Genetic polymorphism is the existence of multiple alleles of a single gene.
What are genes?Genes are regions of DNA which code for a particular protein or any other gene product.
Genes can exists as a single copy or as multiple copies.
Alleles are alternate forms of a particular gene.
A single gene that has two or more alleles present in a population is known as genetic polymorphism.
Therefore, multiple alleles of a single gene is known as genetic polymorphism.

In a separate study, 68 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Sonora, Mexico. The other three were in Chihuahua, Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three Chihuahua locations were slightly darker than the dark-colored mice from the Sonora population. The entire Mc1r gene was sequenced in all 68 of the mice collected. The mutations responsible for the dark fur color in the Sonora mice were absent from the three different populations of Chihuahua mice. No Mc1r mutations were associated with dark fur color in the Chihuahua populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases.

How does this study support the concept that natural selection is not random?
Answer:
The study supports the concept that natural selection is not random because in different areas with the same or very similar environmental characteristics, the same phenotype was produced by different types of mutations.
Explanation:
All of the sampled animals are inhabiting dark substrate. Probably animals needed to camouflage to survive. Natural selection must have driven them to produce dark color, similar to the substrate color. So animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. The environmental condition is favoring the same phenotype.

Che healthy way to lose weight is to...
Drink a lot of water
O Take in slightly less calories than you use daily
O Eat no fats
O Eat no carbohydrates
1 point
Answer:
O Take in slightly less calories than you use daily
Explanation:
It has been shown that the healthiest diets to lose weight are those where individuals consume fewer calories than normal and simultaneously by taking care of consuming all essential nutrients in adequate quantities.
The essential nutrients to be consumed in a healthy diet include:
1- macronutrients, especially proteins (amino acids) to avoid muscle loss as well as normal metabolic functions, and fats, which are required to absorb some micronutrients (i.e., liposoluble vitamins)
2- micronutrients, which include vitamins (e.g., vitamin D, vitamin C, etc) and minerals (e.g., iron, calcium, etc).
name two characteristics that all these animal share ( frog, buck, doves, lizard, dragonflies )
Answer:
They all have a beating heart, and a brain
Explanation:
Beating the heart and a brain is the two characteristics that all these animal shares frog, buck, doves, lizard, and dragonflies.
What are the different characteristics of animals?Frogs are cold-blooded animals and are classified into the class of amphibians, they are vertebrate animals with backbones.
The lizard was included in the class reptilia, they are creeping and burrowing terrestrial animals situated on the land, and also have scales on their body. Similar to the frog, they are also cold-blooded animals having a backbone.
The major classification of the animals is done by the presence of a backbone, which differentiates them in vertebrates and invertebrates.
Therefore, in the given question all the animals share common feature of having a heart and brain.

Introspection is one of the many sleeping disorders experienced
by people with sleep apnea.
Select one:
True
False
Answer:
The statement is false.
Explanation:
Sleep apnea is a respiratory disease characterized by the fact that people who suffer from it habitually snore, have repeated stops of breathing (apneas) and drowsiness during the day. As a consequence, patients who suffer from it cannot rest well during the hours of sleep.The obstruction of breathing causes a decrease in oxygen levels in the body, the persistence of this lack of oxygen could cause pulmonary hypertension and a future right-sided heart failure or myocarditis. Introspection, on the other hand, is the immediate reflective capacity of the human mind to know its own states; it is not associated with sleep apnea.

The ADG1(ADP glucose pyrophosphorylase 1) is involved in flowering timing in plants. You are interested in developing a DNA probe using partial protein sequence information. Part of the amino acid sequence is Glu-Glu-His-Asp-Val-Leu 1. determine the possible antisense oligo nucleotides possible from this amino acid sequence 2. How many total unique different oligonucleotide would need to be produced to cover all possibilities
Answer:
1) UUC-AUG-AUC-AAG-UAA.
2) 48
Explanation:
1) Determine the possible antisense oligo nucleotides possible from this amino acid sequence
Given that the peptide sequence is = Glu-Glu-His-Asp-Val-Leu 1.
we will use a codon table to show the codons and Anticodons for each of the Amino acids
Amino Acid Codons Anticodons
Glu GAA, GAG UUC, CUC
His CAU, CAC AUG, GUG
Asp GAU, GAC AUC, GUC
Val GUU, GUC, GUA, GUG AAG, GAC, UAC,CAC
Leu UUA, UUG, CUU, CUC, CUA, CUG | UAA, CAA, AAG, GAG,UAG,CAG
From the table above
The possible antisense oligo nucleotide sequence is : UUC-AUG-AUC-AAG-UAA.
2) How many total unique different oligonucleotide would need to be produced to cover all possibilities
A desired peptide sequence requires 16 anticodons
Hence the total unique different oligonucleotide needed to be produced to cover all possibilities = 16 *3 = 48
The ADG1(ADP glucose pyrophosphorylase is involved in flowering timing in plants and a DNA probe is made by using partial protein sequence information. Part of the amino acid sequence is Glu-Glu-His-Asp-Val-Leu.
1. To determine the possible antisense oligonucleotides possible from this amino acid sequence:
Since, for every amino acid, there is a specific codon and anticodons are present so according to the given information, the possible antisense oligonucleotides for Glu-Glu-His-Asp-Val-Leu is UUC-AUG-AUC-AAG-UAA.
2) The total number of unique different oligonucleotides that would need to be produced to cover all possibilities is 48
since the amino acid sequence is Glu-Glu-His-Asp-Val-Leu has 16 anticodons and each anticodon have 3 nucleotides so the possible number of oligonucleotides are :
16×3 = 48.
What are codon and anticodon?A codon is a trinucleotide sequence of RNA that corresponds to a specific amino acid.
An anticodon is a trinucleotide sequence complementary to that of a corresponding codon in a messenger RNA sequence.
Thus, according to codon and anticodon, the possible antisense oligonucleotides for Glu-Glu-His-Asp-Val-Leu is UUC-AUG-AUC-AAG-UAA and a number of unique different oligonucleotides that would need to be produced to cover all possibilities is 48.

Carbohydrate is a biomolecule having carbon, hydrogen and oxygen atom.It is the main source of energy of the body.
Lipids are macromolecules that are insoluble in water and the main function is to serve as structural component of cell membrane.
Proteins are macromolecules that are extremely complex in structure and made up of amino acid residues joined by peptide bonds.
