How is DNA copied?

Biology
1 answer:
Sedaia [141]3 years ago
3 0

Answer:

The DNA is copied by B: The sense strand of DNA is used as a template to create both strands of the new double helix.

Explanation:

Ok, the DNA is "copied" in the tanscription process. The transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). Also, the DNA safely stores genetic material.

During the process of transcription a single strand of RNA is synthesized using a double stranded DNA molecule as a template.  The two strands of the DNA molecule are separated from one another, exposing the nitrogenous bases. Only one strand is actively used as a template in the transcription process, this is known as the sense strand, or template strand. The complementary DNA strand, the one that is not used, is called the nonsense or antisense strand.

Sarah recently learned that O2 is found in the Earth’s water bodies. She was amazed to know the proportion of O2 found in the oc
Mamont248 [21]

It has been found that the rainforests are accountable for about one-third, that is, 28 percent of the oxygen of the Earth, however, the majority of the oxygen, that is, about 70 percent in the atmosphere is generated by the marine plants. The left-over two percent of the oxygen comes from other sources.  

The majority of the oxygen comes from the tiny plants in the ocean known as phytoplankton, which lives near the surface of the water and drifts with the currents. Similarly to plants, they perform the process of photosynthesis, that is, they utilize carbon dioxide and sunlight to prepare food, oxygen is the by-product of photosynthesis.  

However, the concentration of the dissolved oxygen, which the water can hold relies on the salinity and temperature of the water. The cold water can withhold more oxygen in comparison to warm water and fresh water can hold more oxygen in comparison to salt water. So, the warmer and saltier the water is, the less will be the oxygen dissolved in it.

disease A. That is option D.

<h3>Health statistics of Country Z</h3>

Health statistics is used by professionals to summarize the health status or information on the health of individuals in a particular geographical location.

The basic statistic tools that can be used to check the health status of a population are,

  • prevalence

  • Case fatality ratio

The prevalence rate is the total number of cases of a disease existing in a population divided by the total population.

The prevalence rate of disease A = 225 per 100,000 population while the prevalence rate of disease B = 500 per 100,000 population.

Therefore, the burden of diseases A and B in country Z is that Disease B has a higher prevalence than

disease A.
