DNA can copy itself easier than RNA because?
A. its a double helix
B. polymer of nucleotide
C. its confined to nucleus
D.its supported by histone proteins
I have no idea
it is a double helix, with complementary base pairs. See http://genetics.thetech.org/ask/ask24
To determine the correct answer, let's go through each option and understand its implications:
A. "DNA is a double helix." This refers to the structure of DNA, which consists of two strands that are wound around each other in a spiral. This structure indeed contributes to DNA's ability to copy itself easily. During DNA replication, the two strands unwind, and each acts as a template for the synthesis of a new complementary strand. This process is facilitated by various enzymes, such as DNA polymerases. However, while the double helix structure is important for DNA replication, it is not the only factor that makes DNA superior to RNA in this regard.
B. "DNA is a polymer of nucleotides." Both DNA and RNA are polymers of nucleotides, which are the building blocks of nucleic acids. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. While this statement is true for both DNA and RNA, it does not explain why DNA can copy itself more easily than RNA.
C. "DNA is confined to the nucleus." This option refers to the fact that DNA is primarily located within the nucleus of eukaryotic cells. Though this statement is true, it does not provide a reason why DNA can copy itself more easily.
D. "DNA is supported by histone proteins." This option refers to the association of DNA with proteins called histones. Histones help in the packaging of DNA into tightly coiled structures called chromatin. While histones are essential for DNA packaging and ensuring its structural stability, their presence does not solely account for DNA's ability to copy itself more easily.
Considering the explanations above, the most appropriate answer to the question is A. DNA's double helix structure. The double helix arrangement enables DNA replication to occur more efficiently compared to RNA's single-stranded structure. However, it is important to note that this answer does not encompass all the factors responsible for DNA's superior self-replication compared to RNA. DNA replication is a complex process involving numerous enzymes, proteins, and mechanisms that collectively contribute to its ease of replication.
