specific macrophage populations promote both cardiac scar deposition and subsequent resolution in adult zebrafish

1 answer:

7 0

Specific macrophage populations help by promoting both cardiac scar deposition and subsequent resolution in adult zebrafish. It is a correct statement.

<h3>What is the effect of macrophages on zebrafish?</h3>

There is an inflammatory response to tissue injury. It is an important part of the process of repair. Scar tissue deposition is a direct downstream consequence of this kind of response in several tissues including the heart tissue.

Adult zebrafish do not only have the ability to regenerate lost cardiomyocytes. They can also remodel and resolve a scar which is extracellular, in tissues like the heart. This resolution of the scar is a poorly understood process.

Therefore, specific macrophage populations help by promoting both cardiac scar deposition and subsequent resolution in adult zebrafish.

1) 35mL to L 1 L = 1000ml so, 35mL = 35÷1000=0.035L

2) 950gm = 1Kg =1000g SO, 950÷1000= 0.950 Kg

3) 275mm to cm= 1mm= 1÷10 cm so, 275÷10= 27.5cm

4)1000mL to L = 1L=1000ml so, it will equal to 1L

5)4500mg to g = 1mg= 1÷1000g so, it will equal to 4.5g

6)25cm to mm = 1cm= 10mm so, 25X 10= 250mm

7)0.005Kg to mg, so 1Kg= 10∧6 mg so, 0.005X10∧6= 5000mg

8)0.075m to cm, so 1m =100cm so, 0.075X100= 0.75cm

9)15 g to mg , so 1g = 1000mg so, 15X1000= 15000mg

The nucleoside analogue acyclovir, which is used to treat herpes simplex virus (HSV) infections, lacks a 3′ hydroxyl group (–OH)

Dima020 [189]

Answer:

There won't be any functional viral DNA synthesis

Explanation:

First of all, you must consider that the HSV has a double-stranded, linear DNA genome. Furthermore, the DNA skeleton is made of the 5'-3' phosphodiester bond. In other words, the 5-phosphat of a nucleotide will bond the 3' OH of the Deoxyribose (see image).

Therefore, if you add a molecule which lacks the 3' OH, such as acyclovir, and has a similar chemical structure to a regular nucleotide, the DNA polimerase will be able to add acyclovir to the main backbone of the viral genome. All in all, you'd be ''cheating'' the DNA pol.

Hence, wherever acyclovir was integrated, there won't be any chance to form a 5'-3' phosphodiester bond. The protomolecule will not be stable and will soon be degradated.
