What is the definition of a gene?

Answer 1

http://en.wikipedia.org/wiki/Gene

Answer 2

the basic physical unit of heredity; a linear sequence of nucleotides along a segment of DNA that provides the coded instructions for synthesis of RNA, which, when translated into protein, leads to the expression of hereditary character.

Answer 3

A hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.

Answer 4

the basic physical unit of heredity; a linear sequence of nucleotides along a segment of DNA that provides the coded instructions for synthesis of RNA, which, when translated into protein, leads to the expression of hereditary character.

I learned it in life science in 7th grade.

but I got this answer from dictionary.com

very useful

Answer 5

a gene is the basic physical unit of heredity; a linear sequence of nucleotides along a segment of DNA that provides the coded instructions for synthesis of RNA, which, when translated into protein, leads to the expression of hereditary character.  

Answer 6

The basic biological unit of heredity. A segment of DNA needed to contribute to a function.

Answer 7

Genes are working subunits of DNA. DNA is a vast chemical information database that carries the complete set of instructions for making all the proteins a cell will ever need. Each gene contains a particular set of instructions, usually coding for a particular protein.

Answer 8

Withing each cell their lies a complex sequence of amino acids and proteins. These chemicals form chains. It might be easier to think of it as a programming language on your computer. Now this language of chemicals spells out all of the different functions of the entire organism, much like all those little programs that run in the background of your computer. A gene is simply one of those little programs. It spells out a certain trait that makes up a larger series of traits that forms the organism as a whole.

Answer 9

a gene is something that contains dna

the dna makes up who you are

that means that genes control who you are, different combinations create different individuals

Answer 10

DNA traveled down through your heritage that has specific or distinguished features as characterized by differences in mankind's idiosyncrasies
