Are there always going to be an equal number of adenine and thymine nucleotide in a molecule?
yes.
Are there always going to be equal number of adenine and thymine?
Yes.
How many molecules of adenine and thymine are in each DNA model?
In DNA, adenine always pairs with thymine. Therefore, in each DNA model, the number of adenine molecules will be equal to the number of thymine molecules. The exact count of adenines and thymines will depend on the length of the DNA strand in the model.
In researching the structure of DNA Erwin Char gaff found the amount of adenine always equaled the amount of which other base?
Thymine. Discovered in the late 1940s, this is known as "The Chargaff's Rules": DNA has equal numbers of adenine and thymine residues (A = T) and an equal number of guanine and cytosine (G = C). This was one of the most important features for Watson and Crick to solve the structure of DNA molecule in 1953.
Total number of different arrangements in DNA molecule with two base pairs?
There are four different arrangements in a DNA molecule with two base pairs: adenine-thymine (A-T), thymine-adenine (T-A), cytosine-guanine (C-G), and guanine-cytosine (G-C). Each base pair can be oriented in two different ways, resulting in a total of four arrangements.
Are there always going to be an equal number of adenine and thymine nucleotide in a molecule?
yes.
Are there always going to be an equal number of adenine and thymine nucleotides an a molecule?
yes.
Are there always going to be an equal number of adenine and thymine nucleotides in a molecule why?
Yes, there will always be an equal number of adenine (A) and thymine (T) nucleotides in a DNA molecule. This is because adenine always pairs with thymine through hydrogen bonding in a double-stranded DNA molecule, following Chargaff's rule.
According to chargaffs rules which nucleotide is always paired with adenine in a DNA molecule?
Thymine is always paired with adenine in a DNA molecule according to Chargaff's rules. They form a complementary base pair, with adenine pairing with thymine through two hydrogen bonds.
Are there going a equal number of adenine and thymine nucleotides in a molecule?
Yes, please.
Are there always going to be equal number of adenine and thymine?
Yes.
What forensic scientist is trying to find out the number of adenine in the DNA sample that he obtained from a crime scene. What can he assume about the number of adenine?
The forensic scientist can assume that the number of adenine molecules in the DNA sample is equal to the number of thymine molecules, as adenine always pairs with thymine in DNA. This is known as Chargaff's rule. By determining the number of thymine molecules, the scientist can indirectly infer the number of adenine molecules present in the DNA sample.
How many molecules of adenine and thymine are in each DNA model?
In DNA, adenine always pairs with thymine. Therefore, in each DNA model, the number of adenine molecules will be equal to the number of thymine molecules. The exact count of adenines and thymines will depend on the length of the DNA strand in the model.
If adenine makes up 30 percent of the bases in a DNA helix what percentage of the bases are cystosine?
There are four bases in the DNA double helix: adenine, guanine, cytosine and thymine. An adenine in one strand always pairs with a thymine in the other strand. Similarly, a cytosine always pairs with a guanine. So the number of adenines always equals the number of thymines, and the number of cytosines always equals the number of thymines. The total number of bases must equal 100%. So if 30% of the bases are adenine, another 30% must be thymine because they always pair with each other. Thymine and adenine added together therefore make 60% of the bases. The remaining 40% must be cytosine plus guanine. If the number of cytosines must equal the number of guanines, the percentage of cytosines must be ....... well, you can work it out for yourself!
The number of hydrogen bonds between adenine and thymine in DNA is?
A double hydrogen bond binds adenine and thymine
A sample of DNA contains 500 adenine bases how many thymine bases does it contain?
If a sample of DNA contains 500 adenine bases, it will also contain 500 thymine bases. In DNA, adenine always pairs with thymine through hydrogen bonds, so the number of adenine bases will be equal to the number of thymine bases.
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.
