DNA sequencing of non-human organisms
The genome of Mycoplasma pneumoniae contains 816394 DNA bases.
1) Write the number out. | 816394 |
2) Place a decimal point between the first two non-zero parts of the number. | 8.16394 |
3) Jump right towards the original decimal point counting how many spaces were moved, this number will be the power added to the 10. | = 5 = 105 |
4) Round to three significant figures and construct the number. | 8.16 x 105 |
The genome of Streptococcus pneumoniae contains 2160837 DNA bases.
5) Write the number out. | |
6) Place a decimal point between the first two non-zero parts of the number. |
2.160837 |
7) Jump right towards the original decimal point counting how many spaces were moved, this number will be the power added to the 10. |
2.160837 = 6 = 106 |
8) Round to three significant figures and construct the number. |
2.16 x 106 |
