Answer:
Explanation:
Laboratory is a place where ideas and concepts can be tested through experiments. Biology, like any other discipline of science, is based on experimental work and therefore practical forms an integral part of learning.
Magnification by a microscope is a multiple of the X value of the lenses of the eye piece and objective. For example, a 5X eye piece and a 40X objective will magnify the image 5 × 40 = 200 times the size of the object. Similarly, when a 10X eye piece and a 40X objective are used, magnifying power would be 10 × 40 = 400X. Generally, in a compound microscope, the eye piece lenses are 10X or 15X and the objective lenses are 10X as well as 40X.

Answer:
A promoter is a region of DNA where transcription of a gene is initiated. Promoters are a vital component of expression vectors because they control the binding of RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein.

Answer:
B
Explanation:
CRISPR-Cas9 is a gene-editing mechanism that is harnessed from bacteria’s immune system used to cut apart foreign genetic material such as that of bacteriophages. CRISPR-Ca9 has a guide sequence that is used to identify the target sequence. The Cas9 enzyme cuts this target DNA and is replaced with the required piece.
In cancer treatment, the mutated DNA can be replaced, this way, with the wild type.
