What type of bond holds a nucleotide together and connects each nucleotide in a DNA strand?
The backbone of the nucleotides are composed of repeating ribose (in RNA) or deoxyribose (in DNA) and phosphates held together by phosphodiester bonds between the 5's and 3's of the ribose/deoxyribose.
Atomic number of hydrogen?
Hydrogen's atomic number is 1.
What is the ratio between the number of hydrogen atoms and the number of oxygen in a disaccharide?
The ratio of oxygen to hydrogen in a polysaccharide is independent of the type of monosaccharides that it consists of. The ratio does not depend on the number of carbons in the monosaccharide. Thus, for all polysaccharide compounds the ratio of hydrogen to oxygen is 2:1.
What is the mass number of hydrogen?
The mass number of the most common hydrogen isotope, Hydrogen-1, is one
Hydrogen plus atomic number?
The atomic number of hydrogen is 1.
Are there always going to be equal number of adenine and thymine?
Yes.
According to chargaffs rules which nucleotide is always paired with adenine in a DNA molecule?
Chargaff's rules stated that the number of adenine units in a DNA segment were equal to the number of thymine units.
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.
Are there going a equal number of adenine and thymine nucleotides in a molecule?
Yes, please.
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 nucleotide in a molecule?
yes.
Are there always going to be an equal number of adenine and thymine nucleotides in a molecule why?
Yes, because the Adenine and Thymine pair with each other.
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.
What are the 4 nitrogenous bases?
There are millions of "bases" and "millions" containing nitrogen but you are probably referring to the 5 involved in De-oxyribo Nucleic Acid (DNA) and Ribo-Nucleic Acid RNA. These are the so called rungs of the ladder and for DNA are Thymine, Adenine, Cytosine and Guanine. In RNA, thymine is replaced by Uracil so this is the fifth. This is one of the fundamental differences between RNA and DNA. The other is the use of Ribose instead of Deoxy-Ribose. Amongst the viruses there are both double stranded RNA and single stranded DNA so the number of strands has nothing to do with a substance being DNA or RNA.
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.
Total number of different bases found in DNA and RNA?
Five: Thymine; Guanine; Cytosine; Adenine; Uracil
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!
