Even though DNA and messenger RNA share many characteristics, they are different in both structure and function. Describe how DN
Akimi4 [234]

Answer/Explanation:

DNA and messenger RNA (mRNA) are different in a variety of ways that impact their function in the cell. One way in which they are different is their location. DNA is found in the nucleus of the cell, whereas mRNA is produced in the nucleus, but moves to the cytoplasm.

They are also different in terms of their structure. The mRNA molecule is single-stranded, whereas DNA is double stranded, forming a helix. Their composition is also slightly different, DNA uses the nucleotides adenine, thymine, cytosine and guanine, whereas RNA uses uracil in place of thymine.

Finally, they differ in their function. The function of DNA is to hold the genetic information and transmit it to future generations. The function of mRNA is to transcribe the information encoded in DNA and pass it to the protein synthesis machinery, where mRNA is translated to proteins.

therapeutic cloning is duplicating part of a person e.g, a heart or liver,or even just a few cells true or false?
Trava [24]

Answer:

True.

Explanation:

Therapeutic cloning is the technique of using cloning procedures to generate embryonic stem cells that can be applied for the damaged organ or tissue replacement without getting the chances of any rejection. This can be achieved by putting a diploid nucleus from a body cell to a enucleated cell.  Then from that cell an identical organ can be developed.

A good example of homeostasis would be: darkening a room makes it easier to sleep. ingesting too much alcohol leads to vomiting.
solmaris [256]
Homeostasis is a self-regulating technique by which systems in the body maintain stability and tend to adjust to optimal conditions which are essential for survival. Thereby, the role of homeostasis is to help the body maintain constant internal environment. A good example of homeostasis would be ‘drinking excess alcohol causes vomiting’.
