Enzymes that open the double helix by breaking hydrogen bonds between nitrogen bases is what?
Helicase.
What are examples of covalent bonds besides water?
Single, double, and triple carbon-carbon bonds; carbon-hydrogen bonds; carbon-halogen bonds; hydrogen-hydrogen bonds; nitrogen-nitrogen bonds; single and double carbon-oxygen bonds; silicon-oxygen bonds in silicone polymers.
What is nitrogen bases role in DNA?
the hydrogen bonds btw nitrogenous bases leads to stability of the double helix
What type of chemical bond does nitric acid have?
Nitric acid, HNO3 has covalent bonds. Two nitrogen-oxygen single bonds, one nitrogen-oxygen double bond and an oxygen-hydrogen single bond. There is a formal +1 charge on the nitrogen center, and a formal -1 charge on the single-bonded oxygen without the hydrogen atom.
What type of bond holds together 2 strands of DNA?
Hydrogen bonding holds together the two strands of a double stranded DNA. Hydrogen bonding exists between the nitrogen base pairs.
What are helicases?
a class of organaic moleicules, each having a double ring of carbon and nitrogen atoms
Enzymes that open the double helix by breaking hydrogen bonds between nitrogen bases is what?
Helicase.
How do helicases unwind a double helix?
Helicase uses free energy from ATP to break the hydrogen bonds between the double helix of the DNA. It breaks the bonds between adenine and thymine, and guanine and cytosine. This unzips the double helix structure.
The nitrogen base pairs in double stranded DNA are connected by?
hydrogen bonds
What holdes nitrogen bases together?
A weak hydrogen bond, adenine and thymine have a double hydrogen bond cytosine and guanine have a triple hydrogen bond
What are examples of covalent bonds besides water?
Single, double, and triple carbon-carbon bonds; carbon-hydrogen bonds; carbon-halogen bonds; hydrogen-hydrogen bonds; nitrogen-nitrogen bonds; single and double carbon-oxygen bonds; silicon-oxygen bonds in silicone polymers.
What are some examples of covalent bond?
Single, double, and triple carbon-carbon bonds; carbon-hydrogen bonds; carbon-halogen bonds; hydrogen-hydrogen bonds; nitrogen-nitrogen bonds; single and double carbon-oxygen bonds; silicon-oxygen bonds; nitrogen-oxygen bonds; etc.
Hydrogen bonds are found in DNA?
yes, hydrogen bonds are what connects the double helix together. hydrogen bonds for between the nitrogen bases on each DNA strand. nitrogen bases are: - Cytosine (C) - Thymine (T) - Guanine (G) - Adenins (A)
What enzymes unwinding DNA double helix by breaking the hydrogen bonds to separate the complementary strands?
Helicase
What does helicase do in replication?
(Apex) It breaks apart the bases.
What is nitrogen bases role in DNA?
the hydrogen bonds btw nitrogenous bases leads to stability of the double helix
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.
