Question

Question 12 12 points A doctor acquires genomic information from her patient. After examining the patient's sequence and inferring risk factors, she tells her patient that he has an elevated risk of acquiring prostate cancer and recommends an aggressive course of screening. This example characterizes a. pharmacogenomics b. metagenomics functional genomics d. personal genomics e comparative genomics.

Answer 1

Solution:

(1) Correct answer D-personal genomics

• Pharmacogenomic is field of genomic science in which genetic information is used to study drug action on the physiological functions.
• Personal genomics is field of genomic science ,which is focused on the sequencing and analysis of genome of an individual , and then providing them their genomic information based diagnosis.
• Metagenomics is the study of genetic material from from environment, community
• Functional genomics is a field of genomic science which involved in analysizing and describ gene (and protein) functions and interactions in cell.
• Comparative genomics is a field of genomic science in which the genomic features of different organisms are compared.

(2) Correct option C - the percentage of the genome devoted to coding sequences in eukaryotic genomes is lower than in prokaryotic genomes.

Eukaryotic genome	Prokaryotic genome
Nucleus is present	Nucleus absent
Multiple origin of replication in a chromosome	Single origin of replication
various types of regulatory sequences for controlling the gene expression	Lesser regulatory sequences
percentage of coding genome -about 1%	Percentage of coding genome more that 85%
Have transposons	Have transposons
Larger genome	Smaller genome

(3) Correct option E -Microarray analysis

• Pharmacogenomic is field of genomic science in which genetic information is used to study drug action on the physiological functions.
• Metagenomics is the study of genetic material from from environment, community
• Functional genomics is a field of genomic science which involved in analysizing and describing a  gene (and protein) functions and interactions in cell.
• Comparative genomics is a field of genomic science in which the genomic features of different organisms are compared.
• Microarray analysis used to detect the expression of thousands of genes of a short DNA segment.and help in studying and investigating the expression of gene.
