What is one reason that there are very few errors in DNA replication?

Biology
1 answer:
Dima020 [189]3 years ago
7 0

Answer: The reason is because DNA polymerase which is the enzyme that catalyzes the synthesis of DNA has a 3'->5' exonuclease activity that double-checks each nucleotide after it is added.

Explanation: The 3'->5' exonuclease activity of DNA polymerase allows the enzyme to double-check and remove a newly added wrong nucleotide. It is highly specific for mismatched base pairs. When the DNA polymerase adds a wrong nucleotide to the growing strand, translocation of the enzyme to the position where the next nucleotide is to be added is halted, but the exonuclease activity of the DNA polymerase removes the incorrectly paired nucleotide so that replication can continue. The process of double-checking a newly added nucleotide and removal of any incorrectly paired nucleotide by the DNA polymerase is called proofreading.

Animals cannot make their own food.

Explanation:

An example of the physiological capabilities of plants is their ability to make food on their own using the energy from the sun and chemical substances in the environment, animals do not make their own food.

  • Physicological ability refers the body functions of an organism. It refers to the life biochemical processes a body is able to carry out based on its design.
  • Metabolism is a living function attributable to all life.
  • Organisms can either build up energy such as seen in plants during photosynthesis. This process is called anabolism.
  • Some other organisms, makes use of the energy in their own life process and this is a catabolic process.

Rachel drove 300 miles from her home to Philadelphia to visit her sister and then returned home a week later. At the end of the
statuscvo [17]

Answer:

The correct answer would be - zero miles, 600 miles.

Explanation:

She started from the same point and after the trip, she ended it on the same point in Philadelphia therefore the displacement is expected to be zero.

The distance she traveled would be 2 into 300 miles as she traveled to her sister and traveled back from there so

Distance = 2*300

= 600 miles.

Thus, the correct answer would be - 0 and 600 miles.
