We all know that DNA has the ability to identify individuals but, because it is inherited, there are also regions of the DNA strand which can relate an individual to his or her family (immediate and extended), tribal group and even an entire population. Molecular Genealogy (宗谱学) can use this unique identification provided by the genetic markers to link people together into family trees. Pedigrees (家谱) based on such genetic markers can mean a breakthrough for family trees where information is incomplete or missing due to adoption, illegitimacy or lack of records. There are many communities and populations which have lost precious records due to tragic events such as the fire in the Irish courts during Civil War in 1921 or American slaves for whom many records were never kept in the first place. The main objective of the Molecu A. DNA is characteristic of a region B. they are beyond doubt of common ancestry C. DNA strand has the ability to identify individuals D. their unique identification can be provided via DNA 查看答案 更多"{{B}}Text 2{{/B}} We al"的相关试题: [单项选择]{{B}}Text 2{{/B}} We all know that DNA has the ability to identify individuals but, because it is inherited, there are also regions of the DNA strand which can relate an individual to his or her family (immediate and extended), tribal group and even an entire population.

Because computers work with binary numbers, first-generation languages, called machine languages, required the writing of long strings of binary numbers to represent such operations as add. subtract, and compare. Later improvements allowed octal, decimal, or hexadecimal representation of binary strings. It is difficult to write error-free programs in machine language many languages have been created to make programming easier and faster. Symbolic, or assembly, languages—second-generation languages—were introduced in the early 1950s. They use simple mnemonics such as "A" for add or "M" for multiply, which are translated into machine language by a computer program called an assembler. An extension of such a language is the macro instruction, a mnemonic (such as "READ") for which the as A. it is used in designing software. B. it is hardware-independent. C. is should be translated into the computer language by software. D. it is designed to solve some specific problem. 查看答案 [单项选择] {{B}}TEXT B{{/B}} We all know that programming language is the system of syntax, grammar, and symbols or words used to give instructions to a computer.

Our present concern is with how easily and to what extent this cycle can be modified. The question is no mere academic one. The ease, for example, with which people earl change from working in the day to working at night is a question of growing importance in industry where automation calls for round-the-clock working of machines, It normally takes from five days to one week for a person to adapt to a reversed routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts are changed every week; a person may work from 12 midnight to 8 a.m. one week, 8 a.m. to 4 p.m. the next, and 4p.m. to 12 midnight the third and so o A. Because few people like to reverse the cycle of sleep and wakefulness. B. Because sleep normally coincides with the hours of darkness. C. Because people are required to work at night in some fields of industry. D. Because shift work in industry requires people to change their sleeping habits. 查看答案 [单项选择] {{B}}TEXT C{{/B}} We know that he was baptized on April 26, 1564, so that somewhere between April 20 and April 23, four hundred years ago, was born an Englishman who possessed what was probably the greatest brain ever encased in a human skull.
