Question 1:

What is comparative genomics?

Explanation: Comparative genomics is the study of similarities and differences in the genomes of different organisms. It involves comparing the DNA sequences, gene content, and genomic structures of different species to gain insights into evolutionary relationships and functional elements within genomes.

Question 2:

Which of the following is an application of comparative genomics?

Explanation: One of the applications of comparative genomics is studying the evolution of species. By comparing the genomes of different organisms, scientists can uncover evolutionary relationships, identify conserved genes, and understand the genetic changes that have occurred over time.

Question 3:

Which technique is commonly used in comparative genomics?

Explanation: Whole-genome sequencing is commonly used in comparative genomics. It involves sequencing the entire genome of an organism to obtain its complete DNA sequence. This enables researchers to compare genomes across different species and identify similarities and differences.

Question 4:

What can comparative genomics reveal about genes?

Explanation: Comparative genomics can reveal information about the function and evolutionary history of genes. By comparing the genomes of different organisms, scientists can identify conserved genes that have similar functions across species and gain insights into how genes have evolved over time.

Question 5:

Why is comparative genomics important?

Explanation: Comparative genomics is important because it provides insights into the evolution and function of genes. By comparing genomes, scientists can discover conserved genes, identify functional elements, and understand the genetic basis of traits and diseases across different species.
