Answer:

<em>The correct option is C) The helicase enzyme unwind the DNA molecule into two strands.</em>

Explanation:

DNA replication occurs in a semi-conservative manner. This means that each strand of the DNA can give rise to a new strand. For the process of DNA replication to begin, firstly it is necessary that the DNA unwinds. Topoisomerases are enzymes which are known to remove the super-coiling of the DNA. Helicases can be described as the enzymes which separate the two strands of DNA from the region where replication has to begin. Hence, option C is correct.

What do you call the non-Mendelian inheritance pattern that states that both traits are dominant and both appear in the organism
dangina [55]

Answer:A. Codominance

Explanation:

This is a type of genetic inheritance where neither of the genes is dominant over another. Thus both pair of the gene are expressed on the same LOCUS equally with none masking another. Therefore an   individual receive both  allele of a heterozygous  gene, and have equal phenotypic expression

An example is the AB  blood group in man, where both allele present on the same locus are fully expressed with no one dominant over another.

Incomplete dominance refers to a blend of  alleles where one does  not have  full dominance over another another, therefore gives a new phenotypic expression different from both alleles.

e.g  pink flower allele in four o'clock flower.

Which form of natural selection does a graph repeat
Nookie1986 [14]
May i have choices but <span>Natural selection can take many forms. To make talking about this easier, we will consider the distribution of traits across a population in graphical form. In we see the normal bell curve of trait distribution. For example, if we were talking about height as a trait, we would see that without any selection pressure on this trait, the heights of individuals in a population would vary, with most individuals being of an average height and fewer being extremely short or extremely tall. However, when selection pressures act on a trait, this distribution can be altered.</span>
