Histones are spools of proteins that surround the chromosome and control the switching on of genes. National Human Genome Research Institute. Changes made to the protein spools that surround chromosomes are passed down generations, proving that inherited traits are decided by more than just DNA, says a new study.
Traits are the physical manifestation of your genes. Brown hair or blue eyes are examples of traits. Genes, are pieces of DNA which code for proteins, which subsequently result in traits. So, if you have a really long piece of DNA, a gene is a part of that DNA. That part gets 'transcribed' to mRNA, which gets 'translated' into protein. The protein is what is responsible for traits. Alleles are 'flavors' of genes. We all have 46 chromosomes (humans). 23 are from the mother and 23 are from the father.
