which part of a dna molecule is responsible for the direct coding

In a population, alleles at a microsatellite locus differ from each other in terms of the number of repeating units (also known as repeats) of a specific DNA sequence.

Microsatellites are short, tandemly repeated sequences of DNA that are present in multiple copies within the genome. The number of repeats can vary greatly among individuals and even within a single genome.

In a population, the different alleles at a microsatellite locus will differ from each other in the number of repeating units. For example, one allele may have 10 repeating units, while another allele may have 15 repeating units. These differences in the number of repeats result in differences in the length of the microsatellite DNA sequence.

The variation in the number of repeats at microsatellite loci is a result of mutations that occur during DNA replication. These mutations can lead to the addition or deletion of repeating units, resulting in changes in the length of the microsatellite sequence.

Microsatellite variation can be used to study population genetics, ancestry, and the evolution of populations. Because of the high levels of variability and rapid mutation rates, microsatellite loci can be used to track the movement of populations over time and to identify related individuals.

In conclusion, alleles at a microsatellite locus in a population differ from each other in terms of the number of repeating units of a specific DNA sequence. These differences result from mutations that occur during DNA replication.

The statement that is true about chromatin is that it is composed of loose strands of DNA.

The DNA of eukaryotic cells is arranged differently from that of prokaryotic cells, and the genomes of most eukaryotes are far more complicated than those of prokaryotes. Prokaryotes have only one chromosome, which is typically a circular DNA molecule and contains their whole genome. The genomes of eukaryotes, in contrast, are made up of several chromosomes, each of which contains a linear DNA molecule. All eukaryotes share the same fundamental chromosomal structure, despite the fact that the numbers and sizes of chromosomes vary greatly between different species. Chromatin, the name given to the protein-DNA complexes found in eukaryotic cells, normally has a protein content that is roughly twice that of DNA. The main chromatin proteins are the histones, which are tiny proteins with a high concentration of basic amino acids that make it easier for them to connect to the negatively charged DNA molecule.

If a severe drop in blood pressure is not restored, this will most likely lead to kidney failure.

When blood pressure drops, the kidneys are not receiving enough blood and oxygen to function properly. This can cause reversible injury to the kidney tubules, leading to a temporary decline in kidney function. However, if blood pressure is not restored, the injury to the kidney tubules can become irreversible and lead to more widespread damage in the kidneys.

If the kidney damage progresses, it can result in complete kidney failure, also known as end-stage renal disease. This is a serious condition that requires treatment, such as dialysis or kidney transplant, to maintain life. In some cases, kidney failure can be fatal if left untreated.

Too much transpiration cause a plant to have too little water.

Plants lose water vapour through their stomata through a process called transpiration. When the weather is extremely hot, the plant loses water vapour, which cools it down. Water from the stem and roots flows upward or is "drawn" into the leaves. Abscisic acid, a plant hormone that induces the stomatal pores to close and lessens water loss during the release of oxygen and intake of carbon dioxide, is released by dehydrated mesophyll cells when there is less water available for the plants.

When plants lose too much water, their rate of absorption rises and they begin to wilt. The cells of the plants wilt when this happens, losing water and becoming dry. Water evaporation happens quickly in the summer when the weather is dry and hot. Plants must be able to keep from losing too much water in order to survive. Plants have some adaptations, including features like the cuticle and leaf hair that reduce excessive water loss.

In areas of Africa in which malaria is prevalent, many human populations exist in which the allele that produces sickle-cell disease and the allele for normal red blood cells occur at constant frequencies, despite the fact that sickle-cell anemia disease frequently causes death at an early age. This is an example of balancing stabilizing selection.

Balancing stabilizing selection a type of natural selection in which two or more alleles of a gene are maintained in a population at constant frequencies over time. In this case, the presence of the sickle-cell allele provides a benefit in the form of resistance to malaria, a serious and often deadly disease that is prevalent in many parts of Africa.

People who have the sickle-cell allele are less likely to get sick with malaria because the sickle-cell shape of the red blood cells makes it harder for the parasites to infect them.

On the other hand, people who have two copies of the sickle-cell allele will develop sickle-cell anemia, a serious condition in which the red blood cells take on a sickle shape.

The balance between sickle-cell allele and the normal red blood cell allele are maintained in the population at constant frequencies. This is why the sickle-cell allele and the normal red blood cell allele both occur at high frequencies in populations where malaria is prevalent.

The sickle-cell allele provides a survival advantage against malaria, but having two copies of the allele is lethal. This creates a balance in which the sickle-cell allele and the normal red blood cell allele both persist in the population.

When an allele is the only variant of a gene in a population, it is said to be fixed. An allele is a specific version of a gene that occurs at a specific locus (position) on a chromosome. If a population has only one allele for a particular gene, it is said to be fixed for that allele, meaning that all individuals in the population have the same version of the gene.

Fixation of an allele in a population can occur through genetic drift, a random process that can result in the loss of one or more alleles over time, or through natural selection, where one allele confers a survival advantage over others and becomes more common in the population over generations. Having a fixed population means that there is limited genetic variation, which can be both beneficial and harmful. On one hand, it can lead to a more uniform and predictable population, but on the other hand, it can leave the population vulnerable to diseases and environmental changes. Therefore, it is important to maintain genetic diversity within populations to ensure the long-term health and survival of a species.
