The average molecular weight of proteins encoded in the human genome is about 50,000. A few proteins are very much larger than this average. For example, the protein called titin, which is made by muscle cells, has a molecular weight of 3,000,000. Estimate how long it will take a muscle cell to translate an mRNA coding for an average protein and one coding for titin. The average molecular mass of amino acids is about 110 daltons. Assume that the translation rate is two amino acids per second.

Kane how is co-evolution of symbiotic prokaryotes with eukaryotes similar and different to co-evolution in parasite-host systems?

Answers

How co-evolution of symbiotic prokaryotes with eukaryotes similar and different to co-evolution in parasite-host systems is that co existing has provided a sense of advantage with in the environment. One example of this are the parasites. There are different kinds of symbiotic relationships and this shows how similar and different co-evolution is. Hope this helps.

What are mechanisms of action of Triclosan and Povidone?

Answers

Answer:

Povidone: its action is produced by oxidation and inactivation of cellular components.

Triclosan:  is absorbed by intact skin which determines its persistence and its speed of action is intermediate.

Explanation:

Povidona:

- It presents the same mechanism of action and spectrum of iodine.

- It is a water-soluble compound that results from the combination of iodine and polyvinylpyrrolidone, which improves the solubility of iodine and allows its gradual release into tissues. This effect determines less skin irritation and greater product availability over time.

- The term "available iodine" refers to the amount of iodine available as a reservoir and that of free iodine to the percentage in solution in working condition, that is, a 10% povidone iodine solution, contains 1% of available iodine and the iodine concentration Free is 1 to 2 parts of a million that remains until the available iodine is depleted. This product advantage is lost when diluted in water, since in these circumstances it behaves as an aqueous solution of iodine.

- Its activity can be diminished by the presence of blood or other organic matter.

- The concentrations commonly used as a surgical scrubber are 7.5% and 8% and in the one used for cures it is 10%.

- In relation to tincture of iodine or lugol, it presents less dermal irritation. They should be used with caution in newborns and burned

- Its antiseptic action is classified between high level and intermediate level. They are lethal in minutes for bacteria, fungi, viruses, protozoa, amoeba cysts and spores. However, in front of dry spores it requires a longer exposure time (hours).

- Iodized antiseptics have the advantage of being cheap.

Triclosan:

- It is a relatively new phenolic derivative that acts causing damage to the cell wall of microorganisms. It is broad-spectrum bacterial, better for Gram + and there is little information about its activity in viruses.

- It is absorbed by intact skin which determines its persistence and its speed of action is intermediate.

- No allergenic or mutagenic effect has been demonstrated in short periods of use.

- Its activity is minimally affected by organic matter.

- The concentrations of usual use are between 0.3% and 2%.

- It is mainly indicated for clinical handwashing where it is used in 1% breads and in 0.5% liquid preparations.

Chloroplast is the site for photosynthesis in plants. Thus, option A is correct.

What are chloroplasts?

Chloroplasts are the cell organelles present in the plants. Chloroplasts are one such type of plastids.

Chloroplasts are green in colour. They contain a green coloured pigment called chlorophyll which traps the solar energy.

The solarenergy is converted into chemicalenergy by a process called photosynthesis. The organic molecules so produced are the energyrich compounds.

Chloroplasts are chiefly found in the mesophyll region of the leaves.

Chloroplast consists of grana and stroma regions. The grana contain disc shaped coin like structures called thylakoids. The matrix of chloroplasts constitutes stroma region.

Various enzymes, DNA, ribosomes etc are found within the chloroplasts. Hence, they are also referred as 'cellwithinthecell'.

Chloroplasts have unique feature of self-replication. Chloroplasts are similar in function to mitochondria in animal cells.

Therefore, chloroplasts are important plant structures for photosynthesis.

In plants, photosynthesis takes place in chloroplasts. Option A is correct.

What is Chloroplast ?

Plant, algae, and certain protist cells have membrane-bound organelles called chloroplasts.

So, They are in charge of the process known as photosynthesis, which turns light energy into chemical energy in the form of glucose in green plants and some other animals. Life on Earth is supported by this essential mechanism of energy conversion.

Therefore, In plants, photosynthesis takes place in chloroplasts.

a cell with 18 chromosomes divided by meiosis. which of the following statements best describes the expected daughter cells?

Answers

Final answer:

When a cell with 18 chromosomes divides by meiosis, the result would be four daughter cells, each with 9 chromosomes, option(c). This is because meiosis reduces the number of chromosomes in each daughter cell by half.

Explanation:

The best description of the expected daughtercells when a cell with 18 chromosomes divides by meiosis is: The result would be four daughter cells, each with 9 chromosomes. This is because meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell. The process of meiosis begins with a parent cell that is diploid, meaning it has two complete sets of chromosomes. During meiosis, this cell undergoes two rounds of division, resulting in four haploid daughter cells, with each containing half the number of chromosomes as the original parent cell. In this case, the original cell has 18 chromosomes, so each of the four daughter cells will end up with 9 chromosomes, option(c).
