Q1. Name two modalities of analysis following sequence.
Ans- The two modalities are De novo and genome guided modalities of analysis following sequence.
Q2. Name any three major types of variants.
Ans- The three major types of variants are:
1.) Single nucleotide variance.
2.) Insertions and deletions.
3.) Copy number variations.
Q3. What are disease- specific variants are termed as?
(a) Somatic.
Q4. Which is preferred tool for transcriptome assembly, in the de novo and genome guided modalities?
(b) Trinity.
Q5. What is difference between BLAT and BLAST?
Ans- BLAST is Basic Local Alignment Tool which search protein or nucleotide sequences and BLAT is BLAST- like alignment tool which stores the genome index in the memory.

Q7. Name any two of the major classes of biological macromolecules.
Ans- The two major classes of biological macromolecules are nucleic acids and proteins.
Q8. DNA sequences can be represented by which of the following data format?
(b) FASTA.
Q10. Which tool can help you visualize variants in circular manner?
(b) CIRCOS.
Q11. Which of the following approaches can help one in arriving at a comprehensive understanding of the biology of an organism?
(a) Single assay across multiple individuals.
Q12. Why do we need to sequence nucleic acids? What can one gain by understanding the sequence of nucleic acid?
Ans- We need to sequence the nucleic acid because we can know the structure of nucleic acid and the statistical data can be obtained by sequencing of nucleic acid. One can gain the knowledge about the nucleic acid and how the structure is present and also have the knowledge about the statistics of nucleic acid.
