Construction of DNA, RNA, And Protein By Building Models

Introduction
Nucleic acids are made of nucleotides. When these nucleic acids form sequences they create either DNA or RNA. DNA and RNA are composed of a phosphate, a sugar, and a nitrogen base. The main difference in RNA and DNA is that uracil replaces the base of thymine in RNA. Proteins are essential to maintaining cells by creating hormones and enzymes, and defending the cell. The arrangement of DNA and RNA bases dictates what protein is formed. When DNA is separated into a single strand, ribonucleotides attach to one of the strands and form messenger RNA (mRNA), through the process of transcription. When the gene is turned into a protein sequence by transfer RNA (tRNA), it is called translation.

Purpose
The purpose of this lab was to visualise and understand the roles of DNA, RNA, mRNA, and tRNA during protein synthesis while stimulating replication, transcription, and translation through model manipulation.
