    Sexual reproduction is considered to be a better mode of reproduction because it creates a hybrid that has more vigor than the parents. It also leads to variations that enable organisms to adapt to the changing or prevailing environment. Variations are introduced during meiosis in sexual reproduction, which is an important tool for evolution. It adds survival value to particular species.

    Active immunity is nothing but the immunity when a host is exposed to antigens then the body it self releases the antibodies in order to oppose the antigen but in passive immunity some readymade antibodies are given to the host in order to oppose the antigens, such as a host which is bitten from snake is given some readymade antibodies which can oppose the antigen of snake venom this is type of passive immunity but in case of rhinovirus causing the cold or cough the host body itself produces antibodies in order to oppose the particular antigen this is an example of an active immunity

    PCR in our rDNA technology is nothing but including of three steps they are namely denaturation annealing and and extension of the DNA molecule first of all talking about the denaturation which is carried out by by treating the DNA strand at high temperatures usually at 92 degree Celsius after the process of denaturation annealing is common annealing is nothing but hybridization which is induced through 3 dash primer and in the second stand also from 3 dash primer from now with the help of RNA nucleotides enzymes and we'll again heat it at low temperatures of about 50 to 60 degree Celsius then the third process exited is called as extension extension is nothing but making a long stand from 3-1 a primer and in the down stand from the rest RNA primer then heatin it again at Higher temperature of about 72 degrees celsius the enzyme which is an enzyme extracted from the archaebacteria called as thermus aquaticus which is known as taq polymerase III was doing this extension process then we can find the DNA nucleotides which with the help of rDNA technology which was described first by a scientist called as kary B.mullius

    -The process of replication requires enzymes. -The main enzyme is DNA dependent DNA polymerase. -It is especific and works in direction 5' to 3'. -The process require energy and it is from deoxyrebonucleotide triphosphate - act as substrat and provide energy. -The process of replication start from specific region and it is called oigin of replication. -Consequently the replication in one strand (3'-5') is continous while on other (5'-3') it is discontinous. -The discontinous synthesised fragments are latter joined by enzyme DNA ligase. -The enzyme helicase break the hydrogen bond and there is opening between two strands called replicating fork. -Fragments on discontinous strand - Okazaki fragments. -In one strad there is free OH on 3' so replication is continous. -On othr strand there is no free OH so there is primer and there will be synthsis.(enxyme - primerase)
