what is the relationship between genes and organisms?
443513
A gene is a segment of DNA that can be copied to make RNA. The nucleotide sequence in RNA is translated into the amino acid sequence of a protein. Proteins are the main determinants of the basic structural and physiological properties of an organism. The characteristics of a species are encoded by its genes.

The Relationship Between Genes and Proteins. Most genes contain the information require to make proteins. The journey from gene to protein is one that is complex and controlled within each cell and it consists of two major steps – transcription and translation. Together, these two steps are known as gene expression.

A gene is a piece of DNA that contains the information necessary for the cell to make one protein. ... Genes are located on chromosomes, which are large pieces of DNA contained in a eukaryotic cell's nucleus.

An organism is an individual. A species is a collection of individuals with a very large number of common genes. The concept of species is (among other functions) used to expedite talking about individuals.

Notes: Genes are DNA sequences instruct cells to produce particular proteins, which in turn determine traits. Chromosomes are strings of genes. Mutations are changes in gene's DNA sequence. RNA is somewhat similar to DNA; they both are nucleic acids of nitrogen-containing bases joined by sugar-phosphate backbone.

A gene is a portion of DNA that determines a certain trait. An allele is a specific form of a gene. Genes are responsible for the expression of traits. Alleles are responsible for the variations in which a given trait can be expressed.

A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. ... In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.

Heredity is the passing of Genes from parents to offspring. A Chromosome is the structure that holds the genetic material (DNA). DNA is the genetic material that provides instructions for all the body's functions. A Gene is a section of DNA that provides instructions for specific traits.

The two terms are often used at the same time to describe the same organism, but there is a difference between genotype and phenotype: An organism's genotype is the set of genes in its DNA responsible for a particular trait. An organism's phenotype is the physical expression of those genes.

A gene is a specific section of a chromosome where the base pairs that code for the characteristic are stored whereas an allele is the actual sequence of the base pairs in the section.

Atoms are the smallest particle of matter. Genes are segments of DNA that code for a specific protein responsible for a trait in a living thing. Since genes take up space (have volume) and have mass, they are considered matter. Thus, genes are made of atoms.

The Human Genome Nomenclature Organization defines a gene as “a DNA segment that contributes to phenotype/function”. A gene is a linear section of DNA – of a chromosome – that contributes some function to the organism.

Genes Have Alleles The traits an organism displays are ultimately determined by the genes it inherited from its parents, in other words by its genotype. Animals have two copies of all their chromosomes, one from each parent.

Genes exist on chromosomes, which are large strands of DNA. A gene is always smaller than its host chromosome, but not all chromosomes are the same length. ... That's larger than many bacterial chromosomes.

Gene. A gene is a stretch of DNA or RNA that determines a certain trait. Genes mutate and can take two or more alternative forms; an allele is one of these forms of a gene. ... Chromosomes occur in pairs so organisms have two alleles for each gene — one allele in each chromosome in the pair.

The expression of genes in an organism can be influenced by the environment, including the external world in which the organism is located or develops, as well as the organism's internal world, which includes such factors as its hormones and metabolism.

Each chromosome contains genes for every physiological trait of a living organism in the form of long chains of DNA. Gene is a small stretch of dna we can say small nucleotide sequence, which would code for a particular protein.
