Protein chain of amino acids Ribosome moves along 3 The mRNA strand attaches to a ribosome, mucusat articular passes along the strand. Within the ribosome, individual tRNS transfer ribonucleic acid molecules, each carrying an amino acid, slot onto the mRNA. For example, roughly half of the genes found in humans are also found in bananas.

However, it would not be possible to substitute the banana version of a gene for a human one because variations in the order of the base pairs within each gene also distinguish us.

Humans all mucusat articular more or less the same genes, but many of the differences between individuals can be explained by subtle variations within each gene. The extent of these variations is smaller than between humans and animals, and smaller still than the differences between humans and plants. In humans, DNA differs by only around 0. When chromosomes are stained, differences in these regions show up as light and dark bands, giving chromosomes a striped appearance.

The human genome is stored on 23 pairs of chromosomes—46 in total. Of these, 22 pairs store general genetic information and are called autosomes, while the remaining pair determines whether you are male or female.

There are two types of sex chromosome: X and Y. Men have one X and one Y, while women have two X chromosomes. Here, two children are shown to share bands with each parent, proving they are related.

This so-called junk DNA accounts for vast tracts of our genetic material, and we still have little understanding of what it does. However, that does not make it useless. Forensic scientists look at variations mucusat articular noncoding DNA to match criminal mucusat articular to crime scenes. To do this, they analyze short, repeating sequences of DNA within noncoding regions, called short-tandem-repeats STRs. The precise number of repeats is highly variable between individuals.

These are the bandings on chromosome 7. Here, a mutation in the CFTR gene, which makes a protein found in mucus, sweat, and digestive juices, results in the accumulation of thick mucus in the lungs, leaving carriers of the defective gene more susceptible to lung infections. For example, mutations in mucusat articular gene called BRCA1 can predict if a woman is at high risk of developing one form of breast cancer.

And genes are only part of the equation. In the case of personality or lifespan, multiple genes interact with environmental factors, such as upbringing and diet, to shape who we are and who we will become see p. Finding safe ways of delivering replacement genes to the correct cells in humans could lead to cures for many types of inherited diseases—so-called gene therapy.

Inherited traits Mucusat articular possess two copies of each gene, but not all genes are equal. Dominant genes show their effect even if there is only one in a pair, while recessive genes need two copies see p.

Free-hanging earlobes are caused by the dominant form of a gene, while attached earlobes are recessive. That is how many cells exist in the average human body—and we replace millions of these cells every single day.

Cells are extremely small, typically only about 0.

They are also immensely versatile: some can form sheets like those in your skin or mucusat articular your mouth, while others can store or generate energy, such as fat and muscle cells.

Despite their amazing diversity, there are certain features that all cells have in common, including an outer membrane, a control center called a nucleus, and tiny powerhouses called mitochondria.

Cells also contain other structures for assembling proteins, including ribosomes, the endoplasmic reticulum, and Golgi apparatus. The mitochondria provide the cell with energy. This requires lots of energy, so liver cells are packed with mitochondria orange.

Cells use a variety of fuels to generate energy, but the most common one is glucose, which is transformed into adenosine triphosphate ATP. This takes place in structures called mitochondria through a process called cellular respiration: enzymes within the mitochondria react with oxygen and glucose to produce ATP, carbon dioxide, and water.

Mitochondrion While the number of mitochondria varies between different cells, all have the same basic structure: an outer membrane and a highly folded inner membrane, where the production of energy actually takes place. Such materials could include fuel for generating energy, or building blocks essential for protein assembly, such as amino acids.

Some cells can secrete signaling molecules to communicate with neighboring cells or the rest of the body. The cell membrane is largely composed of phospholipids, but it is also studded with proteins that facilitate transport, enable cells to communicate with one another, and identify a cell to other cells.

The membrane is permeable to some molecules, but other molecules need active transport through special channels in the membrane. Cells have three main methods of transport: diffusion, facilitated diffusion, and active transport the last requires energy.

Water and oxygen both cross by diffusion.
