C. The introduction of a new gene that can bind with the abnormal gene to inhibit its action.

Explanation:

Gene therapy is a new system of treatment being introduced that employs the use of genes as against drugs in the treatment of diseases. Most diseases arise as a result of a mutation in a gene. Gene therapy seeks to replace these mutated genes with healthy genes. The bad gene could also be inactivated or knocked out to prevent further damage.

So, when a new gene is introduced and made to bind with an abnormal gene to inhibit its action, that is a knockout process employed in gene therapy. The practice is still under trial.

Autocatalytic replication is an important part of the prebiotic evolution leading to the origin of life on Earth. It is believed that this replication process occurred spontaneously in a prebiotic environment, leading to the formation of the first living organisms.

The Autocatalytic replication was facilitated by the presence of organic molecules, like RNA and amino acids. Over time, these organisms evolved and adapted to their environment, eventually giving rise to the complex life forms we see today.

Synapsids were the first reptiles to develop a single temporal opening in their skulls, which allowed for a larger jaw muscle and improved biting ability. Synapsids and cynodonts are two groups of reptiles that played a key role in the evolution of mammals, including humans. The adaptation allowed them to compete more effectively for resources and led to their dominance during the Permian period.

Cynodonts were a group of advanced synapsids that evolved during the Triassic period they had a number of adaptations that made them well-suited to life on land, including more efficient lungs, better hearing, and the ability to regulate their body temperature. These adaptations allowed them to thrive in a variety of environments and gave rise to the first true mammals.

Yes, all human cells are capable of mitosis and cell division.

Mitosis is a process by which a single parent cell divides to make two new daughter cells. Each daughter cell receives a complete set of chromosomes from the parent cell. This process allows the body to grow and replace cells.

Any kind of internal or external damage leads a signal ti cell to divide at a faster rate so that the healing occurs.

Through the process of mitosis, an equal number of cells are produced. Repair of cells occurs only in somatic cells and mitosis tends to divide somatic cells

For example When cells are lost or when a tissue fragment breaks. Therefore, mitosis will produce a huge number of new cells over time to plug the hole and enlarge the tissue once more. This guarantees that the tissue is restored to normal function. Similar to how a wound heals You will notice that the blood gap closes within a few days and that new platelets and skin cells are developing to plug the hole and make additional skin. The forming of new cells of the skin is due to a continuous type of division which is mitosis

The population of beetles in the next three generations, considering the carrying capacity, is y1 = 130 beetles, y2 = 130 beetles, and y3 = 130 beetles.

The population of beetles can be calculated using the formula: y = y0 * (1 + r)^n, where y is the population at a given generation, y0 is the initial population, r is the intrinsic growth rate (expressed as a decimal), and n is the number of generations.

Given that the initial population (y0) is 60 beetles and the intrinsic growth rate (r) is 150% (or 1.5), we can calculate the population for the next three generations.

For the first generation (y1), we substitute y0 = 60, r = 1.5, and n = 1 into the formula: y1 = 60 * (1 + 1.5)^1 = 60 * 2.5 = 150 beetles.

For the second generation (y2), we substitute y0 = 60, r = 1.5, and n = 2 into the formula: y2 = 60 * (1 + 1.5)^2 = 60 * 6.25 = 375 beetles.

For the third generation (y3), we substitute y0 = 60, r = 1.5, and n = 3 into the formula: y3 = 60 * (1 + 1.5)^3 = 60 * 15.625 = 937.5 beetles.

However, since the environment can only sustain a maximum population of 130 beetles, we need to consider the carrying capacity.

To find the population at each generation while considering the carrying capacity, we compare the calculated population with the carrying capacity and use the smaller value as the population.

For y1, the population is 150 beetles, which exceeds the carrying capacity of 130 beetles. Therefore, y1 = 130 beetles.

For y2, the calculated population is 375 beetles, which is also above the carrying capacity. Thus, y2 = 130 beetles.

For y3, the calculated population is 937.5 beetles, which is still above the carrying capacity. Therefore, y3 = 130 beetles.

Cytokinesis. Following chromosomal segregation, a single cell contents really split into two cells. When a ring of fibres on the inside surface of the membrane contracts, it causes the cell membrane to pinch in at first.

The main component of these fibres in this scenario shares structural similarities with eukaryotic tubulin (which makes up microtubules), but performs a comparable role to actin in an animal cell's contractile ring. The two cells are eventually separated as the membrane closes in and deposits new cell wall components. The final stage of cell division, known as cytokinesis, is when the two daughter cells physically separate from one another.

Answer:

Answer:

a. AAA TCG

b. CGA AAT

Explanation:

DNA and RNA both have 4 nitrogenous bases, and the base pairing rule dictates which one each will bond with. If you have a hard time visualising the base paring rule, imagine it as two pairs of lovebirds.

So in DNA:

A ♡ T

(likewise) T ♡ A

C ♡ G

(likewise) G ♡ C

A will only bond with T, and C will only bond with G. Likewise, T will only bond with A and G with C. But you might've noticed that in your picture, there are no T! This is because this is a RNA strand instead of a DNA one, so the base paring rule is a bit different.

In RNA:

A ♡ U

(likewise) U ♡ A

C ♡ G

(likewise) G ♡ C

When transcribing RNA strands into DNA ones, the U's always translate to A, and the A's always translate to T's! You can think of the U's as the T's of RNA -- just (mentally) replace all the U's in the picture with T's, and the DNA base pairing rule applies. T's always translate to A, and the A's always translate to T's, right?

Another way you can make solving this question easier is to rearrange the bases vertically so it looks much more like the familiar base pairing rules layout!

U ♡ A

U ♡ A

U ♡ A

A ♡ T (because we're going RNA -> DNA, and DNA doesn't have base U!)

G ♡ C

C ♡ G

UUU AGC -> AAA TCG

In the answer you will see that all 4 DNA bases (A,T,C,G) are present :)

tdlr; if you're going RNA -> DNA, no U's in answer (replace them with T's!). If you're going DNA -> RNA, no T's in answer (replace them with U's!)

In either way both of them love A very much and will always translate into A :)

Some diseases caused by smoking:

Explanation:

Heart Disease: A person's arteries might get blocked as a result of smoking. This prevents proper blood flow, which might result in a heart attack or stroke.

Emphysema (a lung disease): The lungs' alveoli are damaged by the chemicals in tobacco smoke. Their walls weaken, and when you breathe in, they don't properly inflate. Coughing may cause them to explode. As a result, less oxygen is transported through the bloodstream, which causes shortness of breath.

Respiratory Infections: Mucus is produced by the cells in your trachea, which serves as a filter for dust and bacteria. Moreover, your airways are kept clear by cilia, which push mucus into your stomach. The cilia are prevented from moving by chemicals in tobacco smoke. This allows for mucus to enter your lungs, which makes breathing difficult and frequently results in infections. Smokers cough this mucus up, which can harm the lungs further.

Cancers: At least 70 of the over 5000 chemicals released by cigarette smoke can cause cancer. In our lungs, the dangerous chemicals spread throughout our entire body. DNA is harmed by cigarette chemicals. Cells have a tougher time repairing any DNA damage due to the chemicals in cigarettes. Moreover, they harm the DNA that guard against cancer. Cancer is brought on by the build-up of genetic damage in a cell over time.
