Genes are sections of DNA that code for a particular trait. Genes are ?
Burka [1]

Hello! Allow me to help!

Your question: Genes are ?

My answer: In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function

Why is my answer correct? Good question! Allow me to explain: 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. An international research effort called the Human Genome Project, which worked to determine the sequence of the human genome and identify the genes that it contains, estimated that humans have between 20,000 and 25,000 genes.

Every person has two copies of each gene, one inherited from each parent. 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. 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.

Scientists keep track of genes by giving them unique names. Because gene names can be long, genes are also assigned symbols, which are short combinations of letters (and sometimes numbers) that represent an abbreviated version of the gene name. For example, a gene on chromosome 7 that has been associated with cystic fibrosis is called the cystic fibrosis transmembrane conductance regulator; its symbol is CFTR.

Hope this helps! UwU

Concentrated hydrochloric acid is 36% (Weight/Volume) hydrochloric acid and has a density of 1.18 g.cm -3.
Juli2301 [7.4K]

i. The new concentration is 0.116 M

ii. The new concentration is 0.029 M

<h3>What is the concentration of the original hydrochloric acid acid?</h3>

The concentration of the original or stock hydrochloric acid is calculated as follows:

  • Molarity = Percentage concentration * Density * 1000/Molar mass * 100

Molarity of stock HCl = 36 * 1.18* 1000 /36.5 * 100

Molarity of stock HCl = 11.6 mol/dm

i. Using the dilution formula: M₁V₁ = M₂V₂

M₂ = M₁V₁ /V₂

M₂ = 11.6 * 10/1000

M₂ = 0.116 M

The new concentration = 0.116 M

ii. Using M₁V₁ = M₂V₂

M₂ = M₁V₁ /V₂

M₂ = 0.116 * 5/20

M₂ = 0.029 M

The new concentration = 0.029 M

In conclusion, the new concentrations are found using the dilution formula.
