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

Match each vocabulary word with its definition. match the items in the left column to the items in the right column. 1 . periodi
Angelina_Jolie [31]

Answer:

Explanation:

1 . periodicity  

   repeating nature of atomic structure

   Periodicity is the repeating nature or trend of an atom on the periodic table. Periodicity can be inform of ionization energy, atomic radius, nuclear charge etc.

2 . shell

     location of an electron

   Electrons are located in shells. It is where electrons are found in an atom and the probability of finding electrons there are high

3 . non-metals

     high ionization energies

    Non-metals have high ionization energies which is the energy required to remove a loosely bonded electron in an atom. Metals have low ionization energies.

4 . noble gases

       least reactive family

  Noble gases are called inert gases. They have complete electronic configuration and this makes them unreactive.

5 . neutral

       charge on a neutron

   Neutrons have no charge on them. They are subatomic particles found in the nucleus alongside the protons

6 . repel

         like charges

   Like charges repel one another

7 . attract

         unlike charges

  Unlike  charges attracts. Positve attracts negative charges.
