Preguntas del test (6)
1If there are 3 billion letters in the reference genome, how much did it cost per letter to sequence the first human genome?
- A$0.10
- B$1.00
- C$10.00
2 When sequencing a genome, how do scientists deal with the problem of how big the genome is?
- AIgnore parts of the genome that are unimportant and only sequence important parts
- BBreak up the genome into smaller pieces and sequence all the pieces at once
- COnly sequence one of the two strands in a double stranded piece of DNA from a genome
3 What is one way that scientists deal with the problem of how small the genome is?
- AUse a microscope to see each letter better
- BAdd enough colored letters to get more than one to stick at a time to the DNA
- CMake copies of the DNA
4Scientists use special colored letters and enzymes to learn what the sequence of a cluster of identical pieces of DNA is. How?
- AA sequential series of pictures of colored spots are taken and analyzed
- BAll the colored letters added into newly made DNA make a unique hue for each spot
- CThe time before the color fades away is an indication of the sequence of letters
5 Once we have the sequences for each piece of DNA from a genome, scientists ________.
- AMake sure all the sequences of every piece are the same and that there are no mutations
- BMake sure there is the same number of letters in each piece
- CPut them all together using the first genome sequence as a guide
6 Next step after DNA has been deciphered will be
- ATo check out if it is correct
- BTo use that knowledge to improve our characteristics
- CTo decipher what the sequence means
