How does DNA determine the organism’s phenotype?

What is the relationship between DNA and phenotype?

Exact DNA sequence of an individual is its genotype. The collection of all observable and measurable traits of that individual is phenotype. If every position and every function of every cell in our bodies was genetically determined, we would need trillions of genes to specify all that information.

How does DNA help to determine an organism’s traits?

DNA contains the information to make proteins, which carry out all the functions and characteristics of living organisms. DNA carries all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein.

Does information in DNA completely determines the phenotypes of organisms?

The production of proteins is controlled by the DNA which sends out mRNA to instruct the ribosomes RNA to make the proteins. So ultimately it is the DNA that controls the phenotype indirectly through the RNA and protein production. But proteins are directly responsible for the phenotype.

What is the relationship observed between an organism’s genotype and phenotype?

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.

How does DNA determine an organism’s structure and function?

It is DNA that contains the genetic code that is used to make proteins. In turn, it is the structure of proteins that determines many of the biological functions and physical characteristics of an organism. Genes are segments of DNA. … The order of the nucleotides determines the gene that an individual will have.

How does DNA determine the characteristics of an organism quizlet?

How does DNA determine our traits? DNA carries the instructions for making all proteins, which determine our traits. … On the ribosome mRNA is read by tRNA, which brings in the correct amino acid to make the protein. This protein will determine a trait.

What does your DNA determine?

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. There are different versions of genes for each feature.
