The Human Genome Project

The Human Genome Project is an international scientific research project with the primary aim of determining the sequence of chemical base pairs that make up DNA and identify and map the approximately 20000-25000 genes in the human genome from a physical standpoint and functional. The human genome consists of approximately 30,000 genes. Humans have a similar number of nitrogen bases - about 3 million and about 3,000 megabases - similar to that of other vertebrates such as rats and others are also affected. In addition to protein-coding genes, the human genome contains thousands of RNA genes, whose transcription reproduces transfer RNA (tRNA), ribosomal RNA (rRNA), microRNA (miRNA), or other non-coding RNA genes. The ribosomal RNA and transfer are essential in the formation of ribosomes and translation of proteins.

History:

One of the questions that mankind has been raised since it began to analyze the world, living things and their characteristics is that of why the children resemble their parents?
It all started at around Gregoriom Mendel (1882-1884), founder of genetics, who was an Austrian monk who worked with peas, among others. Playing a controlled several generations of these plants and analyzing some of their characteristics, could deduce the first laws governing biological inheritance with which determined that there are certain ‘factors' responsible for transmitting characters from parent to offspring. Searching of these factors gradually rose, reaching the cell nucleus, in the chromosomes. But the big jump in this knowledge is only slightly more than half a century: in 1953, the American James Watson (19 289 young zoologist, and Francis Crick (1916-2004), physicist, with the help of various specialists in chemical analysis, able to develop a model of the structure of the main molecule that forms the chromosomes: deoxyribonucleic acid or DNA.

This molecule, together with another similar, ribonucleic acid or RNA, are responsible for heredity, the DNA is passed from parents to offspring carrying the information for cells to manufacture its protein, both which are enzymes such as forming part of the structure of cells and tissues.

This discovery is considered the most important, because from that moment began to develop many processes that can modify the structure of living things and characteristics that show.

DNA Extraction Home Experiment

In this experiment, our main interest is to demonstrate the presence of DNA in the bodies. In this opportunity we will be using strawberries as evidence.

OBJECTIVE: The main objective of this experiment is to observe DNA, using only household materials.

-Hypothesis:
- Do fruits have DNA?
- Can we observe it?

Materials:
-Ziploc-Bag
-Strawberries
- Water
- Glass vase
- Spoon
- Soap
- Cold alcohol

Introduction: The deoxyribonucleic acid (DNA) is the molecule carrying the genetic information. It has encoded information about our physical features, capabilities to digest or not a food, as well as some features to have or not certain diseases.
In the experiment we will present, the DNA extraction will be from the strawberries. For this experiment it is necessary to grind the fruit by a mechanical process to first disaggregate the tissue cells and then break some of them, which we will be releasing the DNA.
2. - This will need to purchase some materials and substances and prepare the following solution.


Development/ procedure: First we smash the strawberries and we add a little water. When viewed as a substance, we add a little soap, the beats do not see anything, and everything remains the same.
After we let it stand for a moment (without stirring) we add some alcohol. Why alcohol? Because alcohol dehydrates the DNA.
Minutes later we see as white bubbles begin to form. This is because DNA is soluble in water (and therefore invisible to our eyes, as each molecule is surrounded by water and our eyes do not perceive individual molecules of DNA) but insoluble in alcohol, which originates in the presence of this engages.
After this experience, it is worth noting what happens. And we can see how the DNA was separated into small white ball floating.

Results: In the end, after standing for a moment, we can admire how a species of white bubbles that float through the alcohol are formed, that is the DNA.

Conclusion: After our investigation and experimentation, we can affirm that DNA is present in every DNA extraction body .The experiment requires a series of basic steps that are not very simple or straightforward, but in the end we can clearly observe DNA

Hypothesis:

-What are the components of DNA that influence to differentiate?

-To what degree the chromosomes determine a change in our body?

-How are genes associated with chromosomes?

-How do mutations arise?

-What is needed to make a clone?

Objective:

In This project we will investigate as the structure of DNA, made up of carbon (C), hydrogen (h), oxygen (O), nitrogen (N) and phosphorus (P).How these elements are organized and their effect on our organism. Also we will analyze as is the mechanism by which genes pass from one cell to its descendants during playback. Also we’ll inquire about the important aspects of living things that have to do with genetics.
-Analyze the physical and chemical structure of DNA and its importance in human behavior.
