5 0

Answer:

Topoisomerase is an enzyme which participates in the unwinding of DNA helix.

Explanation:

During transcription and DNA replication, the DNA needs to be unwound in order for the transcription/replication machinery to gain access to the DNA so it can be copied or replicate, respectively.

Calculate the final concentration of BSA in the problems below using the formula
Rudiy27

Answer:

A. C_2=1.5\frac{mg}{mL}

B. C_2=0.075\frac{mg}{mL}

C. C_2=0.01\frac{mg}{mL}

D. C_2=0.001\frac{mg}{mL}

Explanation:

Hello.

In this case, we must compute the final concentration in all the cases so we solve for it in the given equation:

C_2=\frac{C_1V_1}{V_2}

Thus, we proceed as follows:

A. Here, the final diluted solution includes the 300 μL of the 5 mg/ml-BSA and the 700 μL of TBS.

C_2=\frac{300\mu L*5\frac{mg}{mL} }{(300+700)\mu L}\\\\C_2=1.5\frac{mg}{mL}

B. Here, the final diluted solution includes the 50 μL of the 1.5 mg/ml-BSA, the 450 μL of water and the 500 μL of TBS.

C_2=\frac{50\mu L*1.5\frac{mg}{mL} }{(50+450+500)\mu L}\\\\C_2=0.075\frac{mg}{mL}

C. Here, the final diluted solution includes the 10 μL of the 1 mg/ml-BSA and the 990 μL of TBS.

C_2=\frac{10\mu L*1\frac{mg}{mL} }{(10+990)\mu L}\\\\C_2=0.01\frac{mg}{mL}

D. Here, the final diluted solution includes the 10 μL of the 0.1 mg/ml-BSA and the 990 μL of TBS.

C_2=\frac{10\mu L*0.1\frac{mg}{mL} }{(10+990)\mu L}\\\\C_2=0.001\frac{mg}{mL}

Best regards.

Compare and contrast the two cycles of matter
sertanlavr [38]

Answer:

The two cycles of the matter are the carbon and nitrogen cycle. Both of them are biogeochemical cycles, it means that the chemicals spend a portion of the cycle in living things and non-living things. They are also common in that they both recycle nutrients that are essential to all organisms. 

They are different in the manner that they cycle. Nitrogen is huge, 78% of the air around us is nitrogen. It cannot be used by plants or animals. Once the nitrogen is used by the plant and make its way to the animal, it can be released to decomposition. 

Carbon has no requirement in processing by bacteria prior to plants and animals being able to use. Plants take carbon dioxide and make it sugar, animals eat the sugar. Some of it is released carbon dioxide that we exhale.
