DNA polymorphism forms the basis of:a)DNA finger printingb)Both genetic mapping and DNA finger printingc)Translationd)Genetic mappingCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Explanation:

DNA Polymorphism:
- DNA polymorphism refers to the genetic variation that exists within a population.
- It can manifest as differences in the DNA sequence, such as single nucleotide polymorphisms (SNPs), insertions, deletions, or other structural variations.

Basis of DNA Fingerprinting:
- DNA polymorphism serves as the basis for DNA fingerprinting, a technique used to identify individuals based on their unique DNA profiles.
- By analyzing polymorphic regions of the genome, such as short tandem repeats (STRs) or variable number tandem repeats (VNTRs), specific patterns can be generated for each individual.

Genetic Mapping:
- Genetic mapping involves the identification of the location of genes and other DNA sequences on chromosomes.
- DNA polymorphisms are essential for genetic mapping as they provide markers that can be used to track the inheritance of specific traits or diseases within families.

Both Genetic Mapping and DNA Fingerprinting:
- Therefore, DNA polymorphism forms the basis of both genetic mapping and DNA fingerprinting.
- While genetic mapping focuses on understanding the genetic landscape of an organism, DNA fingerprinting is more concerned with individual identification and forensic applications.

In conclusion, DNA polymorphism plays a critical role in various areas of genetics and genomics, serving as a fundamental tool for understanding genetic diversity, inheritance patterns, and individual identification.

Answer

DNA polymorphism refers to variations in DNA sequence among individuals or populations. These variations can be used to differentiate individuals and analyze genetic relationships. Genetic mapping involves the identification and mapping of genes or genetic markers on chromosomes, and DNA polymorphisms are essential for creating genetic maps.

DNA fingerprinting, also known as DNA profiling or DNA typing, is a technique that uses DNA polymorphisms to identify and compare individuals based on their unique genetic profiles.

Therefore, both genetic mapping and DNA fingerprinting rely on DNA polymorphism as their basis.

The correct answer is option (2) Both genetic mapping and DNA fingerprinting.
