Answer:

B There will be blue colonies only

Explanation:

This screen in called the blue white screening. This is a rapid test that allows scientist to check for their insert of choice in the colonies at a glance. The concept is that where the insert is located the <em>lac Z </em>gene in the vector is interrupted and therefor Xgal, a reporter can be produced. Where there are blue colonies being formed the plasmid has self-ligated and the <em>lac Z</em> gene is not interrupted and the X-gal can be formed rendering a blue color.

Which best describes a disadvantage of this scenario?

Andre45 [30]

Answer:

Which best describes a disadvantage of this scenario?

Scientists have cloned goats so they can take out a

protein in the goats' milk and use it to make medicine.

The goats are raised in a laboratory. The medicine that

is produced can help with certain diseases that affect

humans.

O The goats will have more genetic variation

O The goats will become infected with the human

diseases.

There are unknown health risks to the goats.

O There could be many health risks to drinking the

goats' milkWhich best describes a disadvantage of this scenario?

Why do we want to turn genes off or on?

Dmitrij [34]

The process of turning off and on of genes is known as gene regulation.

Explanation:

When the gene is turned on, it instructs the cells to construct a particular protein. The proteins are the molecules that build your body with collagen, tendons, and bones or keratin in your hair.

The gene regulatory proteins allow the individual genes of an organism to be turned on or off . in different cell types there are different selections of gene regulatory proteins. The patterns of the gene expression gives each cell its unique characteristics.

Each cell produces or turns on only a fraction of its genes. the remaining genes are repressed or turned off. this process is known as gene regulation. The signals from the environment or from other cells activate proteins called transcription factors.
