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.

DNA is a long molecule consisting of Deoxyribose, Phosphate, and a nitrogenous base. One of each of these components bonded together correctly forms a nucleotide. The bases form weak bonds between the two strands, which holds the whole structure together. His Nobel Prize partner, Francis Crick, was playing tennis at the time. With your knowledge of base pairing, correctly work out the complementary strand for the given DNA molecules:. Free nucleotides rush in and bond with their opposite bases, creating a new complementary DNA strand. This process is technically known as semiconservative replication, explain why. Ok, so you know that DNA stays in the nucleus and stored messages well how does its message get sent to the rest of the cell? The answer is RNA. It is made with ribose, not deoxyribose. It tends to form single strands, not double. It has no Thymine T instead it has Uracil U. It is less durable than DNA. Extension: In the space below draw your own DNA strand.

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.
