genes are made up of what?
303553
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.

Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes.

A gene is a small section of DNA on a chromosome, that codes for a particular sequence of amino acids , to make a specific protein . It is the unit of heredity , and may be copied and passed on to the next generation.

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.

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.

Genes are made of a chemical called DNA, which is short for 'deoxyribonucleic acid'. The DNA molecule is a double helix: that is, two long, thin strands twisted around each other like a spiral staircase. The sides are sugar and phosphate molecules.

Except in some viruses, genes are made up of DNA, a complex molecule that codes genetic information for the transmission of inherited traits. Alleles are also genetic sequences, and they too code for the transmission of traits. ... The short answer is that an allele is a variant form of a gene.

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.

DNA tells a cell how to make proteins through the genetic code. Both DNA and proteins are long molecules made from strings of shorter building blocks. While DNA is made of nucleotides, proteins are made of amino acids, a group of 20 different chemicals with names like alanine, arginine, and serine.

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.

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. ... Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people.

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.

They hold the information to build and maintain an organism's cells and pass genetic traits to offspring. A gene consists of a long combination of four different nucleotide bases namely adenine, cytosine, guanine and thymine. All living things depend on genes as they specify all proteins and functional RNA chains.

Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation.

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.

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. The Human Genome Project estimated that humans have between 20,000 and 25,000 genes.

Genes and Chromosomes. 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.
