Answer;

a segment of chromosomal DNA

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.

It 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.

Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.

Diferença entre soluções líquidas e líquidos puros
vladimir1956 [14]

Portuguese version:

Não falo português mas:

Uma solução é formada quando algo é adicionado ou dissolvido em um líquido. Você faz uma solução quando adiciona sal ou açúcar a um copo de água. ... Desde que um líquido seja feito de uma única substância, ele permanece puro e é chamado de líquido. Quando algo é adicionado a ele, ele se torna uma solução.

English version: I don't speak Portuguese but:

A solution is formed when something is added or dissolved in a liquid. You make a solution when you add salt or sugar to a glass of water. ... As long as a liquid is made of a single substance, it remains pure and is called a liquid. When something is added to it, it becomes a solution.

Spanish version: No hablo portugues pero:

Se forma una solución cuando algo se agrega o se disuelve en un líquido. Usted hace una solución cuando agrega sal o azúcar a un vaso de agua. ... Mientras un líquido esté hecho de una sola sustancia, permanece puro y se llama líquido. Cuando se le agrega algo, se convierte en una solución.

fReNcH vErSiOn: Je ne parle pas portugais mais:

Une solution se forme lorsque quelque chose est ajouté ou dissous dans un liquide. Vous faites une solution lorsque vous ajoutez du sel ou du sucre à un verre d'eau. ... Tant qu'un liquide est constitué d'une seule substance, il reste pur et s'appelle un liquide. Quand quelque chose y est ajouté, cela devient une solution.

Ok, terminei, tchau.

Okay, I'm done, Bye.

Bien, he terminado, adiós.

D'accord, j'ai fini, au revoir.
