What is the relationship between chromosomes DNA and genes?

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 the relationship between DNA a gene and a chromosome quizlet?

DNA contains the instructions, genes, to make proteins that tell what genetic traits the person will have. The DNA along with the proteins make up the chromosomes. The chromosomes are then passed on to the offspring, and with the DNA inside the chromosomes and translation of the genes, its traits are decided.

Which sequence best represents the relationship between DNA?

Answer Expert Verified. The sequence best representing the relationship between DNA and the traits of an organism is: DNA base sequence, amino acid sequence, protein shape, protein function, trait.

What is the relationship among genes DNA 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.

What is the main function of a gene?

Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called proteins.

What are the roles of DNA genes and proteins in each trait?

The traits of a living thing depend on the complex mixture of interacting components inside it. Proteins do much of the chemical work inside cells, so they largely determine what those traits are. But those proteins owe their existence to the DNA (deoxyribonucleic acid), so that is where we must look for the answer.

What are the two main functions of DNA?

Key Concepts and Summary DNA serves two important cellular functions: It is the genetic material passed from parent to offspring and it serves as the information to direct and regulate the construction of the proteins necessary for the cell to perform all of its functions.

How does DNA carry and maintain information?

How does DNA hold information? DNA contains information by maintaining a certain sequence (or group of sequences) of nucleotides. The sequence of nucleotides that makes up the DNA holds codes for putting amino acids in order, or making proteins.

Is sugar a component of DNA?

The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base (Figure 9.3).
