Hey friend!
Let's figure this out!
DNA replication is the process by which DNA makes a copy of itself during cell division. The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA molecule. DNA replication is self-complementary, and it does not need a third party. The two strands of a DNA act as parents and work as a template to synthesize the two daughters of DNA. According to an estimate, there are nearly 3 billion DNA bases in our genome, and during DNA replication they all replicate. Mutation can cause changes in DNA bases only, but it can be one or even more than one basis.<span>

A 70-year-old client with a diagnosis of left-sided stroke is admitted to the facility. To prevent the development of disuse osteoporosis, which objective is most appropriate?
a) Promoting range-of-motion (ROM) exercises
b) Promoting weight-bearing exercises
c) Maintaining protein levels
d) Maintaining vitamin levels
Answer: b) Promoting weight-bearing exercises
Explanation:
The bone is a living tissue that becomes stronger with exercise. Weightlessness and immobility can lead to bone loss.
Weight-bearing exercises are those that force us to work with gravity, like walking, hiking, jogging, climbing stairs, playing tennis, and dancing. They can help prevent disuse osteoporosis.
On the other hand, swimming and bicycling would be examples of non-weight-bearing exercises.
