The radical in this question is OH.
The reason this will be a radical, is that the definition of a radical is the presence of an unpaired electron. This causes the radical to be unstable, desperately wanting to do something with the free electron that it has.
Oxygen has a charge of 2-, and Hydrogen has a charge of +1. When you pair them, you end up with a net charge of 1-, which is the presence of that unpaired electron. It will usually be written as: 
Answer: kinetochore
Spindle
fibers are aggregates of micro-tubules that move chromosomes during cell division. They attach to the kinetochore, a structure on chromatids, that when it's pulled separated sister chromatids. The kinetochore is a specialized protein complex found in the centromere of the chromosome.
The answer is true.
<span>Antigens are molecules capable to induce an immune response, "targeted" by antibodies. Antigens are usually proteins, peptides, or polysaccharides but they can combine with lipids and nucleic acids and form more complex antigens (lipopolysaccharide). Usually, antigens are exogenous (foreign substances), but sometimes are part of the host itself (in an autoimmune disease). All of them contain an epitope which is a part of an antigen that can be recognized and bound by an antibody.</span>
Operons are the functional units of transcription and genetic regulation. These are found in bacteria and their viruses where genes coding for functionally related proteins are grouped along the DNA.
The two types of operons are- inducible and repressible.
They regulate the genes as in negative inducible operons, a regulatory repressor protein is bound to the operator. It prevents the transcription of the genes on the operon. If positive inducer is present, it binds to the repressor and changes its conformation so it is unable to bind to the operator.

See the answer below
Explanation:
The question that can be answered with the F2 cross would be <u>if the yellow flower color is dominant over the red flower color in the species</u>. In other words, <u>whether the inheritance of flower color follows a simple Mendelian inheritance or otherwise can be answered.</u>
<em>Assuming that the inheritance of the flower color follows the Mendelian pattern, the red flower trait would re-emerge among the F2 offspring and the ratio of yellow to red flower offspring would approximately be equal to</em><em> 3:1.</em><em> Otherwise, a more complex pattern of inheritance would be involved.</em>
