<span>The difference in synthesis of lagging strand compared to synthesis of the leading strand is D) Synthesis of the leading strand does not involve RNA primers and Okazaki fragments. DNA polymerase adds nucleotides at the 3' end toward the 5' end in the direction 3' to 5'. The free end of the lagging strand is 5' so DNA polymerase cannot start from that end. The replication of the lagging strands is discontinuous and it involves RNA primers and Okazaki fragments. Synthesis of the leading strand is under control of DNA polymerase.</span>
Answer:
4.38%
Explanation:
Subtract the accepted value from the experimental value.
Take the absolute value of step 1.
Divide that answer by the accepted value.
Multiply that answer by 100 and add the % symbol to express the answer as a percentage.
The cells show characteristics of tumors.
Tumor cells have the ability to grow and proliferate in absence of adhesion or anchoring. This is particularly helpful during metastasis when a cancer cell travels through the bloodstream to another location.
<span>
A cancerous cell has a number of mutations that regulate cell division. In addition, they exhibit impairment in DNA repair system. Therefore, cancer cell divided fast. Since the DNA repair system is nonfictional, the cells do not pause division to repair the mutation.</span>
Yes, there is growing evidence that cognitive impairment is associated with cigarette smoking.
Answer:
Something studied on the molecular level is the water.
Explanation:
Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.
The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.
With respect to other options:
- <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
- <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>
