What is the nitrogeneous base containing 2 carbon rings?
purines
How many nitrogenous bases are there What are they called?
Four, out of whish 2 purines and two pyremidines
How many rings does a purine have?
A purine has two rings in its structure: a six-membered ring fused to a five-membered ring.
Why are thymine and cytosine are called pyrimidines?
Thymine and cytosine are called pyrimidines due to their chemical structure, which includes a six-membered nitrogen-containing ring with two nitrogen atoms. Pyrimidines are one of the two main types of nitrogenous bases found in DNA and RNA, the other being purines.
What is the diameter of the DNA double helix?
Purines always bond with Pyrimidines.
The two sides of the dna molecule are held together by what?
Hydrogen bonds between the purines and pyrimidines. A and T form 2 hydrogen bonds, and G and C form three.
What type of bonding exists between particular purines and pyrimidines in DNA?
adenine and thymine are bonded by 2 hydrogen bonds and cytosine and guanine are bonded by 3 hydrogen bonds
What substance make up a DNA molecule?
The DNA is the longest biopolymer discovered. It is made up of two strands that are the polymers of repeating units of deoxyribonucleotides. The deoxyribonucleotides, themselves consist of three moieties: 1. Deoxyribose Sugar: A pentose (5 carbon) Sugar 2. Phosphate: Phosphate group imparts the negative charge to DNA molecule 3. Nitrogenous Bases: These are aromatic compounds that have their basic nature due the presence of Nitrogen. Two types of bases are found in the DNA molecule 1. Pyrimidine: they are single ringed compounds that are derivative of compound called Pyrimidine. There are two types of Pyrimidines in DNA, Cytosine and Thymine. 2. Purines: Purines are derivative of organic compounds called as Purines and have two rings. There are two Purines: Adenine and Guanine) in DNA. The dexoribonucleotides are linked by the reaction of Phosphodiester bond to form one strand of DNA>
What are the pairs of DNA?
In base-pairing rules by Watson and Crick, the nitrogenous bases Adenine(A) base pair with Thymine(T), and Guanine(G) base pair with Cytosine(C) in the DNA. They are called nitrogenouse bases as they contain nitrogen atoms. There are 2 types of bases- purines and pyrmidines. Purines like A and T have fused 5- and 6- member rings. Pyrimidines like G and C have one six member ring. Adenine - Thymine Cytosine - Guanine
Is durum wheat good for gout patient?
Durum wheat is a whole grain rich in fiber and nutrients, which can be beneficial for overall health. However, individuals with gout should moderate their intake of high-purine foods like durum wheat to help manage their condition, as purines can contribute to increased uric acid levels and gout flare-ups. It's recommended to consult a healthcare provider or a registered dietitian for personalized dietary recommendations.
What is the name for ch3chclch2ch3?
The name for CH3CHClCH2CH3 is 2-chloropropane.
What is the name for 2 to the 4th power?
24 = (2 x 2 x 2 x 2) = 16. Its name is "Sixteen".
