This type of question might be ask for you in your 10+2 Examination.
This type of question may ask to those students at 10+2 level. You might have answer from some of the following steps given below. You can maintains asper your own understanding in equivalence with your markswise.
Genes and Chromosomes
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person’s genes.
Genes contains in chromosomes, which are mainly in the cell nucleus.
A chromosome contains hundreds to thousands of genes.
Every human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes.
A trait is any gene-determined characteristic and is often determined by more than one gene.
Some traits are caused by abnormal genes that are inherited or that are the result of a new mutation.
Genes consist of deoxyribonucleic acid (DNA). DNA contains the code, or blueprint, used to synthesize a protein. Genes vary in size, depending on the sizes of the proteins for which they code. Each DNA molecule is a long double helix that resembles a spiral staircase containing millions of steps. There are four types of blueprint which are given below.
The steps of the staircase consist of pairs of four types of molecules called bases (nucleotides). In each step, the base adenine (A) is paired with the base thymine (T), or the base guanine (G) is paired with the base cytosine (C).
Blueprint Coding Systems.
It never mixed up the code relationship with other code of nucleotides, except they form double or triple coding system. Example AAA-TTT, CC-GG, T-A. This coding system you will study it more in your higher studies in the genetics subjects, like the biotechnology , micro-biology course etc.
It is interesting to know that crime investigation can be detects those accused crime suspected by using this coding method by the scientist expert just by taking the cells from the criminal’s finger print.
Here are some structure of DNA of Chromosomes.
Here DNA is a molecule form a long coiled double helix that resembled a spiral staircase. There are two strands composed of sugar (deoxyribose) and phosphate molecules, are connected by four bases pairs i.e Guanine pair Cytosine and Thymine pair Adenine, bonding with the help of hydrogen molecule. In order to connect with phosphate and sugar which form an amino acid which can form proteins.
