DNA & the Genome Flashcards

All 6 cards in this deck

What is DNA and where is it found in a cell?: The chemical that genetic material is made of — two strands coiled into a double helix, found in the nucleus in structures called chromosomes.
Why is DNA described as a polymer?: It is a long molecule made from many nucleotides (repeating units) joined together.
What is a gene?: A small section of DNA on a chromosome that codes for a particular sequence of amino acids, to make a specific protein.
What is the genome of an organism?: The entire genetic material of that organism.
Give two reasons why understanding the human genome is important.: It helps scientists search for genes linked to disease and understand and treat inherited disorders; it can also be used to trace human migration patterns.
True or false? The genome of an organism includes the non-coding DNA as well as the genes.: True. The genome is the entire genetic material of the organism.
