Foods that contains nucleic acids are animal products such as meat, eggs, fish and few plant-based sources are legumes, spinach, mushrooms, yeast and cereals. Adding these foods in the diet will support the body's nucleic acid pool, which is important for cellular function.
Upvote DNA and RNA both are the types of nucleic acids.
DNA (Deoxyribonucleic acid) store the genetic information.
RNA (Ribonucleic acid) helps in protein synthesis. It carry and translates the genetic codes.
Upvote We know that nucleic acids are biomolecules which is responsible for carrying the genetic information in living organisms. Nucleic acids have various properties, including physical, chemical and biological properties.
Physical Properties
Nucleic acids are macromolecular in nature because they ha

What are nucleic acids? Mention their two important functions.
Nucleic acids are biomolecules which is made of nucleotides. They store and transmit the genetic information. Nucleic acids are of two types: DNA (Deoxyribonucleic acid) and RNA (Ribonucleic acid). The following are the functions of nucleic acids.
1. They store and transfer the genetic information.
2.
Upvote The total number of stereoisomers in open-chain aldohexose (such as glucose) is :
The total number of stereoisomers in open-chain aldohexose (such as glucose) is :
The number of chiral carbons in open-chain aldohexose (such as glucose) is four, therefore, the number of stereoisomers = 2? = 16.
Upvote All monosaccharides which differ in configuration at C? and C? gives the same osazone. Since, glucose and fructose differ from each other only in configuration at C? and C? therefore, they give the same osazone. All other options given in the questions do not satisfy this condition and hence, do not
