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
No problem! I'm here to help.
The correct answer is A. DNA is able to copy itself more easily than RNA because it exists as a double helix structure. Let me explain further:
DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are both types of nucleic acids that play fundamental roles in storing and transmitting genetic information in living organisms.
The structure of DNA is a double helix, which means it consists of two strands that are twisted around each other like a twisted ladder. Each strand is made up of a long chain of nucleotides. A nucleotide is composed of three parts: a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine).
The unique feature of DNA's double helix structure is that the two strands are complementary to each other. This means that the nucleotide bases on one strand match up with specific bases on the other strand. Adenine (A) always pairs with thymine (T) and cytosine (C) always pairs with guanine (G).
When DNA needs to be copied, the double strands separate, and each strand serves as a template for the synthesis of a new complementary strand. This process is known as DNA replication. Each new DNA molecule contains one original strand and one newly synthesized strand, resulting in two identical copies of the original DNA.
In contrast, RNA does not have a double helix structure. RNA is usually single-stranded, although it can fold back on itself to form secondary structures. The lack of a double helix structure in RNA makes it less stable and more prone to degradation. Additionally, RNA is involved in a wide range of functions in the cell, including protein synthesis, gene regulation, and enzymatic activities.
Therefore, the correct answer to the question is A. DNA can copy itself more easily than RNA because of its double helix structure, which allows for efficient and accurate replication of the genetic information.
