what are the the four main categories of organic macromolecules ?

Answers

Answer:

There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions.

Four main categories of organic macromolecules are as follow:

carbohydratelipidsproteinsnucleic acidWhat are macromolecules?

Macromolecules are polymers containing long chains of molecular sub-units known as monomers. These play an important role in biophysical processes and composed of thousands of atoms that are covalently bonded.

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.

Nucleic acids are biopolymer macromolecules and composed of nucleotide. The function is to carry genetic information which helps to make RNA.

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

Answers

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.

The correct answer is B. All organisms go through both mitosis and meiosis.

Explanation:

The same mechanisms of chromosomal segregation are at work in both mitosis and meiosis -- centrosomes, microtubules and motor proteins. Both mitosis and meiosis are multistage processes. The stages are interphase, prophase, metaphase, anaphase and telophase. The same general processes occur in each of these stages for mitosis and meiosis.

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.

Introspection is one of the many sleeping disorders experienced
by people with sleep apnea.
Select one:
True
False​

Answers

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.

It’s a guess but it’s not C. Because that would be high albedo. Low albedo would probably be D. An Iceberg

Explanation: Albedo is the measure of the reflectivity of a material. A high albedo means it reflects a lot of light and a low albedo means it absorbs a lot of light.

My Second Explanation: The higher the albedo, the more the surface reflects light. Snow and ice have high albedos; a dark rock would have a lower albedo.

Answers

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).
