Why are hydrogen bonds so essential in the structure of DNA?

Why are hydrogen bonds so essential in the structure of DNA?

DNA has a double-helix structure because hydrogen bonds hold together the base pairs in the middle. Without hydrogen bonds, DNA would have to exist as a different structure. Water has a relatively high boiling point due to hydrogen bonds. Without hydrogen bonds, water would boil at about -80 °C.

What clues help scientists solve the structure of DNA?

What clues helped scientists solve the structure of DNA? The clues in Franklin’s X-ray pattern enabled Watson and Crick to build a model that explained the specific structure and properties of DNA.

Why are hydrogen bonds so vital to the structure of DNA 2 PT?

1. B Why are hydrogen bonds so essential to the structure of DNA? Hydrogen bonds hold the paired nitrogenous bases together. Because hydrogen bonds are weak bonds, the two strands of DNA are easily separated—a characteristic that is important to DNA’s function.

What was the experimental variable that Avery used?

What was the experimental variable that Avery used when he repeated Griffith’s work? The experimental variable in Avery’s experiment was the type of molecule-destroying enzyme he used.

What are the three key roles of DNA?

What are the three key roles of DNA? DNA must store, copy, and transmit information. Why would the storage of genetic information in genes help explain why chromosomes are separated so carefully during mitosis?

What creates a hydrogen bond?

Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.

Why did Hershey and Chase grow viruses in cultures?

Why did Hershey and Chase grow viruses in cultures that contained both radioactive phosphorus and radioactive sulfur? Hershey and Chase used both radioactive phosphorus and radioactive sulfur. This was a clever strategy since they knew that protein contained almost no phosphorus and DNA contains no sulfur.

What conclusion did Hershey and Chase make?

Hershey and Chase concluded that protein was not genetic material, and that DNA was genetic material.

What is the main function of DNA in a cell?

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
