A student mixes various molecules needed for DNA replication. When he adds DNA, replication occurs, but each DNA duplex consists
weeeeeb [17]

Answer: DNA Ligase

Explanation:

During DNA replication, both the parental DNA strands are separated and act as templates for the synthesis of new strands. The formation of the new strands occurs in only 5'-3' direction and thus both the strands are synthesized in a different manner. One new strand with the template of 3'-5' direction will be synthesized continuously and is called a leading strand. The other strand with the template of 5'-3' direction will be synthesized discontinuously in the form of DNA fragments. These fragments are called Okazaki fragments and the strand is called a lagging strand. DNA ligase connects these fragments later to form a continuous lagging strand.

Therefore, DNA ligase is required for ligation of Okazaki fragments, and in absence of DNA ligase, the ligation of fragments will not occur and the newly synthesized strand will be discontinuous. However, if DNA ligase is not present in the reaction mixture, then the chances are that not all the newly synthesized DNA strands will be discontinuous. Only the DNA molecule with the lagging strand will be in the form of fragments.

The relative humidity would be ________% if the actual water vapor in the air was 10 grams per cubic meter, the air's capacity t
lys-0071 [83]

Answer: The Relative humidity is 50%

Explanation: Relative humidity is the ratio of the air’s water vapour content (the actual amount of water vapour in the air) to its water vapour capacity at a given temperature. It depends on temperature and the pressure of the system of interest and it is usually expressed in PERCENTAGE; the higher the percentage, the more humid the air/water mixture.

The formula of Relative humidity (%) = (water vapor content / water vapor capacity) x 100%

Where: Water vapour content is the actual amount of water vapour in the air. Which is 10g/cm³ from the question above;

Water vapour capacity is the air's capacity to hold water vapour. Which is 20g/cm³ from the question above.

Therefore, RH(%)= (10g/cm³ / 20g/cm³) x 100 = 0.5 x 100= 50%

This means that the air contains half of the water vapour it could hold at 20 degree Celsius.
