what is the relationship between chromosomes genes and dna?
5087
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.

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. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.

Genes are composed of DNA arranged on chromosomes. Some genes encode structural or regulatory RNAs. Other genes encode proteins. Replication copies DNA; transcription uses DNA to make complementary RNAs; translation uses mRNAs to make proteins.

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.

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

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. ... A trait is any gene-determined characteristic and is often determined by more than one gene.

Difference between Chromosome and Chromatid. A chromosome is a genetic material that has all the features and characteristics of an organism. ... Now, a chromosome is made up of two strands which are identical to each other and these are called Chromatids.

Chromosome- a chromosome is a coiled thread-like structure that contains the genetic material of organisms. A chromosome is the condensed form of a chromatin, which in turn is made up of the DNA and proteins called Histones. So, Chromosome is said to be composed of the identical sister chromatids.

DNA is the molecule that is the hereditary material in all living cells. Genes are made of DNA, and so is the genome itself. A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA.

The gene has same status in genetics as the atom has in chemistry. A gene is a segment in DNA that transfers to the offspring and carries some characteristics of parent to transfer into offspring.

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 are encoded by DNA and found within chromosomes. (Chromosomes are composed of DNA and protein, and DNA is composed of genes and noncoding regions.)

What is a chromosome? Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).

Chromatin is the DNA and proteins that make up chromosomes. Chromosomes are the separate 'pieces' of DNA in a cell (made up of chromatin). Sister chromatids are identical pieces of DNA held together by a centromere and pulled apart during cell division to make new identical chromosomes in the newly made cells.

A chromosome contains many genes. A gene is a segment of DNA that provides the code to construct a protein. The DNA molecule is a long, coiled double helix that resembles a spiral staircase.

Chromosomes are bundles of tightly coiled DNA located within the nucleus of almost every cell in our body. Humans have 23 pairs of chromosomes. Illustration showing how DNA is packaged into a chromosome. ... The chromatin loops are then wrapped around each other to make a full chromosome.

DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.
