What is a gene simple definition?
(jeen) The basic unit of heredity that occupies a specific location on a chromosome. Each consists of nucleotides arranged in a linear manner. Most genes code for a specific protein or segment of protein leading to a particular characteristic or function.
What is the best definition of a gene?
: a specific sequence of nucleotides in DNA or RNA that is located usually on a chromosome and that is the functional unit of inheritance controlling the transmission and expression of one or more traits by specifying the structure of a particular polypeptide and especially a protein or controlling the function of …
Where is a gene?
Genes are found on tiny spaghetti-like structures called chromosomes (say: KRO-moh-somes). And chromosomes are found inside cells. Your body is made of billions of cells. Cells are the very small units that make up all living things.
What are genes and DNA?
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person’s genes. Genes are contained in chromosomes, which are in the cell nucleus.
What is gene in microbiology?
A gene is a DNA sequence that encodes a protein, rRNA, or tRNA molecule (gene product). The genetic code determines how the nucleotides in mRNA specify the amino acids in a polypeptide.
What is a gene in my own words?
The definition of a gene is a unit on a chromosome that determines a specific trait in an organism, or a male’s name. An example of a gene is a chromosome unit that determines a person’s eye color. An example of a man named Gene is the actor Gene Wilder. Genes undergo mutation when their DNA sequences change.
What is a gene and how does it work?
A gene is a short section of DNA. Your genes contain instructions that tell your cells to make molecules called proteins. Proteins perform various functions in your body to keep you healthy. Each gene carries instructions that determine your features, such as eye colour, hair colour and height.
What is a gene pool and why is it important?
Importance of preserving Gene Pool: Gene pool represents the total number of genes found within a population , those populations with larger gene pools tend to have more genes, and hence, more genetic diversity . Each gene has a specific purpose, such as giving the plant/animal a particular characteristic, resistance to a disease,…
What are the different versions of genes?
Different versions of a gene are called alleles. Alleles are described as either dominant or recessive depending on their associated traits. Since human cells carry two copies of each chromosome they have two versions of each gene. These different versions of a gene are called alleles. Alleles can be either dominant or recessive.
What are genes and their functions?
Genes are segments of DNA located on chromosomes that contain the instructions for protein production. Their function is to hold all the information required to make and regulate the expression of all the different proteins in cells. The main function of the genes is the form the organism, which is like the parent organism.
What is one form of a gene called?
Different forms of one gene are called alleles. Alleles of the same gene occupy the same locus of a specific chromosome. A gene can have two or more than two alleles.
