Adenine will only bond with one specific base in DNA strand what is it called?

Adenine only binds with Thymine, and Guanine only binds to Cytosine in DNA. In RNA however,Thymine is replaced with Uracil which binds to Adenine.

What RNA pairs with adenine?
The phosphate base that pairs with Adenine in RNA is Uracil. In a DNA strand Adenine would pair with Thymine.
What does the base in DNA molecule pair with?
The base on one strand pair with the base on the other strand, adenine with thymine, and cytosine with guanine, they join together by hydrogen bonds. Parent
Why can you predict the base sequence of one stand in a molecule of DNA if you know the sequence of the other stand?
DNA is made up four nucleotide bases,a pentose sugar and a phosphate. The four nucleotides are adenine, guanine, cytosine and thymine. Due to the nature of these molecules they fall into two groups called purines ( adenine an guanine) and pyrimidines ( cytosine and thymine). The bases have complimentary base pairing causing the double helix shape of DNA. adenine always bonds with thymjine and guanine with cytosine. So you can predict what the base sequence of one strand the other strand will be the opposite base pairing, for example if you know that a strand is AGAACTG the complimentary strand is TCTTGAC.
Why all organism have same ratio of base pair in DNA?
Organisms normally have equal amounts of the bases adenine and thymine (ratio of A:T = 1) and equal amounts of the bases cytosine and guanine (ratio C:G = 1). The reason is that there is specific base pairing ie adenine can only pair with thymine and cytosine can only pair with guanine. So in a DNA double helix, every adenine in one strand must be paired with a thymine in the other strand. Similarly, every cytosine in one strand must be paired with a guanine in the other strand. Each base pair consists of a purine and a pyrimidine. Adenine and guanine are purines and thymine and cytosine are pyrimidines. This relationship between purines and pyrimidines was discovered by Erwin Chargaff in the 1950's. See: http://en.wikipedia.org/wiki/DNA http://en.wikipedia.org/wiki/Chargaff%27s_rules
Why are there always the same number of adenine and thymine in a molecule?
Chemical analysis has shown that the number of adenine molecules in a sample of DNA is always the same as the number of thymine molecules. A sample of RNA would show that there are equal numbers of adenine molecules and uracil molecules.
What nitrogenous base does adenine pair with in an RNA strand?
Uracil.
What RNA pairs with adenine?
The phosphate base that pairs with Adenine in RNA is Uracil. In a DNA strand Adenine would pair with Thymine.
What does the base in DNA molecule pair with?
The base on one strand pair with the base on the other strand, adenine with thymine, and cytosine with guanine, they join together by hydrogen bonds. Parent
What strand of mRNA from DNA is replaced by adenine?
It's not a strand that is replaced, but a nitrogen base, much like adenine. The pyrimidine thymine is replaced by another pyrimidine uracil.
If one strand of DNA has a nucleotide base sequence of tcaggtccat?
If one strand of DNA has a nucleotide base sequence of tcaggtccat, its complementary strand is agtccaggta. Adenine pairs with thymine, while guanine pairs with cytosine.

Which RNA base bonded with the Thymine?
In RNA, the nitrogenous bases change and there is no longer Thymine, instead Uracil replaces Thymine but it bonds with the same base pair ( Adenine) as it would in DNA. In other words DNA base pairs are : Adenine- Thymine, Guanine-Cytosine. RNA base pairs are : Adenine- Uracil, Guanine-Cytosine.

How does each nucleotide differ?
All nucleotides have a 5-carbon sugar, a phosphate group, and a nitrogenous base. The bases are the differences. There are four bases in DNA: adenine, thymine, cytocine, and guanine. In RNA, the base Uracil replaces thymine. Adenine on one strand will always pair with a thymine on the other, and vice versa, while a cytosine on one strand will always pair with a guanine on the other strand. In RNA adenine will always pair with a uracil, and there is no thymine.
How do base pairing rules explain how a strand of DNA acts as a template during DNA replication?
the 4 nucleotide bases are adenine, guanine, thymidine & cytosine. In a double stranded DNA adenine always pairs with thymidine & guanine always pairs with cytosine. so knowing the base pairs in strand we can determine the base pairs of the other strand. hence DNA strand acts as a template during DNA replication.
Why are there always the same number of adenine and thymine in a molecule?
Chemical analysis has shown that the number of adenine molecules in a sample of DNA is always the same as the number of thymine molecules. A sample of RNA would show that there are equal numbers of adenine molecules and uracil molecules.
How many base pairs are present in this segment of DNA Model?
There are 2 base pairs in a DNA strand, GC and TA
