Genes are segments of DNA that code for a particular trait. DNA is wound up around proteins into recognizable chromosomes. Chromosomes are located within the nucleus of the cell.
Genes and DNA Genes are masses of DNA that direct certain things - think of genes as orders in the military and DNA as the words in those orders. Genes are smaller than DNA
A chromosome is a long packaged DNA sequence. The human diploid (DNA From both mother and father) cell has 46 of these. A chromosome contains thousands of genes which are the sequences in the actual DNA that code for end products such as proteins.
Genes are relatively small sections of DNA which encode (provide a template for) proteins. Chromosomes are molecules that consist of very long strand of DNA coiled many times, & a few proteins called histones which hold the whole structure together.
chromosomes are made of DNA and proteins. Genes are stretches of DNA that contain code to make proteins. DNA is a molecule made up of a sequence of nucleotides.
