The working of the given approach for testing the hypothesis in the given experiment. Introduction: A micro ribonucleic acid (miRNA) is a small fragment of RNA, which is derived from the transcription of genes. This fragment of RNA can interfere in the expression of mRNA by binding with its complementary base sequence in an mRNA (messenger RNA). This bond can either lead to the destruction of the mRNA or block translation. A scientist proposes testing the hypothesis that Kitl is significant to coat coloration. To do this, the scientist plans to observe the outcome when an engineered double-stranded microRNA precursor is expressed in mouse embryos. One strand of the precursor would be complementary to Kitl mRNA. In the given experiment, the Kitl gene (mouse equivalent of KITLG gene) and its core promoter were bonded together by genetic engineering. The amount of Kitl mRNA was measured in the skin after its introduction in the embryo of a mouse. The results are shown in the graph provided below.

The Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows: aabb: yellow AABB, AABb, AaBb, and AaBB: red AAbb and Aabb: orange aaBB: yellow aaBb: ? Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why? Question 21 options: orange because A is epistatic to B yellow because A is epistatic to B red because B is epistatic to A orange because B is epistatic to A red because A is epistatic to B yellow because B is epistatic to A

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.
