Why do these sisters have different traits? Use these words in your response (protein, molecule, structure, trait, variation) describing what would determine these traits at the molecular scale.

Answers

Answer:

[Protein, Molecule, Structure, Trait, Variation]

Each offspring receives two copies or variations of each gene, one from their mother and one from their father. Each offspring can inherit a different combination of gene versions, so siblings can have different traits from each other and from their parents. The girl on the right has straight hair, whereas the girl on her left, has curlier hair. A gene code for a specific protein that's involved in a traits expression. In the structure of a cell, the proteins do much of the chemical work inside the cell, so they largely determine the traits and whose they are. Another thing to remember is genes are also made up of molecules. Thin strands twisted around each other like a spiral staircase.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Try to use the information I provided above...

GL.

The differences that occur at the molecular level or in the genes, will result in changes in the proteins which the genes code for bringing about variation in traits.

What is variation?

Variation refers to the changes that occur between individuals of the same species due to environmental or genetic factors.

The basis for variation is differences that occur at the molecular level.

The genes are regions of the DNA which code for a particular trait.

The DNA is composed of chains of polynucleotide molecules.

When differences occur at the molecular level or in the genes, the proteins which the genes code for will have differences in structure.

Thus, the individuals will show variation as in the case of the two sisters who show variation in height and hair structure.

Using established recombinant DNA technology, you insert a gene from a human immune cell into a bacterium. The bacterium expresses the protein corresponding to the inserted DNA. To your disappointment, you discover that the protein produced is useless and is found to contain many more amino acids than does the protein made by eukaryotic cells. Assuming that there is no mutation in the human gene, what is a reasonable explanation for why this happened

Answers

The group of choices associated with the question is -

The inserted gene does not have a start codon.

The inserted gene does not have a stop codon.

The inserted gene is not present in bacteria.

The inserted gene contained introns.

None of the above.

Answer:

The correct answer is - The inserted gene contained introns.

Explanation:

In the given case says that one gene inserted from human to bacteria that produces a protein with more amino acids than humans. In eukaryotic organisms, there is a process that removes the unwanted mRNA part during transcription and joins exons together, called splicing to form functional mRNA.

In this case. splicing does not take place as bacteria is a prokaryotic organism and splicing is exclusive to eukaryotic organisms like humans.

So introns are also translated into protein in bacteria due to lack of splicing genes.

Increasing the alveolar ventilation rate will Group of answer choices increase the partial pressure of oxygen in the alveoli. decrease the rate of oxygen diffusion from the alveoli to the blood. increase the partial pressure of carbon dioxide in the alveoli. decrease the rate of carbon dioxide diffusion from the blood to the alveoli. have no effect on either the partial pressure or diffusion rate of gases.

Answers

Answer:

Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.

Explanation:

Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.

A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli.  This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.

Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)

If the  alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.

If the  alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.

At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concluded that the Chondrichthyes diverged after the evolution of bone had started. What does this change demonstrate about the evolution of fishes

Answers

Answer:

The correct answer would be - Characteristics can be lost in evolution.

Explanation:

The new evidence helps in developing a new hypothesis. In this case, new evidence proved that the Chondrichthyes diverged after the evolution of bone had started instead of before the evolution started. This process called atavism where an ancestral genetic trait reappears after having lost. This leads to loss of the traits in the evolution

This can take place by knocking the mutation out to overriding the gene by the old gene or overriding the new trait by the old trait during the evolution period.

At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concluded that the Chondrichthyes diverged after the evolution of bone had started might be their characteristics lost in evolution according to atavism.

What is atavism?

Recurrence in an organism of a trait or character typical of an ancestral form and usually due to genetic recombination. This leads to the loss of the traits in the evolution.

Hence, Chondrichthyes diverged after the evolution of bone had started might be their characteristics lost in evolution according to atavism.

A genotype is a scoring of the form of variation gift at a given vicinity (i.e., a locus) in the genome. it can be represented by way of symbols. as an instance, BB, Bb, and bb may be used to represent a given variant in a gene.

A person's genotype is the mixture of alleles that they own for a selected gene. A person's phenotype is the combination of observable traits or trends. while an organism's genotype is at once inherited from its parents, the phenotype is merely influenced by way of genotype.

TOOK TEST

The difference between phase I and phase II of meiosis is: Phase I results in two diploid daughter cells and phase II results in four haploid daughter cells.

MEIOSIS:

Meiosis is a kind of division that results in the formation of four haploid daughter cells that are genetically different from one another.

Meiosis occurs in a two step division process namely: meiosis I and meiosis II.

Meiosis I involves division of homologous chromosomes and produces two daughter cells that are diploid (2n) while meiosis II involves the division of the sister chromatids and produces haploid (n) chromosomes.

Therefore, the difference between phase I and phase II of meiosis is: Phase I results in two diploid daughter cells and phase II results in four haploid daughter cells.

What is DNA double helix?

In molecular biology, the structure created by double-stranded molecules of nucleic acids like DNA is referred to as a "double helix."

A nucleic acid complex's double helical structure develops as a result of its secondary structure and plays a crucial role in establishing its tertiary structure.

One of the four bases—adenine (A), cytosine (C), guanine (G), or thymine—is joined to each sugar (T).

Adenine forms chemical bonds with thymine while cytosine forms chemical bonds with guanine to join the two strands together.

A broad head, prominent supraorbital ridges (brow ridges), and the absence of a prominent chin are characteristics of archaics that set them apart from anatomically modern humans.
