D all of the above. A monomer is simply a part of the total thing, being a polymer.
They only looked at one school which is not representative of all students in schools. There could have been an illness going around at this particular school but they have nothing to compare their results to. There should be a control group of students at normal temperatures to compare results of the temperature difference effect also.
Answer:
allows the recombination of genetic information
Explanation:
Crossing over is a process that occurs only in meiotic division in sexually reproducing organisms. It is the process whereby the segments of a gene are exchanged between the non-sister chromatids of homologous chromosomes.
Due to this crossing over process that occurs in prophase I of meiosis, the alleles of a chromosomes are recombined to ensure genetic diversity. Hence, according to this question, crossing over results in additional genetic variation during meiosis because it allows the recombination of genetic information.
Answer:
Initiator proteins.
Explanation:
DNA replication may be defined as the process of formation of daughter DNA strand from the template parental strand. Three main process of DNA replication are initiation, elongation and termination.
The bacterial DNA is fail to replicate in yeast cells because the DNA is not able to show initiation in yeast cells. Initiation process is important to start the DNA replication. The specific proteins and polymerase are required in different organism. There is problem in initiation proteins that fails to initiate DNA replication.
Thus, the answer is initiator proteins.
