Are hydrogen bonds in DNA weak or strong?
Hydrogen bonds in DNA are relatively weak, but they are crucial for maintaining the double helix structure of the DNA molecule. These bonds are formed between complementary base pairs (adenine-thymine and guanine-cytosine) and help stabilize the overall structure of the DNA molecule.
What role does a bond play in the structure of DNA?
A bond in DNA helps hold the structure together by connecting the nucleotide bases in the double helix. These bonds are essential for maintaining the stability and integrity of the DNA molecule.
Number of phosphates in DNA molecule with five base pairs?
A DNA molecule with five base pairs would have 5 phosphate groups in its backbone. Each nucleotide in the DNA molecule contains one phosphate group, so a DNA molecule with five base pairs would have a total of 5 phosphate groups in its structure.
Watson and crick deduced the structure of this molecule?
Watson and Crick deduced the double helix structure of DNA. They proposed this model in 1953, revolutionizing our understanding of genetics and molecular biology.
What is the significance of adenine numbering in the context of DNA structure and function?
The numbering of adenine in DNA is important for identifying its position in the DNA molecule. This numbering system helps scientists understand the structure and function of DNA, as well as how adenine interacts with other molecules in the cell.
What best describes the structure of DNA molecule?
A double helix of two strands of DNA linked together with sugar-phosphate backbones with bases on the inside.
Which term most accurately describes the shapes of a DNA molecule?
DNA are double helical spiral molecules. Structure was discovered by Watson and Crick
DNA is typically found in cells in the form of a very long strand that is coiled many times and contains thousands or millions of nitrogen bases Which term best describes this very long molecule of D?
The term that best describes this very long molecule of DNA is a double helix. This structure consists of two intertwined strands of nucleotides, forming a twisted ladder shape.
which best describes the structure of dna molecule?
Answer:Two strands of DNA link together
Which best describes the structure of a DNA molecule-?
a double helix- apex
What is the term which describes the fact that half of the old DNA molecule is kept in new molecule?
The term that describes the process where half of the old DNA molecule is retained in the new DNA molecule during DNA replication is known as semi-conservative replication. This means that each new DNA molecule formed consists of one original strand and one newly synthesized complementary strand.
Three thing make the structure of a DNA molecule?
The structure of a DNA molecule is made up of three things: a sugar-phosphate backbone, nucleotide bases (adenine, thymine, cytosine, and guanine), and hydrogen bonds that form between the bases. These components form the double helix shape of the DNA molecule.
what Describe the structure of the DNA molecule?
a DNA molecule is made up of a phosphate, sugar and base A double Helix Strand
What is the role of deoxyribose in DNA structure and function?
Deoxyribose is a sugar molecule that forms the backbone of DNA. It helps to stabilize the structure of the DNA molecule and plays a crucial role in storing and transmitting genetic information.
What type of sugar does DNA contain, and how does it contribute to the structure and function of the molecule?
DNA contains deoxyribose sugar. This sugar contributes to the structure of the DNA molecule by forming the backbone of the double helix structure. It also plays a role in stabilizing the molecule and facilitating the pairing of complementary nucleotide bases, which is essential for DNA replication and protein synthesis.
How did Watson and crick describes the structure of DNA?
it was in strands
Is deoxyribose present in DNA and what role does it play in the structure and function of the molecule?
Yes, deoxyribose is present in DNA. It is a sugar molecule that forms the backbone of the DNA structure. Deoxyribose helps to stabilize the DNA molecule and provides a framework for the attachment of the nitrogenous bases, which are essential for encoding genetic information.
