VNTRs represent

Options

A. New terminal regions in DNA
B. Function genes in DNA
C. Split genes in sample DNA
D. Specifi non-coding sequencies with unique tandem repeats

Answer

**Step-by-Step Solution:**

1. **Understanding VNTRs**: VNTR stands for Variable Number of Tandem Repeats. This is the first step in answering the question, as it is essential to know what VNTRs are.

2. **Definition of Tandem Repeats**: A tandem repeat is a short sequence of DNA that is repeated in a head-to-tail manner. This means that the same sequence is repeated consecutively.

3. **Location in the Genome**: VNTRs are found at specific chromosomal loci in the human genome. This means that they are located at particular positions on chromosomes.

4. **Characteristics of VNTRs**: VNTRs can vary in the number of repeats among individuals, which is why they are termed "variable." Some sequences may be found at only one site (single locus) in the genome.

5. **Identifying the Correct Answer**: The question asks what VNTRs represent. Among the options given, the correct answer is "specific non-coding sequence with unique tandem repeats." This is because VNTRs are indeed non-coding sequences and consist of unique tandem repeats.

6. **Final Answer**: Therefore, VNTRs represent "specific non-coding sequence with unique tandem repeats."
