The discovery of DNA was one of the most significant findings in the field of science. Today, deeper insight into the DNA structure has unravelled answers to questions that have been around for eons. The Central dogma explains how the DNA codes for the proteins which proceed in three stages, namely, replication, transcription and translation. It is one of the first processes in gene expression. The genetic information flows from DNA to protein and this flow of information takes place in a sequential process of transcription and translation. The RNA transcript carries the information used to encode a protein. Also Read: RNA structure.

Worksheet on dna answer key

The nucleus is a small spherical, dense body in a cell. It is often called the "control center" because it controls all the activities of the cell including cell reproduction, and heredity. How does it do this? Chromosomes, found in the nucleus, are microscopic, threadlike strands composed of the chemical DNA short for deoxyribonucleic acid. In simple terms, DNA controls the production of proteins within the cell. These proteins in turn, form the structural units of cells and control all chemical processes within the cell. Chromosomes are composed of genes. A gene is a segment of DNA that codes for a particular protein, which in turn codes for a trait. Hence you hear it commonly referred to as the gene for baldness or the gene for blue eyes. Meanwhile, DNA is the chemical that genes and chromosomes are made of.
