What the concept of genetics and heredity?
It's the science that studies genes. From their discoveries, biotechnology, genetic engineering, cloning, transgenic products, the therapeutic use of stem cells, etc. were developed.
a part of biology that studies mainly occurs as the transmission characteristics of an organism to its descendants. Thus, we can say, briefly, that it is a science that turns to the study of heredity also worrying themselves with the analysis of genes.
It is the biological system of transmission of certain characteristics of living beings between generations. For the full functioning of this structure is needed, genes - piece of DNA (deoxyribonucleic acid) which houses the genetic information.

How is genetic information transmitted?
The information transmitted only by the father
The information is transmitted only by the mother
Genetic information is transmitted through genes, pieces of information contained in the DNA of individuals in the form of separately verified nucleotide sequences. There are two types of heredity: specific and individual.

How are classified the genes?
They can be classified in two ways: dominant and recessive. The dominants are those who impose their characteristics, that is, they are those who determine the characteristics of a species. It is represented by the capital letter which can be found as (AA or BB).
It can be classified in a way by recessives. They are classified by the letters aa and BB
It can be classified in one way by the dominants. Are classified by the letters Aa and bb
4
Which genes are dominant?
The dominant term is related to the genetic transmission of the trait and is represented, in biology, by a capital letter (A, B or V).
The dominant genes of a pure homozygous individual are represented by capital letters, such as AA, BB, VV. In genetic studies, the dominant genes of a hybrid heterozygous individual are identified through the representation of an uppercase and a lowercase letter, such as Aa, Bb, Vv.
5
What is a recessive gene?
Gene in which the genetic trait is not expressed, in the heterozygous state (two different alleles of the same gene); it only expresses its feature when your allele appears in this two pairs of homologous chromosomes (two identical alleles) and when the dominant gene is absent
It is the one that determines a characteristic, even when in a simple dose in the genotype, as is the case with heterozygotes.
6
What are the characteristics that are transmitted through the DNA?
it is a nucleic acid that is related to heredity, as it presents genetic information about each individual and guarantees its transmission. DNA (deoxyribonucleic acid) is an essential nucleic acid for transmitting our characteristics to our descendants.
It is in the DNA that all the characteristics of a living being are encoded, which are unique to each individual. In the case of DNA, pentose is of the deoxyribose type and the nitrogenous bases are adenine, cytosine, guanine and thymine. The set formed by pentose, phosphoric acid and nitrogen base forms the nucleotide
7
Where is the cell's DNA found?
DNA is located in the cell nucleus, therefore, it is in the nucleus that all genetic information is contained. Inside the nucleus it is possible to find bodies, nucleoli, protein compounds, DNA, RNA and nuclear genes, also called genetic code.
in the process of reproduction of living beings. In this way, the main function of DNA is to carry information contained in its sequences, called genes.
8
What does the acronym DNA mean?
masculine noun [Biochemistry] Acronym for deoxyribonucleic acid; nucleic acid that is full of phosphorus and deoxyribose; DNA.
Eukaryotic cells are those that have a nucleus delimited by a nuclear envelope.
9
What is the function of the RNA for the human body?
RNA is an extremely important molecule for living beings and it has the following functions
RNA, unlike DNA, is composed of only one strand and it is produced in the cell nucleus from one of the strands of a DNA molecule. Once ready, the RNA goes to the cell cytoplasm, where it will perform its main function, which is to control protein synthesis.
10
What is the meaning of RNA?
RNA stands for ribonucleic acid and, like DNA, RNA nucleotides contain three components: A nitrogenous base
(deoxyribonucleic acid)
