Phosphorus is required to synthesize the deoxyribonucleoside triphosphates used in DNA replication. A geneticist grows some E. c
Harlamova29_29 [7]

Answer:

<h2> After one round: one strand of DNA  will contain radioactive 3232P, while the other strand  will not contain any radioactive phosphate. </h2><h2> After two rounds:  here 50%  of DNA will have 3232P in both strands, while 50% will contain 3232P in one strand and nonradioactive in the other strand. </h2>

 

Explanation:

1. In the initial sample which is immediately removed after addition of radioactive isotope of phosphorus ( 3232P), hence there is  no incorporation of 3232P into the DNA because replication in the medium containing 3232P has not yet occurred.  

2. After one round of replication in  radioactive isotope of phosphorus ( 3232P) containing  medium, here  only one newly synthesized strand of DNA molecule will contain 3232P, while the other strand  will not contain any  radioactive isotope of phosphorus ( 3232P),  because DNA replication occurs in semi-conservative way.

3. After two rounds of replication in medium which contains radioactive isotope of phosphorus ( 3232P), here 50% of the DNA molecules will have  radioactive isotope 3232P in both strands, while the rest 50% will contain 3232P in only one strand and nonradioactive phosphorous in the other strand.

You are a molecule of water. Choose a starting
olya-2409 [2.1K]

Answer:

In water cycle, water evaporates from the sea and oceans in the form of water vapors due to the radiation of the sun. This evaporation in the ocean is the starting point of water cycle.

Explanation:

Water cycle is also called hydrological cycle. In this cycle , water evaporates from water bodies such as rivers, seas, ponds and oceans etc. Water is also evaporated from plant bodies in the process of both evaporation and transpiration. This water moves in the form of vapors and forms clouds. These clouds moves to the land and fall on the earth surface in the form of rainfall and snowfall. From there, this water moves to the oceans through lakes and rivers and repeat the cycle again.
