Part A Which of the following statements best summarizes the differences between DNA and RNA? Which of the following statements
best summarizes the differences between DNA and RNA? DNA contains the base uracil, whereas RNA contains the base thymine. DNA encodes hereditary information, whereas RNA does not. The bases in DNA contain sugars, whereas the bases in RNA do not contain sugar. The bases in DNA contain sulfur, whereas the bases in RNA do not contain sulfur. DNA nucleotides contain a different sugar than RNA nucleotides.
DNA nucleotides contain a different sugar than RNA nucleotides.
Explanation:
DNA (Deoxyribose nucleic acid) and RNA (ribonucleic acid) are the nucleic acids which act a hereditary material in the genome of the organisms. The main difference that lies in the structure of DNA and RNA is that they exhibit different sugars.
DNA consists of sugar which is called as deoxyribose while the RNA structure consists of the ribose sugar. The only difference between the dioxyribose and ribose is that one more hydroxyl or -OH group is present in RNA at the the second (2') carbon ring. The deoxyribose sugar exhibit hydrogen or -H group attached to the second (2') carbon ring.
The correct answer is- DNA nucleotides contain a different sugar than RNA nucleotides.
Explanation:
DNA and RNA are both nucleic acid structures and every organism contains one of them as the genetic material. There is a difference between DNA and RNA. The sugar that is used to make DNA is deoxyribose sugar which lacks the hydroxyl group at 2nd carbon position so only H atom is present there.
While in the formation of RNA ribose sugar is added which has a hydroxyl group at both the 2nd and 3rd carbon position of the sugar. There is one more difference in DNA and RNA uracil is present in RNA rather than thymine.
So the right answer is- DNA nucleotides contain a different sugar than RNA nucleotides.
If Bb gene is crossed with Bb, the offspring is produced with normal hearing because both the genes are recessive in which the deafness gene hide and the hearing gene is dominant so the offspring can hear sounds clearly. The dominant A gene is responsible for deafness and we can see the offspring BbxBb in which no dominant gene is present. The other three offspring are deaf because of the presence of dominant A gene in their genetic makeup.
