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 ...
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 ...
so histones bind with DNA very tightly. The basic repeating structural (and functional) unit of chromatin is the nucleosome, which contains eight histone proteins and about 146 base pairs of DNA ...
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.
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 ...
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 ...
scientists have unlocked the secret interactions between a primordial inorganic polymer of phosphate known as polyphosphate (polyP), and two basic building blocks of life: DNA and the element ...
