Answer 1

Answer:-

Informational biopolymers can store various kinds of information in their sequence(or polymer chain).To be able to store such information , bio-polymers should be formed from various building blocks. This situation is complementary to the binary system which is used to code all the electronic devices.Various combinations of 1s and 0s form all the required codes in digital systems. Here 1 and 0 are the building blocks. Like that need to be formed from different types of building blocks.

Proteins formed from different amino acids are informational bio-polymers and nucleic acids which are formed from four different types of nucleotides are informational bio polymers.Combinations of various amino acids and nucleotides can store information. For example sequence of three nucleotides contains the information of an amino acid.However if a bio polymer is made up of only one type of structural unit or building blocks, they can not store information.
