In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: Cancerous tumors can be divided into primary tumors, which start within the brain, and secondary tumors, which have spread from elsewhere, known as brain metastasis tumors. B: There are two main types of tumors: cancerous (malignant) tumors and benign (non-cancerous) tumors. C: All types of brain tumors may produce symptoms that vary depending on the part of the brain involved. D: A brain tumor occurs when abnormal cells form within the brain.
In each question below is given a statement numbered I, II and III. An assumption is something supposed or taken for granted. You have to consider the following assumption and decide which of the assumption is implicit in the statement. Statement: The June 2018 quarter results of Infosys reflect that the investors waiting for the company to perform as good, if not better, than its largest peer Tata Consultancy Services (TCS) may have to wait a little longer. Infosys, the country’s second-largest software exporter reported slower sequential growth in revenue and profit than TCS for the June quarter (Q1). It also lagged on the fronts of employee attrition and growth in the banking, financial services, and insurance (BFSI) vertical.  Assumptions: I. On the positive side, Infosys continued to add large clients – four in the above $100-million billing category compared with the previous quarter. It continued to retain guidance of 6-8% revenue growth for FY19 while retaining the operating margin band of 22-24%. II. In the near term, the stock performance of TCS is likely to overshadow Infosys given the difference in their growth trajectories. III. The growth momentum of Infosys has slowed relative to TCS. The year-on-year growth in trailing 12-month (TTM) revenue of Infosys in each of the four quarters up to the June 2018 quarter has lagged TCS after leading in the previous five quarters.
Consider the following statements regarding the theory of linkage and choose the correct answer:
1. Genes are arranged in a linear fashion in the chromosomes
2. Genes that show linkage are situated in the chromosome
3. Linked genes remain in their original combination during the course of inheritance
4. The genes which are widely separated show strong linkage, while those closely located, have more chances to get separated by crossing over
Consider the following statements and choose the correct answer:
1. In the phenomenon of linkage and crossing over, the genes are arranged in a linear order in a chromosome
2. The linkage groups in an organism are equivalent to the number of chromosome pairs
3. The chances of crossing over are more between two closely placed genes as compared to the genes placed in far proximity
4. The position of genes is very definite in the chromatid
Tracking the evolutionary history of individual genes in a group of species can reveal which genes have remained in a genome for a long time and which genes have been horizontally transferred between species.
The following sentences form a paragraph. These four parts are numbered as P, Q, R and S. They are not given in their proper order. Read the sentences and choose the alternative that arranges them in correct order. P. The hypothesis was proposed as an explanation for the increased prevalence of type-2 diabetes in certain populations by American geneticist James V. Neel. Q. Thrifty genes refers to a scientific hypothesis which states that obesity in some human beings can be explained by the existence of a ‘thrifty gene’ that aided the storage of excess energy as fat. R. The same genes, however, turned into a biological liability that led to obesity in some people. S. According to the hypothesis, certain genes, by helping in the storage of energy as fat, might have enabled human ancestors live through periods of famine, thus enhancing their chances of survival.
In leguminous plants, both the rhizobium genes and the plant genes influence nodulation and nitrogen fixation. Which one of the following functions is not encoded by the host plant genes?
When comparing pairs of genes or sets of genes in different genomes for this purpose, it is not mandatory for the genes to be orthologs.
Other functional classification schemes for genes include a broader category for genes involved in the same biological process, e.g., a three-group scheme for energy-related, information-related, and communication-related genes has also been used.
Which of the following may lead to tumor or cancerous growth?
