What type of bond occurs between the nitrogenous bases?
Hydrogen bonds occur between the nitrogenous bases in DNA. These bonds are relatively weak and allow the bases to pair up in specific combinations (A-T and C-G) to form the double helix structure of the DNA molecule.
What type of bond keeps the bases paired toghter?
Hydrogen bonds are the type of bond that keeps the bases paired together in a DNA molecule. These bonds form between the complementary bases adenine-thymine and guanine-cytosine.
What type of bond holds bases together?
Hydrogen bonds hold bases together in DNA. These bonds form between the nitrogenous bases adenine (A) and thymine (T), and between cytosine (C) and guanine (G), helping to stabilize the DNA molecule's double helix structure.
What are the parts of a nitrogenous base?
A nitrogenous (nitrogen-containing) base is a nitrogen-containing molecule having the chemical properties of a base. It is an organic compound that owes its property as a baseto the lone pair of electrons of a nitrogen atom. In biological sciences, nitrogenous bases are typically classified as the derivatives of two parent compounds, pyrimidine and purine.They are non-polar and due to their aromaticity, planar. Both pyrimidines and purines resemble pyridine and are thus weak bases and relatively unreactive towards electrophilic aromatic substitution. Their flat shape is particularly important when considering their roles in nucleic acids as nucleobases (building blocks of DNA and RNA): adenine, guanine,thymine, cytosine, and uracil. These nitrogenous bases hydrogen bond between opposing DNA strands to form the rungs of the "twisted ladder" or double helix of DNA or a biological catalyst that is found in the nucleotides. Adenine is always paired with Thymine, and Guanine is always paired with Cytosine.
What type of bonding do the nitrogenous bases form?
Nitrogenous bases form hydrogen bonds with one another. These hydrogen bonds are responsible for holding the two strands of DNA together in the double helix structure.
What pairs of molecules form the steps in the DNA molecule?
nitrogenous bases
What type of bonds form between the nitrogenous bases of a DNA molecule?
Hydrogen bonds form between the nitrogenous bases of a DNA molecule. These hydrogen bonds connect adenine with thymine (or uracil in RNA) and guanine with cytosine, contributing to the double helix structure of DNA.
What type of bond occurs between the nitrogenous bases?
Hydrogen bonds occur between the nitrogenous bases in DNA. These bonds are relatively weak and allow the bases to pair up in specific combinations (A-T and C-G) to form the double helix structure of the DNA molecule.
Sugar phosphate and what make up the DNA molecule?
Nitrogenous bases, such as adenine, thymine, cytosine, and guanine, along with sugar phosphate groups, make up the DNA molecule. These nitrogenous bases are paired together to form the characteristic double helix structure of DNA.
What make up the rugs of the DNA molecule?
The DNA molecule is composed of nucleotides, which consist of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). These nucleotides join together in a specific sequence to form the double helix structure of the DNA molecule.
What type of bonds holds the nitrogenous bases together in the DNA molecule?
your teacher will probably accept hydrogen bonds, however it is more of an attraction not a physical bond
Where do hyrdrogen bonds form in the DNA molecule?
across the nitrogenous bases, they form between the complementary base pairs Thymine and Adenine and also cytosine and guanine
Which pair of nitrogen bases will form a bond in a DNA molecule?
The two chains are connected by hydrogen bonding between nitrogen bases to form a long double-stranded molecule.So hydrogen bonding determines which nitrogen bases form pairs of DNA.
What makes up the middle of a DNA molecule?
The middle of a DNA molecule consists of nitrogenous bases (adenine, thymine, cytosine, and guanine) that pair up to form the genetic code. These bases are connected by hydrogen bonds, forming the double helix structure of DNA.
Which bond does not form a molecule?
h20 does not form a bond
What are the two main sections of the DNA molecule?
The two main sections of the DNA molecule are the sugar-phosphate backbone and the nitrogenous bases. The sugar-phosphate backbone consists of alternating sugar and phosphate molecules that form the structural backbone of the DNA molecule. The nitrogenous bases (adenine, thymine, cytosine, and guanine) are connected to the sugar molecules and form the internal structure of the DNA molecule through complementary base pairing.
What kind of bond holds the two strands of the double helix together?
Hydrogen bonds that form between the nitrogenous bases hold the double helix together.
