[B] Ecology :x: Ecology studies the interactions between organisms and their environment. This is completely unrelated to Taylor's experiment.
[C] Molecular biology ✓: Molecular biology is the study of biological activity at the molecular level. Taylor's experiment, focusing on DNA replication and chromosome behavior, falls squarely within this field.
[D] Paleontology :x: Paleontology studies fossils and ancient life.  This is unrelated to Taylor's experiment.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing cytogenetics with molecular biology: While both fields deal with chromosomes, cytogenetics focuses on larger-scale chromosome structure and abnormalities, while molecular biology delves into the molecular mechanisms involving DNA and related molecules.
	**Quick Tips**:
		1. Remember that techniques involving radioactive labeling to study biological molecules are typically associated with molecular biology.
