Concept explainers
(a)
Interpretation : Need to identify the base and sugar in the CMP
Concept Introduction : DNA and RNA are composed of few main components;
- Phosphate group
- Ribose and deoxyribose sugar
- Nitrogenous base
The combination of nitrogenous base and sugar molecule is called as nucleoside which further bonded with phosphate group. The bonding of nucleoside with phosphate group makes nucleotide which further polymerises to form DNA and RNA.
(b)
Interpretation : Need to identify the base and sugar in the dAMP nucleotides.
Concept Introduction : DNA and RNA are composed of few main components;
- Phosphate group
- Ribose and deoxyribose sugar
- Nitrogenous base
The combination of nitrogenous base and sugar molecule is called as nucleoside which further bonded with phosphate group. The bonding of nucleoside with phosphate group makes nucleotide which further polymerises to form DNA and RNA.
(c)
Interpretation : Need to identify the base and sugar in the dGNP nucleotides.
Concept Introduction : DNA and RNA are composed of few main components;
- Phosphate group
- Ribose and deoxyribose sugar
- Nitrogenous base
The combination of nitrogenous base and sugar molecule is called as nucleoside which further bonded with phosphate group. The bonding of nucleoside with phosphate group makes nucleotide which further polymerise to form DNA and RNA.
(d)
Interpretation : Need to identify the base and sugar in the UMP nucleotides.
Concept Introduction : DNA and RNA are composed of few main components;
- Phosphate group
- Ribose and deoxyribose sugar

- Show the mechanism steps to obtain the lowerenergy intermediate: *see imagearrow_forwardSoap is made by the previous reaction *see image. The main difference between one soap and another soap isthe length (number of carbons) of the carboxylic acid. However, if a soap irritates your skin, they mostlikely used too much lye.Detergents have the same chemical structure as soaps except for the functional group. Detergentshave sulfate (R-SO4H) and phosphate (R-PO4H2) functional groups. Draw the above carboxylic acidcarbon chain but as the two variants of detergents. *see imagearrow_forwardWhat are the reactions or reagents used? *see imagearrow_forward
