Microarray in 'A' Level Biology

What is a microarray?

• A musical instrument used in the study of genes

• A type of microscope used to observe gene expression

• A type of small insect found in laboratories

• A laboratory tool used to detect the expression of thousands of genes at the same time

Explain the process of hybridization in microarray technology.

• In hybridization in microarray technology, the binding of DNA or RNA sequences to a solid surface is not necessary

• Hybridization in microarray technology is the process of amplifying DNA or RNA sequences using PCR

• The process of hybridization in microarray technology involves the binding of complementary DNA or RNA sequences to a solid surface, followed by detection and analysis of the bound sequences.

• The process of hybridization in microarray technology involves the use of magnetic fields to separate DNA or RNA sequences

What are the different types of microarrays used in biology?

• Inorganic microarrays, organic microarrays, and synthetic microarrays

• RNA microarrays, lipid microarrays, and carbohydrate microarrays

• DNA microarrays, protein microarrays, and tissue microarrays

• Cell microarrays, organ microarrays, and organism microarrays

How are microarrays used to study gene expression?

• By allowing researchers to simultaneously measure the expression levels of thousands of genes.

• By analyzing the DNA sequence of the genes

• By counting the number of chromosomes in the cell

• By measuring the size of the genes

Discuss the advantages and disadvantages of using microarrays in biological research.

• Microarrays provide limited gene expression analysis

• It is used to determine the impact of social media on cancer research

• It is used to study the effects of climate change on cancer cells

• It helps in identifying the best treatment for cancer patients

How does microarray technology contribute to the study of genetic diseases?

• It allows for the simultaneous analysis of thousands of genes, providing insights into the genetic basis of diseases.

• It is not a reliable method for studying genetic diseases

• It can only analyze a few genes at a time

• It has no impact on the study of genetic diseases

Discuss the ethical considerations related to the use of microarrays in genetic testing.

• Privacy, consent, discrimination, and psychological impact

• Cost, availability, accuracy, and speed

• Physical health, family history, blood type, and age

• Geographic location, education level, income, and employment status

Explain the future prospects of microarray technology in the field of biology.

• Microarray technology has no future in biology

• Microarray technology has a promising future in biology as it allows for the simultaneous analysis of thousands of genes, which can provide valuable insights into gene expression, genetic variation, and disease mechanisms.

• Microarray technology is too expensive and impractical for widespread use in biology

• Microarray technology is only useful for studying a small number of genes
