Answers

When a cell divides, it is important that each daughter cell receives an identical copy of the DNA. ... This model for replication suggests that the two strands of the double helix separate during replication, and each strand serves as a template from which the new complementary strand is copied

Answer from: torybobadilla

To synthesise new DNA and RNA

Explanation:During replication, DNA strands are separated from each other by helicase enzyme. These two separated strands act as a template strand. From the template, new DNA strands synthesised in opposite directions. The one strand synthesized continuously, called the leading strand and the other strand synthesized small fragments of DNA. This is a discontinuous process and the strand call lagging strand. The smaller fragments of DNA are called Okazaki fragments. The DNA polymerase adds new nucleotides and it is initiated by RNA primase in the template strands. This RNA primase later separates from the lagging strand and forms mRNA which comes to the cytoplasm from the nucleus. In this way, the original DNA strands form new DNA strands and the RNA.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
