Epigenetics:
Is the study of heritable changes in our genes functions that occurs without a change in our DNA sequence. So it refers of modifications to the genome that not involve a change in the nucleotide sequence. Non-genetic factors cause in our genes to behave (or Express themselves”) differently. There are many objections of the use of the term to describe Chemicals modifications ofhistones if this has to be with modifications that are heritable. Epigenetics changes can modify the activation of certain genes, If a gene desactivation occurs in a sperm cell (that results in fertilization), some epigenetics changes can be transfered to the next generations.

-Epigenome: Epigenetic is the interlocutor of the environment of the genetic.
This explains the accion of the life style inour genes.

-Epigenesis: The epigenetics variations can control the activity of the genes. If the concentration of “X” substance is high the activity is going to be the same. The epigenetic code is constituted of a system of molecules bound to the DNA or histones that governs the expresión of genes, lod tails of histone proteíns catalyze a variety of Chemicals additions.

-Epigeneticinheritance: Results of the transmition of sequence in the non-DNA information through meiosis and mitosis. The epigenetic information modulates the expresión of the genes without alter the DNA sequence.

-Imprinting: When we talk about imprinting we refers to genes that can modify their function without a change in DNA sequence.
-Is linked to parental origin.
-An imprinting gene manifest in a mannerwhen the origin is paternal and maternal too , is depending if this comes of a men or a women.

Genetics:
Is the study of inheritance the process when the father transmit certain genes to his sons. The appearance of a person: height, hair color, skin color, eyes color, etc is determinated by genes.

Other characteristics affected by genes are:
-The probability to have certain diseases.-Mental capacities.
-Natural talents.

An abnormal trait that is passed from parents to children can:
-Don’t have effect in health.
-Have minimal impact.
-Have a gramatical effect in human life style quality.

For most of gene disorders, is recommended genetic counseling and is possible that many people want to search prenatal diagnosis.

Human beings have cells with 46 chromosomes - 2 sexchromosomes and 22 pairs of non-sex chromosomes (autosomes). Males are "46, XY" and females "46, XX". Chromosomes are composed of DNA.

Genes are sections of DNA and its location is called locus. Most genes carry information that is necessary to produce a protein.

The pairs of autosomal chromosomes (one from the mother and one from the father) carry basically the same information, that is,each has the same genes, but there may be slight variations in these genes. These slight differences occur in less than 1% of the DNA sequence and producing variants of a particular gene, called alleles.

Happiness:
Is a frame of mind that is produced when someone think that have reached goal.
This state makes you have inner peace, positive environmental approach, while encouraged to conquernew goals. It is defined as an internal condition of satisfaction and joy.

A positive mood, the ability to tackle a task proposed taking it to term. The end result is pleasing to the person who undertakes the task.
In this process may experience emotions derived, which need not be pleasant, being a result of learning before something happened.

There are many factors that have been relatedwith happiness but it doesn’t exist a valid method to prove long-term of the word in a meaningful way for most people.
Happiness is an emotion and like the others it has causes that can be understood or controlled. Happiness is a long lasting enduring enjoyment of life, that can be defined like be in love with life. Its the reward for achieving a good character and personal values in life. Some...
