Answer 1

1. A group of  students analyzed four biological samples that each contain  a different macromolecule.

Here the data is given in the table, based on that we can say that sample 3 is most likely to contain RNA.

• Each macromolecule has a different structure and composition other than C, H and O being common.
• RNA and DNA both are nucleic acid - a  macromolecule that is composed of a pentose sugar, phosphate group and nitrogen base(purine and pyrimidines).
• That can be seen in table number 3- C, H, O, N, sugar, phosphate chain.

2.The transmission of genetic material from one generation to next is necessary for the survival of species.

• one property that ensures  a reliable transmission of genetic information is complementary base pairing.
• That is a pyrimidine base will only pair with the correct purine base and the then only the DNA replication occurs efficiently.
• This leads to transmission of genetic information.
