This describes a gene. Genes, inherited from both parents, dictate everything about a person's physical traits.
These segments are called genes, of course.
Double Helix
Yes and No. Chromosomes are made of DNA wound around proteins. Genes are segments of the DNA that code for traits.
Segments of an individual's DNA, called genes, code for functional products (proteins). These, in addition to the environment, determine the traits of an organism.
What most people think about as genes produce proteins. Scientists now know that some of the genetic code produces segments of RNA that regulate the protein-producing genes.
An operon is a series of genes that code for specific products and the regulatory elements that control operator DNA segments.
Double Helix
Yes and No. Chromosomes are made of DNA wound around proteins. Genes are segments of the DNA that code for traits.
A Gene
There are many kinds of genes that do not code for proteins, most of them code for several distinct types of functional RNAs. For example: ribosomal RNA (rRNA), transfer RNA (tRNA), guide RNA (gRNA), small nucleolar RNA (snoRNA), micro RNA (miRNA) and many others.
