A gene is a molecular unit of heredity of a living organism. It is a name given to some stretches of DNA and RNA that code for a type of protein or for an RNA chain that has a function in the organism. Living beings depend on genes, as they specify all proteins and functional RNA chains. Genes hold the information to build and maintain an organism's cells and pass genetic traits to offspring, although some organelles (e.g. mitochondria) are self-replicating and are not coded for by the organism's DNA. All organisms have many genes corresponding to various different biological traits, some of which are immediately visible, such as eye color or number of limbs, and some of which are not, such as blood type or increased risk for specific diseases, or the thousands of basic biochemical processes that comprise life.
A modern working definition of a gene is "a locatable region of genomic sequence, corresponding to a unit of inheritance, which is associated with regulatory regions, transcribed regions, and or other functional sequence regions ".[1][2] Colloquial usage of the term gene (e.g. "good genes", "hair color gene") may actually refer to an allele: a gene is the basic instruction, a sequence of nucleic acids (DNA or, in the case of certain viruses RNA), while an allele is one variant of that gene. Referring to having a gene for a trait, is no longer the scientifically accepted usage. In most cases, all people would have a gene for the trait in question, but certain people will have a specific allele of that gene, which results in the trait variant.
DNA makes genes. A gene is a sequence of DNA that codes for a specific protein or character.
Chromosomes contain genes which are segments of DNA.
Functional segments of DNA are called genes
Genes are the units of heredity, and are made up of segments of DNA
A gene is a portion of DNA. It takes multiple genes to make DNA.
how is the information stored and coded in DNA and genes
genes are in DNA
Chromosomes contain genes which are segments of DNA.
20.3% of your DNA contains genes
No - genes are the parts of DNA that code for a functional product (such as a protein). There are other parts of the DNA which are not genes.
No, DNA is the substance from which genes are made. Genetics is the study of genes and their expression.
Functional segments of DNA are called genes
DNA is the molecule that genes are made of. Chromosomes are the (arbitrary) clumping that genes form in cells.
Genes are the units of heredity, and are made up of segments of DNA
A gene is a portion of DNA. It takes multiple genes to make DNA.
Actually its the other way around. DNA is the structure that contains genes and passes them from generation to generation allowing traits to be inherited. I wish I could go into better detail but I'm more of a physics and chemistry kinda guy.
DNA is in genes, and genes are in chromosomes.
