The statement that is not true related to the protein structure is option b.  Proteins' tertiary structure is dictated by R group bonds.

It is classified as the  three dimensional shape of the protein.

In the tertiary structure it does contain the  single polypeptide chain that we called as the backbone or there more than one protein secondary structures

Also, it should not be dictated by R group bonds.

Therefore, we can conclude that the option b is correct.

If I am understanding correctly, the first thing they are asking you to do is match nitrogen bases.

Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C).

Then, whichever are the double strands, cut them out and put them into you notebook. (I am not sure where the notebook is, but I am assuming you know)

Then in the speech bubble next to the picture of Chargaff- talk about his rule.

What does the rule mean?

What does the rule explain?

How is the rule demonstrated?

Lastly, finding percents. What percent of the pairs has Adenine in them?

For example:

If I look at this pairing below

A →T

T→ A

G →C

C→ G

50% of the pairs include Adenine.

Answer:

If the sequence of nitrogenous bases of a DNA strand is ATCTAGGCCG, the complementary strand would be TAGATCCGGC, with a percentage of guanine 30%, cytosine 30%, adenine 20% and thymine 20%, according to Chargaff's rule.

Explanation:

DNA is made up of sequences of nitrogenous bases, which are adenine (A), guanine (G), thymine (T) and cytosine (C).  The bases of one strand are matched with the bases of another, according to the complementarity of nitrogenous bases, where:

The image shows a DNA chain whose chain is complementary:

DNA Strand given      Complementary Strand

    Adenine                                Thymine

    Thymine                                Adenine

    Cytosine                                Guanine

    Thymine                                Adenine

    Adenine                                Thymine

    Guanine                                 Cytosine

    Guanine                                 Cytosine

    Cytosine                                Guanine

    Cytosine                                Guanine

    Guanine                                 Cytosine

Therefore, in a DNA molecule there is as much adenine as thymine, and an equal amount of cytosine and guanine. In this example there are 4 molecules of adenine, 4 molecules of thymine, 6 guanines and 6 cytosines.

The proportion or percentages of nitrogenous bases can be calculated according to Chargaff's rule.

Chargaff was able to establish that in a DNA molecule the ratio of purine:pyrimidine of 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine, according to the complementarity of bases.

Taking into account the law of the base pair, if in a DNA chain there is 30% of Adenine, in the molecule there is:

Guanine 30%

Cytosine 30%

Adenine 20%

Thymine 20%

Total ..... 100%

Organisms that obtain their energy from producers or other consumers are heterotrophs.

An organism is referred to as a heterotroph if it consumes other plants or animals for food and energy. Its origins are in the Greek words hetero, which means "other," and trophe, which means "nutrition." Autotrophs and heterotrophs are two general classifications of organisms depending on how they receive energy and nutrients.

To confirm about the validity of a company's claim about the efficacy and safety of a new pesticide, a consumer can do: (b) additional studies that will be the reliability check for the claims.

Pesticides are the chemicals used to prevent the damage if crops against harmful small insects or other small organisms. These chemical agents can either kill the pests or slow their growth to a great extent. Pesticides can be of three types: insecticides, fungicides and herbicides.

Reliability check in case of pesticides can be defined as the tests and surveys performed to check for their effectiveness. It is in simple terms a quality check. Reliability check for pesticides are very important because if these pesticides are hazardous, they can cause chronic illness in humans after the consumption of such crops.

Explanation:

The organelle here is lysosome as it collects the trash of the cell. The correct option is B.

A lysosome is a cell organelle that contains digestive enzymes and is membrane-bound.

Lysosomes are involved in a variety of cellular processes. They degrade extraneous or worn-out cell parts. They could be used to eliminate invading viruses and bacteria.

Lysosomes serve as the cell's digestive system, degrading material taken in from outside the cell as well as digesting obsolete components of the cell itself.

The lysosome's interior is acidic and contains numerous enzymes that break down molecules.

It is known as the cell's recycling center, but this does not imply that it only plays a passive role in the cell.

Thus, the correct option is B.

Your question seems incomplete, the missing options are:

The correct answer is Ribosomes is the single molecule that could do both cellular work and replicate itself.

Ribosomes have two primary functions: message decoding and peptide bond formation. The ribosomal subunits are made up of two large ribonucleoprotein particles (RNPs) of unequal size. Each subunit is composed of one or more ribosomal RNAs (rRNAs) and a large number of ribosomal proteins (r-proteins). The ribosome is an ancient molecular fossil that can be used to peer into the origins of life. In all living systems, the ribosome, which is composed of RNA and protein, converts mRNA to coded protein. Translation is infused with universality, economy, centrality, and antiquity. Because the ribosome is so important to all aspects of life and reproduction in an organism, rapid change is unlikely to survive. The ribosome components are an excellent resource for studying the evolution of all organisms because all cellular organism have ribosomes .

Based on a number of considerations, it is hypothesized that at some time in the evolution of life, there must have been a single molecule that could do both cellular work and replicate itself. A possible molecule that has been suggested is a catalytic RNA molecule, now called a ?

Organism represents an individual form of life such as an animal, plant, or single-celled life form. A prokaryote or a eukaryote can be a unicellular organism.  Eukaryotic organisms have a membrane-bound cell nucleus as well as extra membrane-bound compartments known as organelles (such as mitochondria in animals and plants and plastids in plants and algae, all generally considered to be derived from endosymbiotic bacteria)

Fungi, mammals, and plants are examples of eukaryotic organism kingdoms.

Monosaccharide profiling of glycoproteins by capillary electrophoresis with contactless conductivity detection is saccharides.

Saccharides form one of the major constituents of the biological macromolecules in living organisms. Many biological processes including the protein folding, stability, immune response and receptor activation are regulated by glycosylation.

In this work, we optimized a capillary electrophoresis method with the capacitively coupled contactless conductivity detection for separation of eight monosaccharides commonly found in glycoproteins, namely D-glucose, D-galactose, D-mannose, N-acetyl-D-glucosamine, N-acetyl-D-galactosamine, D-fucose, N-acetylneuraminic acid, and D-xylose. A highly alkaline solution of 50 mM sodium hydroxide, 22.5 mM disodium phosphate, and 0.2 mM CTAB (pH 12.4) was used as background electrolyte in a 10 µm id capillary. To achieve baseline separation of all the analytes, a counter-directional pressure of –270 kPa was applied during the separation. The limits of the detection of our method were below 7 µg/ml (i.e., 1.5 pg or 1 mg/g protein) and the limits of quantification were below 22 µg/ml (i.e., 5 pg or 3 mg/g protein). As a proof of the concept of our methodology, we performed an analysis of monosaccharides released from fetuin glycoprotein by acid hydrolysis. The results show that, when combined with an appropriate pre-concentration technique, developed method can be used as a monosaccharide profiling tool in glyco-proteomics and complement the routinely used LC-MS/MS analysis.
