Explanation:
This question appears to be incomplete. During blood doping, the athlete will have blood drawn and stored. The athlete will then allow sufficient time for the body to replenish the removed blood. Immediately prior to the event, the athlete will inject the stored blood back into his/her system. Blood doping<span> effectively increases the number of </span>red blood cells<span> in the bloodstream to above normal. This enhances performance because blood cells carry </span>oxygen<span> from the </span>lungs<span> to the </span>muscles<span>, and a higher concentration of oxygen in the blood can improve an athlete’s </span>aerobic capacity<span> a</span><span>nd </span>endurance.
Cell Differentiation and Tissue. Within multicellular organisms<span>, </span>tissues<span> are organized communities of cells that work together to carry out a specific function. The exact role of a tissue in an </span>organism<span> depends on what types of cells it contains !

Answer:
The correct answer will be option-A.
Explanation:
Recombination is a process in which the DNA sequences get exchanged between two homologous chromosomes. It occurs during gamete formation and is the basis of genetic diversity.
The process requires many enzymes, the key enzyme of which is Recobinase A or RecA protein which catalyzes the homologous recombination using ATP as an energy molecule.
RecA binds to the single-stranded DNA at the break site and forms pre-synaptic structure. Thus, it initiates the reaction of strand exchange and is the correct answer.
