What can be confusing about DNA replication?
Students sometimes confuse DNA replication with cell division. Replication does occur before cell division, but replication only concerns the DNA. Students often have very vague ideas about where genes are located and what they do. Genes are segments of information on DNA strands which code for particular proteins.
How much information is in our DNA?
It is estimated that 1 gram of DNA can hold up to ~215 petabytes (1 petabyte = 1 million gigabytes) of information, although this number fluctuates as different research teams break new grounds in testing the upper storage limit of DNA.
What can DNA tell us about a person?
Examination of DNA variations can provide clues about where a person’s ancestors might have come from and about relationships between families. Certain patterns of genetic variation are often shared among people of particular backgrounds.
How does DNA affect your personality?

DNA consists of a code language comprising four letters which make up what are known as codons, or words, each three letters long. Interpreting the language of the genetic code was the work of Marshall Nirenberg and his colleagues at the National Institutes of Health.
Is DNA a blueprint?
DNA is called the blueprint of life because it contains the instructions needed for an organism to grow, develop, survive and reproduce. Blueprints direct the construction of Buildings, DNA directs the ” construction” of cells and organisms.
