1 / 1 point

True

False

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

Question 2

Electropolation is usually used for modifying the chloroplast genome.

1 / 1 point

True

False

Bolistic delivery via gene guns are usually used for modifying the chloroplast genome.

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

Question 3

What is synthetic biology?

1 / 1 point

Study of molecular pathways

Study of genomics and proteomics

A set of genetic tools

Construction of new biological systems

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

Question 4

What is bio-prospecting?

1 / 1 point

Breeding two species together to get a desired phenotype.

Adding multiple species to an environment and choosing the species that thrives.

Isolating algal strains from the wild.

Choosing an algae species (or any other biological organism) that will maximize output and profit.

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

Question 5

What is gene shuffling?

1 / 1 point

Using sexual recombination to change the position of genes in a single cell.

Exposing cells to a mutagen to create random changes in the genome.

Inserting genes from another species to create desired mutations.

Randomly combining many species in an environment to have a random and diverse gene pool.

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

Question 6

A flow cytometer and a cell sorter are used for single cell isolation during breeding selection.

1 / 1 point

True

False

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

Question 7

Cyanobacteria are prokaryotic, meaning they do not have a nucleus.

1 / 1 point

True

False

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

Question 8

Scientific evidence suggests that cyanobacteria are the evolutionary precursors to algal and terrestrial plant chloroplasts.

1 / 1 point

True

False

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

Question 9

Cyanobacteria can undergo gene conjugation, meaning they get genes from the environment.

1 / 1 point

True

False

They can undergo conjugation, but this is the process of gaining genes from other microbes.

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

Question 10

Why are some genetic tools for cyanobacteria not universal?

1 / 1 point

Not a lot of cyanobacteria species’ genomes have been sequenced.

Genetic tool development for cyanobacteria is still in its infancy.

Cyanobacteria have encoded defense systems to prevent exogenous gene modification.

The GC content of the genomes are quite difference across species.

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

Question 11

Algae chloroplasts have a complete genetic system.

1 / 1 point

True

False

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

Question 12

Gene expression in chloroplast is primarily controlled during transcription.

1 / 1 point

True

False

It is controlled during translation.

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

Question 13

The type of promoter used during genetic engineering of chloroplast has a large effect on how much recombinant protein is expressed.

1 / 1 point

True

False

The 5 prime untranslated region has a large impact.

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

Question 14

Complex systems, such as photosynthesis, can be synthetically engineered in the chloroplast.

1 / 1 point

True

False

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

Question 15

All amino acids are encoded by a single unique combination of three nucleotides called “codon”.

1 / 1 point

True

False

The same codon will always encode for the same amino acid, but each amino acid can be encoded by different codons as is represented in the codon table.

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

Question 16

The majority of genes in green algae are found in their nuclei.

1 / 1 point

True

False

Over 99% of their genes are in the nucleus.
