Which of the following mutations would you expect to have the greatest effect on a living cell?
A)A mutation that changes a single base in a region of noncoding DNA
B)A mutation that changes the third letter of one of the three-base "words" in a particular gene
C)A mutation that deletes one base in the middle of a gene

Answers

Answer 1

C) A mutation that deletes one base in the middle of a gene would likely have the greatest effect on a living cell. This type of mutation can disrupt the reading frame of the gene, potentially altering the amino acid sequence of the protein it codes for and altering its function.

A mutation in a non-coding region of DNA would not have as much of an impact on a living cell as it would not affect the production of a protein. A mutation that changes one base in a codon would also have an effect, but it could be less severe than a frameshift mutation.

A gene is a specific sequence of DNA that codes for a specific protein. Proteins are important molecules that carry out various functions in the cell, such as catalyzing reactions, replicating DNA, responding to stimuli, and transporting molecules across cell membranes. The sequence of a gene is read in groups of three bases, called codons, which code for specific amino acids that are used to build the protein.

A mutation is a change in the DNA sequence that can occur spontaneously or be induced by environmental factors. Some mutations have no effect on the function of the protein, while others can alter its structure and function.

You are reviewing a skeleton with severe trauma to the left clavicle, left scapula, and left humerus. The skull is severely fragmented as well. You notice the clavicle is separated cleanly in half mid-diaphysis. Nearby, the anterior portion the scapula has a dramatic cleft that is straight margined on its left (lateral) margin and shows jagged fracture and wastage of bone on its right (medial) margin. It progresses a full inch and a half or more downward posteriorly. The Humerus has a deep lateral transverse incision with slight chipping, deeper in the posterior aspect than the anterior. The skull is highly fragmented and bears fractures radiating from straight margin sites of trauma. The causative wounds are medium in width (3.5 mm) but very long (one runs from the most superior aspect of the right parietal, through the entirety of the left parietal at a diagonal and exits the anterior/inferior left parietal with fragmentation/wastage there and a nearby notch on the superior left zygomatic. There are three blows to this side of the skull (left), the one described is clearly the largest. Its radiating fractures end in those of the others or in bone sutures of the vault creating large triangular or irregular fragments. These blows show some wastage, biased toward the anterior aspect of each, with no evidence of crushed margins, but instead coarse striations. Which two types of trauma are indicated? What does the nature of the wounds indicate might be a likely implement? What does the order of trauma indicate about the positioning of the perpetrator and victim in this context?

Answers

The type of trauma that are indicated are both complex and  chronic traumas.

What is trauma?

Trauma can be defined as the serious event that can negatively affect the emotional, physical and mental being of an individual.

From the excerpt given, the two types of trauma represented are:

Chronic trauma: This is the type of trauma that is severe or very serious. Example is the fragmented skull and separation of the clavicle neatly in half mid-diaphysis.

Complex trauma: This occurs when there is exposure to numerous events that causes trauma.

The nature of the wound indicates that the cause would be of direct force from blows.

The positioning of the perpetrator and the victim according to the order of the trauma is that both of them where involved in a fight.

2) _______________________________________________________________
3) _______________________________________________________________
4) _______________________________________________________________

4. Assuming that the mutations are adaptive, how should the changes that you identified affect the stability of the protein at low and high temperatures?

Answers

The amino acids that changed between the three species are;

Amino acid 151 transited from valine to isoleucine in a warm adapted species.Amino acid 201 translated from glycine to alanine in warm adapted species.Amino acid 201 morphed from glutamine to lysine in warm adapted species.Amino acid 201 translated from glutamic acid to aspartic acid in cold adapted species.

What were the changes in the chemical properties of the R-groups?

The changes in the chemical properties of the R-groups are given as:

Both valine and isoleucine are nonpolar.Both glycine and alanine are nonpolar.Glutamine is an uncharged polar group and Lysine is a charged polar group.Both glutamic acid and aspartic acid are charged polar group.

How might the changes that you identified affect the protein’s structure?

In scenario 1 and 2, the modifications would have zero effect.

In scenario 3, the polar groups are detected on the surface of the protein, thus, it is correct to state that both glutamine and lysine are polar and the modifications will have zero effect.

With regards to scenario 4, the change will have  no impact, given that both glutamic acid and aspartic acids are R groups that are negatively charged.

Assuming that the mutations are adaptive, how should the changes that you identified affect the stability of the protein at low and high temperatures?

These mutations are critical for protein's three-dimensional structure stability.

For example, due to the proteins from thermophilic creatures, they are able to live at high temperatures and survive at low temperatures.

This is because they frequently have a large network of salt bridges on their protein surface, which offers thermo-stability to these proteins and prevents denaturation owing to the high temperatures in the environment.

1) Accumulation of excretory wastes in human blood and its excretion by the
kidneys leads to ...

Answers

Organs in the excretory system rid the body of metabolic waste products and pollutants. This includes the elimination of urea from circulation and other bodily wastes in humans. While solid wastes are eliminated from the large intestine, urea elimination takes place in the kidneys.

How do the kidneys work?

The body transforms nutrients from meals into energy. Waste products are left in the blood and bowel after the body has utilized all the required nutrients from meals.The waste products are expelled with the aid of the urinary system and kidneys. They also maintain the proper balance of water and substances like potassium and salt. The body's hazardous waste products from food metabolism are filtered by the kidneys and removed. If these waste products accumulate in the body, it may lead to issues. The body's fluid and acid-base balance are both regulated by the kidneys.The kidneys are two bean-shaped organs. They are located below the ribs toward the middle of the back. Through microscopic filtering organs called nephrons, the kidneys eliminate waste substances from the blood called urea. Each kidney has roughly a million nephrons. A glomerulus, a ball of tiny blood capillaries, and a renal tubule, a tiny tube, make up each nephron. The glomerulus receives blood and filters it there. The water and other materials are added to or subtracted from the filtered fluid as it travels through the tubule. Urine is the liquid that is left over.After the urine is created, it flows through the kidney's nephrons and down its renal tubules. The renal pelvis receives urine from the calyces, which then directs it into the ureter. It then descends and enters the bladder from here.The kidneys perform a number of essential tasks, including filtering waste from the blood and assisting with the body's fluid and other material balance.
