The culture you are working has a doubling time of 2 hours and a cell density of 3 x 10^6 cells per mL. For your experiment, you first dilute the culture 100 fold. Assuming that there is no lab phase and that the cells remain in exponential growth the entire time, what is the cell density (cells/mL) after 10 hours

Answers

The cell density (cells/mL) = 15× 10^6 cells per mL.

Calculation of cell density

The doubling time of culture = 2 hours

The cell density after 2 hours = 3 x 10^6 cells per mL

Since the dilution did not affect the lag phase and exponential growth rate, the cell density after 10 hours is calculated below:

2 hour = 3 x 10^6 cells per mL

10 hours = X

Cross multiply,

[tex]x = \frac{10 \times 3 \times10 {}^{6} }{2} [/tex]

[tex]x = \frac{30 \times 10 {}^{6} }{2} [/tex]

X= 15× 10^6 cells per mL

Therefore, the cell density in (cells/mL) after 10 hours = 15× 10^6 cells per mL.

When dying DNA molecules for DNA laboratory techniques, there are two general types of dyes that specifically bind to DNA to make it fluorescent. One type of dye, such as ethidium bromide, intercalates in between bases inside the DNA, and is only fluorescent when it is intercalated into DNA. Another type of dye rests in the major or minor groove of DNA, such as SYBR Green, and is only fluorescent when it is bound in the groove of DNA. Intercalating dyes are considered to be more carcinogenic than groove-binding DNA dyes if they are absorbed through the skin of the researcher. Which of the following options is the most reasonable explanation for this?Choose one:A. The intercalated dyes will lead to increased mutations upon DNA replication since they are inserted into the bases that are used as a template for DNA replication.B. The intercalated dyes attract more carcinogens in the cell to the DNA than the groove-binding dyes.C. The groove-binding dyes increase the chance of mutation when DNA is being replicated because the sugar phosphate backbone is used as a template during DNA replication.D. The intercalated dyes emit more UV light, causing more damage to the DNA than the groove-binding dyes. Find HCF 2x^5-4x^4-6x and x^5+x^4-3x^3-3x^2 how did labor contribute to industrialization?
