Answer:
chemical change.
Explanation:
There are two types of changes in matter: physical change and chemical change.
physical change- it is a change in matter that alters only its physical properties or its physical appearance. This type of change is reversible. For example- freezing of water, the water turns into solid ice and it can be reversed by melting the ice.
chemical change- it is a change in matter that alter its chemical and thus its physical properties. Most chemical changes are irreversible. for example- burning of paper, results in black soot and ashes- Thus changing both physical and chemical properties.
Answer:
Nucleic acids are of two types DNA and RNA which are made up of monomeric units called nucleotides.
One monomer is one nucleotide which further consists of three parts:
1: Nitrogenous base
2: Sugar (a ribose sugar in RNA and a deoxyribose sugar in DNA)
3: Phosphate group
Explanation:
If we talk about single strand of nucleic acid DNA or RNA, there is a phosphodiester linkage that holds monomers together in a strand of nucleic acids. This phospho di ester linkage is formed when a condensation reaction occurs between a hydroxyl group of two sugars and a phosphate group.
