What is a double helix DNA or RNA?
A double helix is a twisted ladder-like structure that describes the shape of DNA. DNA is a molecule that carries genetic information in organisms. RNA is another type of nucleic acid that can form double helix structures under certain conditions, but it is less stable in this form compared to DNA.
What does it mean to have double stranded DNA and how does it differ from single stranded DNA?
Having double stranded DNA means that the DNA molecule consists of two strands that are twisted together in a double helix structure. This is the typical structure of DNA found in living organisms. Single stranded DNA, on the other hand, consists of just one strand of DNA. Double stranded DNA is more stable and less prone to errors during replication compared to single stranded DNA.
Is RNA structured as a double helix?
No, RNA is not structured as a double helix like DNA. RNA is typically single-stranded and can fold into various shapes and structures to carry out its functions in the cell.
Why is DNA shaped like a double helix?
DNA is shaped like a double helix because this structure allows it to store genetic information in a compact and stable way. The double helix shape helps protect the genetic code and allows for easy access when needed for processes like replication and protein synthesis.
How does DNA form a double helix structure?
DNA forms a double helix structure through the pairing of complementary nucleotide bases. Adenine pairs with thymine, and guanine pairs with cytosine, creating a stable and twisted ladder-like structure. This pairing is held together by hydrogen bonds, resulting in the iconic double helix shape of DNA.

What is the difference between single gene DNA and repetitive sequences of DNA?
DNA is double Helix But A Gene is a part of that double helix.

what is the shape of a DNA?
double helix
If a DNA double helix is gradually heated which bonds in the molecule will break first?
As a DNA double helix is gradually heated, the hydrogen bonds between the complementary base pairs will break first. These bonds are weaker compared to the covalent bonds that hold the sugar-phosphate backbone together. As the temperature increases, the stability of the hydrogen bonds decreases, leading to the unwinding of the double helix before the more stable covalent bonds are affected.
What is a single helix molecule?
A single helix molecule is a molecule that has a spiral shape resembling a single coil or spring. One common example is the DNA molecule, which consists of a single helix structure formed by its two intertwined strands.
Why is DNA a more stable genome repository than RNA?
Because DNA forms a double helix.
What is the shape of the DNA molecule known as?
Double Helix :D
Is a DNA a single stranded?
DNA is a double helix structure like a twisted ladder
Is RNA structured as a double helix?
No, RNA is not structured as a double helix like DNA. RNA is typically single-stranded and can fold into various shapes and structures to carry out its functions in the cell.

Why cant RNA form a double helix?
RNA typically does not form a double helix like DNA due to its structural characteristics. RNA is usually single-stranded and has ribose sugar, which contains an additional hydroxyl group that makes it more reactive and less stable than DNA's deoxyribose. While RNA can form secondary structures such as loops and hairpins through intramolecular base pairing, the presence of this extra hydroxyl group and the single-stranded nature generally prevent it from adopting a stable double helical structure like that of DNA.
