what are genes where are they located?

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.

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.

Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene.

Describe the relationship between genes and proteins. Each gene tells the cell how to put together the building blocks for one specific protein. However, the gene (DNA) sits inside a different compartment of the cell (the nucleus) from the location of the cellular machines that make proteins (ribosomes).

Cells are the basic building blocks of all living things, and genes can be found deep within cells. Genes are small sections of DNA that carry genetic information and instructions for making proteins, which help build and maintain the body1.

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.

No, gene is not bigger than DNA… Chromosomes found in the nucleus of the cell that contain dna stretches called as genes. A human cell contains approx. 30,000 genes. Traits which are inherited are determined by one or many genes and single gene can express more than one trait.

Which sentence best describes the relationship between genes and chromosomes? Genes are found within chromosomes. Genes and chromosomes are the only things that form the nucleus. Several chromosomes make up one gene.
150258
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.

What Is a Gene? Genes carry the information that determines your traits (say: trates), which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes.

A gene is a section of a DNA molecule that contains the information to code for one specific protein. How does a DNA molecule determine the structure of a specific protein? The sequence of bases in the DNA molecule determines the sequence of amino acids in a protein.
54363
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.
885811
A gene is a sequence of nucleotides along a DNA strand - with 'start' and 'stop' codons and other regulatory elements - that specifies a sequence of amino acids that are linked together to form a protein.

Answer Expert Verified. Explanation; A gene is a hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.

The chromosome on which the gene can be found. The first number or letter used to describe a gene's location represents the chromosome. Chromosomes 1 through 22 (the autosomes) are designated by their chromosome number. The sex chromosomes are designated by X or Y.

DNA is found in your cell's nucleus, and you get half from each parent. Genes are DNA sequences that contain complex instructions. Just 1 percent of your DNA sequence is genes.

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.
