DNA replication is the process of copying a double-stranded DNA molecule. Both strands serve as templates for the reproduction of the opposite strand. The process is sometimes called "semi-conservative replication" because the daughter DNA from the original parent strand contains half of the original and half of the newly synthesized DNA.

Answer;
ATP
ATP is the essential molecule for the detachment.
Explanation;
-Muscles use actin and myosin molecules to convert the energy of ATP into force.
-During the power stroke, the phosphate generated in the previous contraction cycle is released which results in the myosin head pivoting toward the center of the sarcomere, after which the attached ADP and phosphate group are released.
-A new molecule of ATP attaches to the myosin head, causing the cross-bridge to detach.
-The myosin head hydrolyzes ATP to ADP and phosphate, which returns the myosin to the cocked position.
Answer:
RNA is single-stranded and composed of nitrogenous bases, a phosphate group, and pentose sugar.
Explanation:
RNA is different from DNA because instead of having two matching bases; it is only made of one strand of nitrogenous bases. These bases are attached to the phosphate, which holds the whole strand of RNA together. The sugar acts as a carrier for the bases. The sugar in RNA is known as ribose and contains 5 carbon molecules. This is why it is called pentose sugar.
Tumors are caused due to uncontrolled growth of cells. Thus a mitosis inhibitor could be effective medication to treat tumor because it will inhibit cell proliferation and development of tumor.
Explanation:
- Tumors are mass of tissue that developed as a result of uncontrolled cell division.
- Cell division is a continuous process in our body and it replaces old and damaged cells with new one.
- But in case of tumors the cell division takes place in uncontrollable manner and continues to add cells to the tissue while the cell death do not take place.
- Ultimately an unwanted overgrown mass of cell develops that hinders with the normal functioning of the body.
- Tumor are classified as benign tumor and malignant tumors.
- Both these tumors need to be treated as they develop as an unwanted hindrance to the body metabolism.
- The best way to check the growth of tumor is to inhibit the cell division in the tumor tissue.
- Thus a mitotic inhibitor which will inhibit mitosis could be a good medication for treatment of tumors.
The texture of a rock is determined by 3 components of the grain: size, shape and pattern.
The rock in your image (although not very clear in your picture) seems to have very large grains as opposed to several coarse grains. Furthermore, the pattern on the rock is uniformly colored and non-banded.
Thus, from what I can discern in the image, the statements that best describe the rock would be:
The grains in this rock are very large and
The rock has a non-banded pattern.
