Heretic about what is nuclei acid nucleus is chemically cross are made of two types of molecules.
2. Nucleic acid
Nuclei acid are further divided into the other two types.
a. Ribonucleic acid RNA
b. Deoxyribonucleic acid DNA
DINAKAR IS THE GENETICS INFORMATION THE FIRST DIRECT EVIDENCE THE DNA IS THE GENETIC INFORMATION COME IN 1943 THROUGH THE WORK OF EVERY AND HIS TEAM IN THIS EXPERIMENT DNA EXITED FROM VIOLENT DISEASES CAUSING STAND UP BACTRIA was added to the culture of the nonviolent bacterium. The nun Vellore and strain were permanently converted virulent bacterium.
this experiment proved that DNA carries genetic information from one generation to another generation.
Chemical combination of DNA
Heavy talk about the chemical composition of DNA how to DNA chemical composition. Dinesh composed by a chemical you not known as nucleotides. Is the nucleotide type consists of three component? These are the following
1. Nitrogenous bases
2. A phosphate group
Structure of DNA:
Watson and Crick proposed AMU did to explain in the structure of DNA. The DNA molecule is composed of to stand the twin around a common axis.
The phosphate chain is located and outer side while the nitrogenous bases project to order center.
Nitrogenous bases to stand one held together by hydrogen bonding.
Adenine always pairs with thymine A-T while genuine pairs with cytosine G-C.
The relationship is known as complementarity that is one strand of DNA is complementary to the other end run in the opposite direction.
The significance of base sequence:
the base sequence of DNA has the following significance.
Dinesh located from different tissue of the same spices has the same base composition.
The best composition of DNA varies from one spice to another.
the best composition of DNA is a given spice remains the same in all circumstances.
Define a number of adenine and thymine an equal number of genuine and Saturn cytokine.
three relationships show that a + b is equal to T+C. This relationship help is determined in between how to genetic information is encoded in DNA in form and past from one generation to other.
Replication of DNA:
Watson and Crick propose the way in which DNA molecules can replicate this process the hydrogen bond holding the to stand RD near together are sequentlyWats broken. this causing The gridiron separation of two heavy up as a per complementary nucleotides join the separated. as a result of identity kal molecule of the double standard, anyone from the reflection process produced The other new DNA molecule.
