In a lab experiment, scientists are examining how different types of nucleic acids hold up under extreme environmental conditions, like high temperatures and drastic pH changes. They found that DNA kept its structure much better than RNA in these challenging situations. Given the structural and functional differences between DNA and RNA, what structural factor might explain DNA's increased stability compared to RNA?a.
The absence of the hydroxyl group on the 2' carbon of deoxyribose in DNA contributes to its greater stability compared to RNA.
b.
The lack of hydrogen bonds between the bases of DNA contributes to its greater stability compared to RNA.
c.
The lack of nitrogenous bases in DNA contributes to its greater stability compared to RNA.
d.
The absence of uracil in DNA contributes to its greater stability compared to RNA.
e.
The absence of a single-stranded structure in DNA contributes to its greater stability compared to RNA.

In one family, it was noted that a rare genetic condition, which impacts the body's ability to process a specific amino acid, has been passed down through three generations. A family tree was created to examine how this condition is inherited, revealing that it affects both males and females equally, without skipping any generations. Given this inheritance pattern and understanding that the condition arises from a recessive allele, what is the likelihood of a heterozygous couple having a child with the condition if both parents are in good health? Assume there are no new mutations taking place.
