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.
What else can I help you with?
What did chargraff discover about the frequency of the nucleotides?
Chargaff discovered that in DNA, there is a 1:1 ratio of adenine and thymine, and a 1:1 ratio of guanine and cytosine. This led to the rule that adenine always pairs with thymine and guanine always pairs with cytosine.
What in DNA always forms bonds with guanine?
cytosine (C).
What are nucluetides in DNA?
Nucleotides are the building blocks of DNA, consisting of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). They are linked together through phosphodiester bonds to form the DNA double helix structure.
Which bases always pair on DNA?
Adenine pairs with thymine and guanine pairs with cytosine
Why is the amount of guanine always equal to the amount of cytosine?
Guanine and cytosine always pair together due to specific hydrogen bonding interactions that stabilize their association in the DNA double helix. This base pairing rule is known as Chargaff's rule, where the amount of guanine is always equal to the amount of cytosine in a DNA molecule.
What nitrogen base always pairs up with adenine?
adenine with thymine cytosine with guanine adenine with uracil cytosine with guanine
DNA's long chains of paired nucleotides are made up of what?
DNA's long chains of paired nucleotides are made up of four different nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G). These nucleotides are paired together in specific combinations (A with T, and C with G) to form the double helix structure of DNA.
What always pairs with cytosine?
cytosine pairs with guanine and thymine pairs with adenine.
What did chargraff discover about the frequency of the nucleotides?
Chargaff discovered that in DNA, there is a 1:1 ratio of adenine and thymine, and a 1:1 ratio of guanine and cytosine. This led to the rule that adenine always pairs with thymine and guanine always pairs with cytosine.
In dna guanine pairs with?
In DNA Guanine always pairs with Cytosine (C) cytosine (C) guanine (G) thymine (T) adenine (A)
Are there always going to be an equal number of guanine and and cytosine nucleotides in a molecule?
Yes, if all is normal.
What in DNA always forms bonds with guanine?
cytosine (C).
What are the rungs steps of a DNA molecule made of?
The 'steps' or 'rungs' of the DNA 'ladder' are complimentary pairs of bases bonded by hydrogen bonds. The bases are Adenine, Thymine, Cytosine and Guanine. Adenine always bonds to Thymine and Cytosine always bonds to Guanine.
What molecules make up DNA molecule?
The backbone of DNA is sugar/phosphate, the little bars in it are called bases that always match up like this: Adenine-Thymine Cytosine-Guanine
Which nucleotide base will always link to cytosine?
Guanine
