Medical Definition of Gene

You look just like my grandmother! Uncle Michael adds, "And, look, she's getting so tall! Just like her dad.

Only 10 years old, and you look like a basketball player already! Emma's dad emerges from the kitchen to greet the guests.

And you've got such beautiful red, curly hair! In prokaryotes organisms lacking a distinct nucleus, such as bacteria , genes are contained in a single chromosome that is free-floating in the cell cytoplasm. Advances in understanding genes and inheritance continued throughout the 20th century.

As he helps everyone get settled, Emma wonders, "Aunt Rita's grandmother? It runs in the family? What are they talking about? Genes play an important role in determining physical traits — how we look —and lots of other stuff about us. They carry information that makes you who you are and what you look like: Many of these things are passed from one generation to the next in a family by genes.

Each cell in the human body contains about 25, to 35, genes. Genes carry the information that determines your traits say: For example, if both of your parents have green eyes, you might inherit the trait for green eyes from them. Or if your mom has freckles, you might have freckles too because you inherited the trait for freckles.

Genes aren't just found in humans — all animals and plants have genes, too. Where are these important genes? Well, they are so small you can't see them. Genes are found on tiny spaghetti-like structures called chromosomes say: 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 cell is so tiny that you can only see it using a strong microscope. Chromosomes come in matching sets of two or pairs and there are hundreds — sometimes thousands — of genes in just one chromosome. The chromosomes and genes are made of DNA, which is short for deoxyribonucleic say: Most cells have one nucleus say: The nucleus is a small egg-shaped structure inside the cell which acts like the brain of the cell. It tells every part of the cell what to do. But, how does the nucleus know so much?

It contains our chromosomes and genes. As tiny as it is, the nucleus has more information in it than the biggest dictionary you've ever seen. In humans, a cell nucleus contains 46 individual chromosomes or 23 pairs of chromosomes chromosomes come in pairs, remember? Half of these chromosomes come from one parent and half come from the other parent.

Under the microscope, we can see that chromosomes come in different lengths and striping patterns. When they are lined up by size and similar striping pattern, the first twenty two of the pairs these are called autosomes; the final pair of chromosomes are called sex chromosomes, X and Y. The sex chromosomes determine whether you're a boy or a girl: But not every living thing has 46 chromosomes inside of its cells.

For instance, a fruit fly cell only has four chromosomes! Each gene has a special job to do.

The DNA in a gene spells out specific instructions—much like in a cookbook recipe — for making proteins say: PRO-teens in the cell. Proteins are the building blocks for everything in your body. Bones and teeth, hair and earlobes, muscles and blood, are all made up of proteins. When authors co-submit and publish a method article in MethodsX, it appears on ScienceDirect linked to the original research article in this journal. Gene publishes papers that focus on the regulation , expression , function and evolution of genes in all biological contexts, including all prokaryotic and eukaryotic organisms, as well as viruses.

Gene strives to be a very diverse journal and topics in all fields will be considered for publication.

Although not limited to the following, some general topics include:. Gene also welcomes papers that have predominantly a descriptive component but improve the essential basis of knowledge for subsequent functional studies, or provide important confirmation of recently published discoveries. The primary criteria for acceptance are that the work is original and scientifically sound. The journal appreciates that standards of novelty are arbitrary, differ among disciplines and geographic locations, as well as change with time. In partnership with Editors , Referees and Authors, the journal will promote the revision of papers to ensure that accepted papers are reasonably complete and competitive with concurrent submissions in a given field.

This journal has partnered with Heliyon , an open access journal from Elsevier publishing quality peer reviewed research across all disciplines.
