You will find the completed strand in the attached files

Answer and Explanation:

First, we need to recognize each strand, the original one and the complementary one. We can recognize the original strand because bases are already given. So,

Now we need to recognize and pair the bases. Names are written with their letters.

Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines. Adenine and guanine derive from purines, while Thymine and Citocine derive from Pyrimidines.  

In the DNA molecule, Adenine (Purine) forms pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. Two hydrogen bonds join the A-T pair, and three hydrogen bonds join the G-C.

Once we drag the base labels to their targets, we need to recognize each of the strain extremes.

One of the extremes has a phosphate group, which is named 5´. The other extreme has a hydroxyl OH named 3´. Both of them are readen in the 5´to 3´ direction. The polymerase enzyme reads the original strand in 5´ to 3´ mode, and the molecule lecture goes from 3´to 5´.

So, by looking at the labels, we will recognize the phosphate extreme and the hydroxyl one. We will place in the superior extreme of the original strain the phosphate group 5´ and in the other extreme the OH 3´. These positions will give us the direction reflected by the arrow. The complementary strand will have the same extreme labels but in opposite places. So first we will place the OH 3´ label in the superior extreme, and the phosphate 5´label in the inferior extreme, defining the direction reflected by the arrow.

"Cystic fibrosis (CF) is a genetic disorder caused by mutations in the CFTR gene. This gene provides instructions for the production of a protein that is responsible for the regulation of ion transport in cells."

Missplicing errors may result in CF for the following reasons:DNA mutations Mutations are changes that occur in the genetic material of an organism, DNA, which can affect how proteins are synthesized in the cell. Mutations in the CFTR gene can lead to the production of an abnormal protein or to the absence of the protein, which can cause CF.Protein synthesisMissplicing errors occur when the introns, non-coding regions, of a gene are not removed properly, leading to the production of an abnormal protein. In the case of CF, the missplicing of the CFTR gene can result in a protein that is not functional, leading to the symptoms of CF. Therefore, missplicing errors can cause CF by disrupting the normal protein synthesis process, resulting in an abnormal protein that does not function properly.

Cystic fibrosis (CF) is a genetic disorder caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The CFTR gene provides instructions for producing a protein that is responsible for maintaining the balance of salt and water in various organs, including the lungs, pancreas, and digestive system.

There are more than 1,700 different mutations identified in the CFTR gene that can cause cystic fibrosis. The most common mutation is known as ΔF508 (Delta F508), which accounts for approximately 70% of CF cases in individuals of European descent. This mutation involves a deletion of three nucleotides in the CFTR gene, resulting in the loss of a phenylalanine amino acid at position 508 of the CFTR protein.

The ΔF508 mutation leads to a defective CFTR protein that is misfolded and degraded before it reaches the cell surface. As a result, chloride ions are unable to move through the CFTR channel properly, disrupting the normal flow of salt and water across cell membranes. This disturbance affects the function of various organs, particularly the respiratory and digestive systems.

Other less common CFTR gene mutations can also cause cystic fibrosis, and the specific mutation a person carries can affect the severity and progression of the disease. Genetic testing is used to identify CFTR gene mutations in individuals suspected of having cystic fibrosis or as a part of carrier screening to assess the risk of passing on the condition to future children.

It's important to note that advances in genetic research and personalized medicine continue to expand our understanding of cystic fibrosis and the role of different mutations in the disease. New therapies and treatments are being developed to target specific genetic mutations and improve outcomes for individuals with cystic fibrosis.

Answer and Explanation:

Hello. I believe you want to know the result of a cross between a tall pea plant and a low pea plant. Well, to visualize the cross between these two plants, it is necessary to know which characteristics have the dominant and recessive alleles, as you did not mention, let's assume that the high plant has the dominant characteristic that will be represented by the "TT" alleles, while the low pea plant will have the recessive characteristic, represented by the "tt" allele.

A dominant characteristic is one that has dominant alleles in its composition. These alleles are represented by capital letters and signify the genes that determine a characteristic. The characteristic of a dominant allele will always be seen in the offspring of a cross, as long as that allele appears in hom0zygosis (two dominant alleles as "TT") or hetorozygosis (a dominant allele and a recessive allele as "Tt"). The characteristic of the recessive allele, on the other hand, will only be seen in the offspring of a cross, if it is presented in hom0zygosis (two recessive alleles as "tt").

In the figure that is attached below, you can see how a high pea plant (TT) crosses with a low pea plant (tt). This crossing is done by combining each allele of the tall plant with each allele of the plant, which resulted in a completely heterozygous offspring, with the "Tt" alleles. As mentioned above, the recessive characteristic only appears if there are two recessive alleles. In this case, we can consider that the entire offspring were tall pea plants, since all plants have the dominant allele.

True (T). Rapidly dividing cells have the ability to divide into two identical daughter cells more rapidly than normal cells.

This is because they are not subject to the same restrictions as normal cells when it comes to cellular division. Consequently, two known causes of rapidly dividing cells are mutations and stress. Mutations may lead to the formation of abnormal proteins or other cellular components that are unable to function correctly. Stress can also induce the overproduction of certain proteins or other cellular components.

Two known causes for rapidly dividing cells in cellular division are:

Cell Cycle Dysregulation: The cell cycle is a tightly regulated process that controls cell growth and division. Dysregulation of the cell cycle, such as the loss of cell cycle checkpoints or mutations in genes involved in cell cycle regulation, can lead to uncontrolled and rapid cell division. This dysregulation can result in the formation of tumors and is a hallmark of cancer.

Growth Factor Signaling: Growth factors are signaling molecules that stimulate cell growth and division. When cells are exposed to an excess of growth factors or when there is an abnormal activation of growth factor receptors, it can lead to uncontrolled cell division. Aberrant growth factor signaling pathways are implicated in various diseases, including cancer.
