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.

A.some of the genetic material is altered
38) I believe the correct answer would be letter D: ions are moved against the concentration gradient.
39) I believe the correct answer is letter A: the DNA information for development was silenced in differentiated cells. This is because the frog did not go through <span>embryonic development.</span>
Being the same species means that they can reproduce and create fertile, healthy offspring. If they are in the same species they are surely in the same family too.
