Question

The sequencing of whole set of genome containing all the coding and non-coding sequences is referred as

• A. Sequence annotation
• B. Single nucleotide polymorphism
• C. Expressed sequence tags
• D. Restriction fragment length polymorphism

Hint:

Sequence annotation involves marking the regions of the genome that are involved in various biological functions, such as genes, regulatory elements, and non-coding regions.

Answer 1

The Correct Option is A

Genome Sequencing and Related Terms

• Sequence Annotation: This refers to the process of identifying and marking functional elements within a genome, including both coding (genes) and non-coding regions. It involves determining the locations of genes and their functions. Correct.
• Single Nucleotide Polymorphism (SNP): This refers to variations in a single nucleotide that occur at specific positions in the genome. It is a type of genetic variation but does not involve sequencing the entire genome. Incorrect.
• Expressed Sequence Tags (ESTs): These are short sequences derived from mRNA that represent expressed genes in a genome. They are used for gene discovery but do not cover the entire genome. Incorrect.
• Restriction Fragment Length Polymorphism (RFLP): This is a method used to analyze genetic variation by detecting differences in DNA fragment sizes after digestion with restriction enzymes. It is not related to sequencing the entire genome. Incorrect.

Conclusion: The correct answer is Option A, which refers to Sequence Annotation.
