Anyone manage to answer this question?A scientist produced transgenic zebrafish. She obtained a gene from silverside fish. The gene codes for a growth hormone (GH) She inserted copies of this GH gene into plasmids. She then microinjected these recombinant plasmids into fertilised egg cells of zebrafish. 0.9.1 Describe how enzymes could be used to insert the GH gene into a piasmid. [2 marks] Microinjection of DNA into fertilised egg cells is a frequent method of producing transgenic fish. However, the insertion of the transferred gene into nuclear DNA may be delayed. Consequently, the offspring of transgenic fish may not possess the desired characteristic Suggest and explain how delayed insertion of the GH gene could produce offspring of transgenic fish without the desired characteristic [2 marks] The scientist investigated whether the transferred GH gene increased the growth of transgenic zebrafish. She microinjected 2000 fertilised egg cells with the GH plasmid and left 2000 fertilised egg cells untreated. After 12 months, she determined the mean mass of the transgenic and non-transgenic fish. The results the scientist obtained are shown in Table 3. Table 3 A value of 22 * SD from the mean includes over 95% of the data. Type of zebrafish Mean mass of zebrafish / g (2 SD) Transgenic 1.79 ( 0.37) Non-transgenic 0.68 ( 0.13) 019.3 Using Table 3, what can you conclude about the effectiveness of the GH gene on the growth of zebrafish? [2 marks] 019. Explain how two features of the design of this investigation helped to ensure the validity of any conclusions obtained. Do not include calculating the mean or SD in your answer.
