Answer:
Addition of enzymes will increase the speed rate of DNA replication.
Helicase:
It is responsible for DNA strands unwinding and unzip the DNA strands from their center.
Primase:
It is responsible for 5' to 3' direction RNA primers synthesis, okazaki fragment's template.
Polymerase 3:
It synthesize the nucleotides from the 5' to 3' direction on leading end.
Polymerase 1:
It synthesize the nucleotide (okazaki fragments) on lagging strand.
Ligase:
It connects all okazaki fragments.
Topoisomerase:
Topoisomerases are used to regulate the super coiling.
Mutualism is when both sides benefit. The hummingbird gets nectar and the flower is benefited because the hummingbird that has been to other flowers carry pollen on its body which spread the flower when it sucks its nectar, therefore pollinating the flower in the process.
Answer:
B. somatic mutations may be passed to daughter cells by mitosis.
Explanation:
<em>In multicellular organisms, </em><em>somatic mutations may be passed to daughter cells by mitosis.</em>
Mitosis has to do with the division of somatic cells as opposed to germ or reproductive cells. Hence, daughter cells from mitosis are exact copies of their parents. If a mutation occur in the somatic cell of a parent, such could be passed to the daughter cell through mitosis.
<em>Somatic mutations cannot be passed via sexual reproduction. Sexual reproduction can only be used to passed germline mutations.</em>
<em>Not all mutations produced phenotypic changes. Some mutations are silent and have no phenotypic implications.</em>
<em>Not all mutations are point mutations.</em>
The correct option is B.
The Earth is tilted at a 23.5° angle.
