Answer:
The aspect of translation that makes it so challenging for the cell is that it involves too many steps and too many molecules and organelles. mRNA associated with rRNA and tRNA. rRNA reading mRNA in a specific direction. Codon sequences indicating where to start and where to finish the synthesis. Different codons codifying for different aminoacids and tRNA recognizing those codons to add the correct amino acid to the chain. If the protein is destined to exportation, RER and Golgi complex are also involved in the process.
Explanation:
In protein synthesis, the first step is to synthesize messenger RNA, mRNA. The transcription is the coping process of the DNA section, and it happens in the nucleus. After that, the translation occurs when the formed mRNA moves to the cytoplasm through the nucleus membrane pores.
Once in the cytoplasm, it begins the translation process. mRNA meets a free ribosome, which is the primary structure for protein synthesis. Ribosomes are composed of two subunits, a big one and a small one. They also associate with different tRNA that carrying amino acids. Ribosomes might be floating freely in the cytoplasm or can be attached to the rough endoplasmic reticulum.
The ribosome reads mRNA in the 5´ to 3´ direction, and, according to the codons that are being readen, tRNA transfers the correct amino acids to build the polypeptide chain. Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid through the action of the aminoacyl-tRNA synthase enzyme. The whole complex, amino acid + enzyme + tRNA is named aminoacyl-tRNA. Considering that there are twenty amino acids available, there are also twenty complexes of aminoacyl-tRNA, one for each amino acid. tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.
Once the new amino acid links to the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.
The protein is synthesized from the amino terminus to the carboxy terminus, while the added amino acids to the chain are coded by a codon formed by three bases in the mRNA. mARNs also have a start and end codon that are the signals of the synthesis initiation and finish. When the ribosome reaches the end codon, protein synthesis is over.
And if the protein is destined for exportation or cell membrane, its synthesis also involved organelles like the Rough endoplasmic reticulum and the Golgi complex.

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.
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.

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.

In the DNA double helix, archaic pairs with thymine and cytosine pairs with
guanine.
True or false?
Answer:
False
Explanation:
'Adenine' pairs with thymine and cytosine pairs with guanine in a DNA double helix.
It is false that in the DNA double helix, archaic pairs with thymine and cytosine pairs with guanine.
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.
Thus, the given statement is false.

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.Learn more at: https://brainly.com/question/12327654?referrer=searchResults

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
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.

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.
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.
