Two genes, BRCA1, located on chromosome 17q21 (5,6), and BRCA2, located on 13q12-13 (7–9), have been shown to predispose to familial breast cancer.
The correct answer is option B. The scientists were studying if the mud snails can reproduce both sexually and asexually. The characteristics in the study included parameters such as the mating season, number of offspring, effect of environmental stress conditions and lack of mates. Out of all the parameters being studied can affect asexual reproduction in the mud snail but lack or presence of mates is a parameter required to be studied to determine the mode of reproduction i.e. sexual or asexual because need for mates or mate dependent reproduction occurs in case of sexual reproduction.
Answer:
As my study programme is concerned with the field of biotechnology, I hope that by the end of the proposed study programme, I will be able to gain knowledge about the molecular tools and the concepts and trends in genome editing. I shall be able to perform techniques such as PCR, gel electrophoresis, cell culturing easily. I would be able to grasp better knowledge in the fields of plant biotechnology, animal biotechnology, Industrial biotechnology and marine biotechnology.
In this scenario,I guess the answer is roughly around 300 children die every year from the diseases in which the vaccinations are available. Hope this is the correct answer then and would surely be of big help to you then.
