Why is the amount of guanine always equal to the amount of cytosine?
Amount of guanine is always equal to cytosine
What does Guanine equal?
Cytosine
Chargaff showed that DNA contains equal amounts of cytosine and?
guanine
Is there always going to be an equal number of guanine and cytosine nucleotides in a molecules Why?
That depends on what the molecule is. In DNA, there will be the same concentration of each, because they are paired, and DNA is a double stranded molecule. Thus, for each cytosine, there will be a guanine, and vice versa. In RNA however, it is single stranded, so the two do not have to match exactly.
The amount of guanine always equals the amout of what?
The pyrimidine cytosine (C) always pairs with the purine guanine (G) so there must always be equal amount of both in DNA.
Why is the amount of guanine always equal to the amount of cytosine?
Amount of guanine is always equal to cytosine
Which two bases are present in equal amounts in a double-stranded DNA molecule?
The two bases that are present in equal amounts in a double stranded DNA molecule are cytosine and guanine. Cytosine pairs with guanine in A DNA molecule.
What does Guanine equal?
Cytosine
What nucleotide basis are present in equal amounts of DNA?
The nucleotide bases guanine and cytosine, and adenine and thymine are present in equal quantities in DNA. This is how scientists determined that guanine pairs with cytosine, and adenine pairs with thymine.
How many Guanine's are in a DNA?
There is no consistent amount of guanine in everyone's DNA, but there is an equal amount of guanine and cytosine as well equal amounts of thymine and adenine.
Why do you think were equal parts of guanine and cytosine and equal parts of adenine and thymine in DNA of a cell?
There are equal parts of guanine and cytosine, and adenine and thymine, because they form base pairs in the DNA molecule. This is in accordance with the base-pairing rule, which states that in DNA, adenine always pairs with thymine, and guanine always pairs with cytosine.
Chargaff showed that DNA contains equal amounts of cytosine and?
guanine
What are the four nitrogen bases of DNA and how do they pair?
The four bases of RNA are adenine guanine cytosine and uracil. (Uracil is only found in RNA) The four bases of DNA are adenine, guanine, cytosine and thyamine (thyamine replaces uracil in DNA). The bases in uracil are denoted A, G, C and U. When RNA pairs with DNA, A of the DNA always pairs with U of the RNA, T of the DNA always pairs with A of the RNA, and C and G always pair with each other. If you look at a drawing of each molecule, it is easy to see that each pair of complementary bases are perfectly matched for each other. The bases pair with each other through hydrogen bonding. This is a very strong type of bond that occurs between a hydrogen and an electronegative atom (such as F, O or N). The bases are cyclic structures of carbons and hydrogens, and they have some N-H groups and carboxylic groups. So the bases of RNA pair with their complementary bases in DNA by hydrogen bonding between the N-H groups on one base with the oxygen of the carboxylic group on the complementary base.
If DNA were 40 percent cytosine what would be percent of guanine?
20% because cytosine and guanine have equal amounts. Always
The number of which base is equal to the number of guanine in a DNA molecule?
DNA contains four nucleic acid bases. These can be remembered by the acronym ACGT where the A stands for adenine, the C stands for cytosine, the G stands for guanine, and the T stands for thymine.
Why are adenine and guanine equal?
they're part of the 4 basic building blocks of DNA. the 4 are adenine, cytosine, thymine, and guanine.
Is number of adenine equal to guanine?
Based on the rule of complementary base pairing, the number (percentage) of adenine is equal to the number (percentage) of thymine, and the number (percentage) of cytosine is equal to the number (percentage) of guanine.
