Comparing amino acid sequences in proteins has been used to determine the relatedness of organisms. Below is a graphic that show

Tju [1.3M]

Answer:

A) Species A and E are more closely related than either species are related to species D.

B) Between A and B = 99.1%

Between species A and C =97.5%

Between species B and C = 97.3%

Similarity in amino acids sequence reflects similarity in DNA sequence

C) Species A and E are most closely related

D) Species A and E have the most similarity in amino acid sequence, and hence DNA sequence.

Explanation:

A) The amino acid sequences of the protein, keratin, in species A and D has a difference of about 19 whereas species A and E have a difference of only 1. Therefore, it means that keratin in species A and D will have differences in structure whereas between species A and E, they would have almost the same structure.

Also, species D and E have a difference of 20 in their amino acids sequence, therefore, the structure of keratin in both species will have differences in structure.

B) Similarity between A and B:

450 - 4 = 446

In percentage: 446/450 × 100% = 99.1%

Similarity between A and C:

450 - 11 = 439

In percentage: 439/450 × 100% = 97.5%

Similarity between B and C:

450 -12 = 438

In percentage: 438/450 × 100% = 97.3%

The sequence of DNA of species determines their amino acid sequences because information in DNA is transcribed to RNA which are then used to make proteins. Therefore, if a species are very closely related, they are expected to have very similar genetic sequences and thus proteins too. This is reflected in similarity between amino acid sequences in their proteins.

C). Species A and E are most closely related.

D) Species A and E have only a single difference in their amino acids sequence for Keratin. This translates to about 99.7% similarity which is the highest among all the species compared. Therefore, species A and E are most closely related.

Imagine that your lab is synthesizing a new type of cell. One of your colleagues suggests that your synthetic cell should use pr

Gnom [1K]

Answer:

In a scenario in which I have to synthesize a cell and decide why I have to pick one from Prokaryotic or eukaryotic because of their differences in the speed of the process. The characteristics that make it faster in prokaryotic cells are:

The primary transcript in prokaryotes does not undero further processing, so transation can begin immediatly.

Multiple proteins can be synthetized from a single polycistronic MRNA molecule.

Prokaryotes lack a nuclear envelope, so translation can begin on mRNA even before transcription of the mRNA is complete.

Explanation:

The nature of Prokaryotes makes them undergo the synthesizing process quicker than Eukaryotes because they don't require a preliminary process to start it as Eukaryotes have to undergo one. This is because their composition, Eukaryotes are cells without many organelles like mitochondria or even nucleus. this is also the reason for eukaryotes to be slower in the process of synthesizing mRNA because they don't have organelles to process it faster. Finally, because they don't have a nucleus to help them assimilate the mRNA.

Which of the following are characteristics of archaeal cell membranes that probably help them survive at very high temperatures?

torisob [31]

Answer:

Option-B, C and E

Explanation:

Archaebacteria are a group of prokaryotes which can survive the extreme conditions. The archaebacteria which can survive very high temperature are called hyperthermophiles. The hyperthermophilic bacteria can survive temperature range between 70 t 125 °C observed in hydrothermal vents.

The archaea bacteria can withstand the high temperature as their membrane is adaptive. The membrane of the archaea is more stable due to the ether linkage which makes carbon less chemically reactive. The phospholipids possess a monolayer which decreases the layer fluidity and thus the unwanted movement of molecules.

The archaea also contain cyclopentane rings in the ester-linked phospholipids which allows tight pacing of the molecules which decrease the movement of solute into and out of the cell.

Thus, the selected options are correct.
