Rebecca Roberts is a science writer and communicator. She earned her PhD in molecular biology from the University of the Sunshine Coast in Australia and completed a two-year postdoctoral fellowship at ...

When it comes to identification with DNA, forensic scientists have two basic approaches at their disposal. One approach analyzes nuclear DNA and is useful in identifying someone who is alive or ...

Within the genome, specific segments of DNA called genes act as instructions to make molecules called proteins. Genes are considered the basic units of heredity, as they are passed from parents to ...

DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information ...

Many people follow the golden rules of avoiding direct sunlight between the hours of noon and 3 p.m., staying in […] ...

So how does protein synthesis make hair? If you've looked at the activity (or even the text version of the activity), you know how a section of DNA instructs a cell how to make a protein.

A gene is a fundamental unit of heredity, consisting of a specific sequence of DNA that encodes the instructions for making a particular protein or set of proteins. Genes are passed down from parents ...

DNA can be cut up and separated, which can form a 'bar code' that is different from one person to the next. The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a ...

Histones are a family of basic proteins that associate with DNA in the nucleus and help condense it into chromatin. Nuclear DNA does not appear in free linear strands; it is highly condensed and ...
