Human Genomics

Question 1

What is genomic sequencing?

Answer 1

A process in which the order of the nucleotide bases along an organism’s genome is determined

A genome consists of genes and other DNA sequences that do not code for proteins.

Question 2

What can the sequence of nucleotide bases help identify?

Answer 2

• Genes responsible for diseases
• Genome sequences for conditions
• Genomic mutations and variations

This identification is crucial for understanding genetic disorders.

Question 3

What is the role of bioinformatics in genomic analysis?

Answer 3

To compare sequence data

Analysis of the human genome is one of the main achievements of bioinformatics.

Question 4

What does the future of genomic analysis include?

Answer 4

• Enhanced use of targeted drugs
• Individualised therapy

A fuller understanding of how the human genome works is expected to lead to these advancements.

Question 5

How has the cost and time of sequencing an individual’s genome changed?

Answer 5

Sequencing is now cheap, quick, and can be done in days rather than years

This advancement makes obtaining an individual’s personal genome relatively easy.

Question 6

What can analysis of an individual’s genome predict?

Answer 6

The likelihood of certain diseases developing

This analysis can identify harmful or neutral mutations within the genome.

Question 7

What is personalised medicine?

Answer 7

Medicine tailored to the individual based on their genomic analysis

It uses pharmacogenetics to predict the success of treatments.

Question 8

What significant project was completed in 2003 related to the human genome?

Answer 8

The Human Genome Project

It sequenced three billion nucleotide bases and identified around 20,000 genes.

Question 9

How can personalised medicine assist in treatment selection?

Answer 9

By selecting the best drugs and dosage for a patient’s particular disease

This approach increases the likelihood of treatment success.
