What is the role of a phosphate group in a strand of DNA? 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 grou...
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 ......
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), guanine (G) and cytos...
What is phosphate? where does it come from? why is it so important for the human body? and how ICL comes into play.
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)...
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 the bond between a phosphate group and the ribose sugar group in RNA called?RNA:RNA is a type of nucleic acid in life that is typically single-stranded and transiently made within the cell. There are multiple types of RNA, with the main ones being: ...
Phosphate is an integral part of the molecular backbone of DNA and RNA, constituting the linkage by which the monomeric units are connected. The phosphodiesters in DNA and RNA have distinct stability, owing to the different nature of the sugar units (2′-deoxyribose versus ribose) they connect...
- 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),...
When a nucleoside gains a single phosphate group, it becomes a nucleotide – specifically, anucleotide monophosphate. The nucleotides in DNA and RNA are such nucleotides. Standing alone, however, nucleotides can accommodate up to three phosphate groups, one of which is bound to the sugar portion ...
