If we inserted an anabolic Tryptophan (trp) operon with GFP for amino acid synthesis instead, what would happen if we grew the b
nignag [31]

Answer:

Since there is presence of excess tryptophan, the trp operon will be switched off, since the bacterial need not to synthesize.

Explanation:

Understand the following.

The trp operon is a group of gene that encode biosynthetic enzymes for the amino acid tryptophan.

The transcription gene in the operon is switched off when the tryptophan is in excess but is switched on by the bacterium when the tryptophan is low, so that more tryptophan can be produced.

Briefly explain what happens in each of the two stages of photosynthesis.
katrin2010 [14]
Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.

Answer:

Mutations are errors in genetic information and code that cause physical and functional alterations in living organisms. Some of them may be beneficial, harmful, or not produce significant alterations (neutral).

Explanation:

When categorizing each mutation as beneficial, harmful, or neutral, it's observed that:

A mutation in the HBB gene, which codes for  hemoglobin, produces red blood cells that  are rigid and sickle-shaped  and <u>is harmful</u>.

Sickle cell anemia is caused by the HBB gene mutation, producing crescent-shaped cells, or "YES", which are not functional and very short-lived, causing hemolytic anemia. Deformity in red blood cells can cause blockage of small-caliber arteries, causing other symptoms other symptoms related to the disease.

A mutation in the EYCL3 gene, which helps  regulate eye color, produces two  different colored eyes, is <u>neutral</u>.

Under normal conditions, EYCL gene determine the color of the eyes. A mutation of this gene can cause the same individual to have a green and blue eye, which is not a serious health problem, but rather aesthetic.

A mutation in the CFTR gene, which codes  for a cell transport protein, causes a buildup  of a thick mucus that covers the organs, which represents a <u>harmful</u> mutation.

Cystic fibrosis, a disease caused by a mutation in the CFRT gene, produces the excessive thick mucous secretion that lines up the lungs and other organs - liver, pancreas, intestine - that characterizes this condition.This causes a functional alteration of the affected organ. It is also known as mucoviscidosis.

A mutation in the LRP5 gene, which codes  for a cell membrane protein, increases  bone density, which<u> can be harmful</u>, when it produces symptoms or beneficial.

Increased bone density is called osteopetrosis, and depends on the LRP5 -Low density lipoprotein receptor-related protein 5- gene mutation, that can cause bone pain in childhood and adolescence in just over half of patients, but represents an increase in bone resistance and reduces the risk of fractures.
