Explanation:
The first step of DNA replication is the separation of the two DNA strands to create a replication bubble. DNA Helicase is what breaks the hydrogen bonds joining the two strands, allowing it to unravel.
It is a fact that nuclear energy is converted into thermal energy in the core of a nuclear reactor. This is because it is part of a power plant fission act, where nuclear energy heats up water in a nearby vicinity.
This is due to the fact that only homologous chromosomes would have identical genes located at identical sites on those chromosomes. Otherwise, there would be no connection between the alleles of various genes.
Although the genes and loci of the two members of the homologous pair are similar, the alleles may vary.For instance, both allele possess the genes responsible for the attribute of eye colour. While the one has alleles for the blue-eye trait, other has alleles for the brown-eye trait. The homologous chromosomes are said to be heterozygous in this instance since the alleles are different.
On the other hand, when both alleles for a gene that codes for the blue-eye phenotype are present, it is said to be homozygous.
