If a geneticist uses the blind approach for sequencing the whole genome of an organism, followed by assignment of function to different segments, the methodology adopted by him is called as:
  • a)
    Gene mapping
  • b)
    Expressed sequence tags
  • c)
    Bioinformatics
  • d)
    Sequence annotation
Correct answer is option 'D'. Can you explain this answer?

Sequence annotation is the process of identifying and assigning functional information to different regions or segments of a sequenced genome. It involves analyzing the DNA sequence data and using various computational and experimental methods to identify genes, regulatory elements, non-coding regions, and other functional elements within the genome. This process helps in understanding the genetic makeup and potential functions of different parts of the genome.
Gene mapping is a different process that involves determining the physical locations of specific genes on chromosomes.
Expressed sequence tags (ESTs) are short DNA sequences derived from expressed genes, often used to identify and characterize genes that are actively transcribed.
Bioinformatics is the field of study that combines biology and computer science to analyze and interpret biological data, including genomic sequences.
Therefore, the correct answer is (d) Sequence annotation.

Sequence Annotation

Sequence annotation is the process of identifying the functional elements within a genome sequence. It involves assigning biological information to segments of DNA or RNA sequences, such as identifying genes, regulatory elements, and other functional elements.

Blind Approach for Sequencing the Whole Genome

The blind approach for sequencing the whole genome refers to the process of sequencing the entire genome of an organism without prior knowledge of the specific genes or functional elements present in the genome. This approach aims to obtain a comprehensive understanding of the genetic makeup of an organism.

Methodology Adopted by Geneticist

- The geneticist in this scenario first uses the blind approach to sequence the entire genome of the organism. This involves sequencing all the DNA or RNA present in the organism's genome.
- Once the genome is sequenced, the geneticist then proceeds to annotate the sequence by assigning biological functions to different segments of the genome.
- The geneticist identifies genes, regulatory elements, and other functional elements within the genome sequence using various bioinformatic tools and techniques.
- Bioinformatics is a field that combines biology, computer science, and statistics to analyze and interpret biological data, including genome sequences. The geneticist uses bioinformatics tools and software to analyze the sequenced genome and identify potential functional elements.
- The process of assigning biological functions to different segments of the genome is known as sequence annotation.
- Through sequence annotation, the geneticist gains insights into the genetic composition and functionality of the organism's genome.

Answer Explanation

The methodology adopted by the geneticist in this scenario is best described as sequence annotation. Gene mapping refers to the process of determining the physical location of genes on a chromosome, while expressed sequence tags (ESTs) are short DNA sequences derived from transcribed regions of the genome. Bioinformatics is a broader field that encompasses the use of computational tools and techniques to analyze biological data, including genome sequences. Sequence annotation specifically refers to the process of assigning biological functions to segments of a genome sequence, which aligns with the methodology described in the scenario.
