Why are nucleic acids important macromolecules?
In point form, nucleic acids...
- store genetic information (i.e. DNA)
- transmit genetic information (i.e. mRNA)
- process genetic information (i.e. ribozymes)
- involved in protein synthesis (i.e. tRNA and rRNA)
Because they contribute to the process of protein synthesis. Without them no proteins can be made in the body, and proteins have many roles without which the body cannot survive.
There are several types of nucleic acids that can be categorized under two major groups which are DNA (deoxyribonucleic acid ) and RNA (ribonucleic acid).
DNA is responsible for carrying the code for the structure of the protein. It is made of sub-units and each three of three of them codes for one amino acid (the building unit of the protein).
The other group of nucleic acids which is RNA molecules is responsible for the process of protein synthesis. There are three types of RNA, they are the mRNA,rRNA, and tRNA. mRNA is responsible for carrying the code from the DNA which is found in the nucleus to the cytoplasm. tRNA is responsible for bringing the proper amino acid to the proper position next to the mRNA so they can be connected in the proper order. rRNA is responsible for building the ribosome which is the site where mRNA is attached to when making a protein.
