Question 1

Which of the following are ways to transform genes in diatoms?

1 / 1 point

Electroporation

Particle bombardment

Bacterial conjugation

Cross-barrier intersection

==========================================

Question 2

What is used for DNA insertion through conjugation in diatoms?

1 / 1 point

E. Coli

Viral vectors

Tungsten particles

Gold particles

==========================================

Question 3

The first picture is a diatom grown in a nitrogen free environment, and the second is showing one grown in a nitrate environment. What does the green color indicate?

1 / 1 point

A green fluorescent marker shows the expression of a gene in the nitrate environment

The cell cytoplasm reacts to nitrate with a green color

This diatom species has a green chloroplast

This algal species has a green morphology

==========================================

Question 4

What is RNA translated into?

1 / 1 point

Proteins

Lipids

Sugars

Triacylglycerides

==========================================

Question 5

Thioesterase from vascular plants made the C. Reinhardtii algae produce as much fatty acids as endogenous thioesterase.

1 / 1 point

True

False

There was a specific protein interface interaction that made only endogenous thioesterase effective at increasing fatty acids in C. Reinhardtii.

==========================================

Question 6

What molecules are targeted for biofuel production in microalgae?

1 / 1 point

Proteins

Lipids

Carbohydrates

Amino Acids

==========================================

Question 7

Which of the following are reasons that a genetically-engineered algae may have low yields of a bioproduct?

1 / 1 point

Carbon or other resources are not flowing through the metabolic pathway of the bioproduct

Low expression levels of proteins that enable the bioproduct

Toxicity of the bioproduct or an intermediate to the algae

The bioproduct is not compatible with the particular strain of algae

==========================================

Question 8

Metabolic engineering is altering an organism’s flow of ______ towards a desired end product.

1 / 1 point

Lipid

Chlorophyll

Oxygen

Carbon

==========================================

Question 9

After sequencing the RB-TnSeq Library to identify the locations of transposon insertions, large segments of the genome that lack any transposon insertions indicated what?

1 / 1 point

The gene insertions were inconsistent across organisms.

These parts are unable to be sequenced.

These parts have gene function that are unknown.

These parts are essential gene regions.

==========================================

Question 10

It is not useful to remove essential genes in metabolic engineering.

1 / 1 point

True

False

These are essential and if removed would kill the organism.
