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