What is genetics kid friendly definition?
Genetics is the study of the way physical traits and characteristics get passed down from one generation to the next. This is also called heredity. Genetics includes the study of genes, which have a special code called DNA that determines what you will look like and whether you are likely to have certain illnesses.
What are some common DNA terms?
The ABCs of DNA: a glossary of genetic terms
- A (Adenine): One of the four DNA bases.
- Amino Acid: The basic unit of a protein, and sometimes called the “building blocks of life”.
- Ancestry: An individual’s family or ethnic descent.
- Base: The most basic unit of DNA.
What are the 5 branches of genetics?
Using the cytogenetic, molecular genetics, phylogenetic, population genetics, and clinical genetic methods, any mutation can be characterized which are involved in the development of the disease. We can study, The inheritance pattern of disease.
What are 5 facts about genetics?
Ten facts from the Human Genome Project
- 1) There are between 30,000 and 40,000 genes in the human genome.
- 2) A human being can be made from a gene count only twice as great as that of a fly or worm.
- 3) We are not fruitflies or worms because some our genes work differently – we have more “control genes.”
How do you explain DNA to a 5 year old?
It is made of chemical substances that are linked together like a chain. Each piece of DNA has two long strands, or chains. The two strands are joined together. They form a shape like a ladder that has been twisted into a spiral.

What are 4 bases of RNA?
An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA. Attached to each sugar is one of four bases: adenine (A), uracil (U), cytosine (C) or guanine (G).
What are 3 facts about genes?
A gene is a small section of DNA? that contains the instructions for a specific molecule, usually a protein?. The purpose of genes? is to store information. Each gene contains the information required to build specific proteins needed in an organism. The human genome? contains 20,687 protein-coding genes.
What is RNA in simple words?
Ribonucleic acid (abbreviated RNA) is a nucleic acid present in all living cells that has structural similarities to DNA. Unlike DNA, however, RNA is most often single-stranded. An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA.
What is gene simple words?
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.
What is another name for an allele?
allele, also called allelomorph, any one of two or more genes that may occur alternatively at a given site (locus) on a chromosome. Alleles may occur in pairs, or there may be multiple alleles affecting the expression (phenotype) of a particular trait.
