CLP 8 EN Exam

Ecometabolomics analyzes the metabolome, the total number of metabolites and their changes in response to environmental changes.

TRUE

FALSE

Which statement best describes the essence of environmental bioinformatics?

Using computer games for biology education

Using DNA to create new chemical elements

Using satellites to monitor the social behavior of animals

Integrating biological and environmental data through computational methods

Gene expression information in a given environmental sample is obtained by capturing total microbiome mRNA and performing comprehensive metatranscriptomic sequencing.

TRUE

FALSE

The catastrophic 2010 Deepwater Horizon oil spill in the Gulf of Mexico led to the activation of natural microbial communities with oil-degrading capacity. To identify the key bacteria responsible for natural bioremediation, scientists used:

Metagenomic and metatranscriptomic analyses

Proteomics and Metabolomics

Metabolomics and fluxomics

Metagenomics and Metabolomics

eDNA metabarcoding comprises taking environmental samples, extracting RNA, amplifying it through PCR with general or universal primers, and sequencing the amplification product through NGS to generate a huge amount of raw sequencing data.

TRUE

FALSE

Proteomics is the large-scale study of all proteins that are expressed at a given time by all organisms in an ecosystem.

TRUE

FALSE

What types of stressors affect environmental metabolomics?

Environmental metabolomics studies provide information on how organisms respond to various stressors, such as: water, air, and soil pollution; climate change, and natural disasters.

Toxins are stressors that affect environmental metabolomics.

Plants are stressors that affect environmental metabolomics.

Natural disasters are stressors that affect environmental metabolomics.

Environmental bioinformatics integrates biological data with environmental science.

TRUE

FALSE

Environmental bioinformatics helps in studying biodiversity and conservation.

TRUE

FALSE

Environmental DNA (eDNA) is:

The whole organismal nuclear or mitochondrial DNA

Organismal nuclear or mitochondrial DNA released in the environment
