Basic structure of DNA or deoxyribonucleic acid: A nucleotide is the basic of polynucleotide chain of DNA and each nucleotide is composed of three components - i) a nitrogenous base, ii) a pentose sugar and iii) a phosphate group. Nitrogen base is attached to the pentose sugar by an N-gl...
Therefore, the DNA nucleotide (Fig. 2.1 ) is composed of a 5-carbon sugar (called deoxyribose), a phosphate group, and a nitrogenous base (nitrogen-containing structure). Note the 5′-carbon (at the top) and the 3′-carbon (at the bottom) of the sugar. Fig.2.1 ......
What are the 4 bases of DNA?DNA BasesDNA is made up of nucleotides that contain a phosphate group, a sugar group, and a nitrogen base. DNADNA is the term used to describe the genetic material that is inherited from parent to offspring. The DNA is found in the nucleus of the cell ...
ai:phosphate group pentose sugar(deoxyrbose sugar)+nitrogenous base;ii:four different nitrogenous bases attached to pentose sugar:adenine,guanine,cytosine,thymine;b:two strands of DNA joined by H-bonds between A=T and C=G;[students write in full]at high temperature,molecule has high/increased ...
What is DNA made of? DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and anitrogenbase. The four types of nitrogen bases are adenine (A), thymine (T)...

DNA is a nucleic acid composed of deoxyribose sugar bound to a phosphate group and one of four nitrogenous bases (adenine, guanine, cytosine and thymine). Each section of these three components are referred to as nucleotides, which are joined to the phosphate or sugar of another nucleotide by...
What is phosphate? where does it come from? why is it so important for the human body? and how ICL comes into play.
a. Salt and ethanol were essential in the precipitation DNA isolation process to create a counter ion force great enough to attract the negatively charged phosphate ions of the DNA backbone [3]. Thus, allowing the DNA to be selectively bonded with the positively charged ions of the added ethan...
- Pentose Sugar: This is a five-carbon sugar that forms part of the backbone of the DNA. - Phosphate Group: This group also forms part of the backbone and is hydrophilic (water-attracting). - Nitrogenous Bases: These are the building blocks of genetic information and include adenine (A),...
