Bases Holding Two Single Strands Of Dna Together Into A Double Strand Of Dna Interact Through __________

1. What kinds of bonds holds two strands of a DNA molecule together?

Oct 20, 2016 · The two strands of a DNA molecule are held together by hydrogen bonds between the nitrogen bases on opposite strands.
The two strands of a DNA molecule are held together by hydrogen bonds between the nitrogen bases on opposite strands.

Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.
Biologists in the 1940s had difficulty in accepting DNA as the genetic material because of the apparent simplicity of its chemistry. DNA was known to be a long polymer composed of only four types of subunits, which resemble one another chemically. Early in the 1950s, DNA was first examined by x-ray diffraction analysis, a technique for determining the three-dimensional atomic structure of a molecule (discussed in Chapter 8). The early x-ray diffraction results indicated that DNA was composed of two strands of the polymer wound into a helix. The observation that DNA was double-stranded was of crucial significance and provided one of the major clues that led to the Watson-Crick structure of DNA. Only when this model was proposed did DNA's potential for replication and information encoding become apparent. In this section we examine the structure of the DNA molecule and explain in general terms how it is able to store hereditary information.

A codon is a segment (or piece) of double stranded DNA that is three nucleotides long. A gene can be thought of as many three-nucleotide codons strung together.

Hydrogen-bond interactions between the bases allow two strands of DNA to form the double helix. These interactions are specific: A base pairs with T, and C base ...
DNA, or deoxyribonucleic acid, is the heritable material found in all cells. DNA provides the instructions to build, maintain, and regulate cells and organisms and is passed on when cells divide and when organisms reproduce. In this unit, the molecular structure of DNA and its packaging within cells will be examined. In 1953, using data obtained by Rosalind Franklin, James Watson and Francis Crick determined that DNA exists in a form known as the double helix. A helix is a winding structure like a corkscrew; DNA is known as a double helix because there are two intertwined strands within each molecule of DNA.

The hydrogen bonds between the base pairs form the double helical structure of DNA. There is no exchange or sharing of electrons in hydrogen bonds as seen in ...
There are several interactions present within a strand (intrastrand interactions) and between two strands (interstrand) that stabilize DNA.
