50 Genetic Ideas You Really Need to Know
Genetics' hottest topics from genetically modified foods to genetic testing are explained in Times science editor Mark Henderson's popular science book.

|
Incomplete Dominance and Codominance
Incomplete dominance and codominance are often confused with one another, but by understanding the basic mechanisms behind these two traits, students can tell them apart.
|
|
Structure and Function of DNA
It is important for biology students who study DNA to understand the function and structure of this important molecule in the cell.
|
|
Understanding Dominant and Recessive Traits
Understanding the differences between a dominant and recessive trait and the functions of alleles is important to knowing how basic genetic inheritance works.

|
Small-scale Genetic DNA Mutation
The result of these genetic mistakes can range from no effect on the organism to the production a defective cellular protein that may have disastrous implications.
|
|
Hereditary and Somatic DNA Mutations
There are two main categories of genetic mutation based on the type of cell they occur in. Changes to a person's DNA can be inherited or acquired after fertilization.
|
|
What Is a Genetic DNA Mutation?
A mutation is a rare change in a gene's DNA sequence that can result in a defective cellular protein. This article covers the basics of genetic mutation.

|
Nucleotides and Nucleic Acids DNA & RNA
This collection of articles explores the components and function of deoxyribonucleic acid (DNA), ribonucleic acid (RNA) and the cellular energy carrier ATP.
|
|
Ploidy: Diplod and Haploid
Humans are diploid organisms with two sets of homologous chromosomes, but we also contain haploid sex cells with one set and half the number.
|
|
DNA: Duplicated and Homologues
Sexual reproducers have 2 sets of homologous chromosomes. Cells must duplicate DNA prior to cell division. What is the distinction between duplicates and homologues?
|
|
Chromosomes & Sister Chromatids
When is DNA considered a chromosome? What is a sister chromatid and how does it differ from a chromosome? The article unravels some of the lingo of DNA.
|
|
Asexual and Sexual Reproduction
Some living things reproduce by cloning; producing offspring that are genetically identical to the parent. Organisms that procreate sexually create genetic novelty.
|
|
What Is Mitotic Cellular Division?
In order for organisms to grow, develop and maintain life, cells must divide. Cellular division involves the basic stages of interphase, nuclear division and cytokinesis.
|
|
Polymerization of DNA & RNA Building Blocks
Prior to cell division, a new copy of DNA must be built. And in order for our cells to make proteins, RNA must be created from the DNA template. How is this accomplished?
|
|
Nucleotides and Nucleic Acids
What kind of molecules are nucleotides and nucleic acids and what are they made of? This article covers the basics.
|
|
Nucleic Acid Function - DNA and RNA
Nucleic acids, such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the vital genetic blueprints, messengers and builders of the cellular world.
|
|
Nucleic Acid DNA & RNA Synthesis
What are deoxyribonucleic and ribonucleic acid made of, and how are these big molecules of genetic information built? This article explains the basics.

|
Pheremones Decide Mice Sexuality
A mouse genetic study in which the TRPC2 gene was eliminated turned males and females into dominant bisexuals.
