A double-stranded DNA molecule contains a total of 120 purines and 120 pyrimidines This DNA molecule could be composed of?
I don't really understand the point of the question but let's see what we can do.
Purines are Adenine and Guanine
Pyrimidines are Tyimine and Cytosine
Since A pairs with T and G pairs with C, the molecule can be composed of any number of ACTG where
A+G=C+T=120
and
A=T and G=C
Hope that helps.
What else can I help you with?
How many purines and pyrimidines are present in the DNA molecule?
There are two purines (adenine and guanine) and two pyrimidines (cytosine and thymine) present in the DNA molecule.
How many resonance structures of pyrimidines are there?
There are three resonance structures of pyrimidines. These structures involve the delocalization of electrons within the aromatic ring of the molecule, leading to different arrangements of double bonds.
What is the term for a molecule composed of two or more different elements?
The term for a molecule composed of two or more different elements is called a compound.
What is any molecule that contains hydrogen and carbon?
Any molecule that contains hydrogen and carbon is an organic compound. If the molecule contains no other elements, it is also a hydrocarbon.
What is a molecule composed of two of the same element?
A molecule composed of two of the same element is called a diatomic molecule. Examples include oxygen (O2) and nitrogen (N2), where two atoms of the same element bond together to form a stable molecule.
How many purines and pyrimidines are present in the DNA molecule?
There are two purines (adenine and guanine) and two pyrimidines (cytosine and thymine) present in the DNA molecule.
What macro molecule has pyrimidines and purines?
Nucleic acids
How many rings do pyrimides have?
Pyrimidines have a single ring in their molecule.
What is the relative percentage of purines to a pyrimidines in a DNA molecule?
In a DNA molecule, the relative percentage of purines (adenine and guanine) to pyrimidines (cytosine and thymine) is approximately 1:1. This means that purines make up roughly 50% and pyrimidines make up the other 50% of the bases in DNA.
What are the two kinds of nucleic acid's?
a There are two types of nucleic acids. Purines and Pyrimidines. Purine contains 1) Adenine 2) Guanine. Pyrimidines contains 1)Cytosine 2) Thymine 3)Uracil. Out of this Uracil replaces Thymine in RNA molecule. DNA contains 1) Adenine 2) Guanine 3)Cytosine 4)Thymine.
How can an atom not be a molecule?
A molecule is composed of one or more atoms that are properly bonded to each other. If a molecule contains more than one atom, each atom is then a partial molecule as opposed to a whole molecule. Therein lies the difference.
How many resonance structures of pyrimidines are there?
There are three resonance structures of pyrimidines. These structures involve the delocalization of electrons within the aromatic ring of the molecule, leading to different arrangements of double bonds.
What is composed of only one type of molecule?
What is composed of only one type of molecule
When does the shape of a molecule affect it's polarity?
when the molecule contains polar bonds
What molecule never contains a phosphate group?
Quite a few fit that description (including water, carbon dioxide, borane etc.)
What is the formula of a triatomic ozone molecule that contains only oxygen?
O3, what did you think? There is only one ozone.
How many atoms is a molecule composed of?
A molecule is composed of a specific number of atoms that are bonded together in a unique arrangement. The number of atoms in a molecule varies depending on the chemical formula of the molecule.
