dividing culture of E. coli bacteria to which radioactive thymine had been added.A. One of the daughter cells, but not the other, would have radioactive DNA.B. Neither of the two daughter cells would be radioactive.C. All four bases of the DNA would be radioactive.D. Radioactive thymine would pair with nonradioactive guanine.E. DNA in both daughter cells would be radioactive.

Answer:

The correct answer is option E. "DNA in both daughter cells would be radioactive".

Explanation:

Radioactive thymidine incorporation has irremediable effects in thymine and cytosine in bacteria such as E. coli. Although there are some reports of recovery of E. coli from UV-irradiation DNA damage, the presence of radioactive bases such as thymine is often irremediable. Therefore, after a dividing culture of E. coli exposed to radioactive thymine divides, DNA in both daughter cells would be radioactive.

emmasim [6.3K]

Answer:

Imagine that you are a doctor in maternity ward. During your last shift, 20 babies were born. 10 had blue eyes, and 10 had brown eyes. Remember genotypes are the two alleles given for each trait written with a letter . For this activity 8 - brown eyes b=blue eyes. Phenotypes are the physical appearance of the trait. Given the phenotypes, what are the possible genotypes for these babies? The possible genotypes of these babies are Bb, Bb, bb, bb

Explanation:

Bb= Brown eyes babies

bb= blue eyes babies

from the above analogy, it is crystal clear that the babies are of equal genotypic number which reflects 10:10

Streptomycin is an effective antibiotic because _____________.
Slav-nsk [51]

Answer: Option C.

Both

Explanation:

Streptomycin is an antibiotics produced from bacteria and fungi and it is used to treat bacteria infections (prokaryotic ) such as tuberculosis, mycobacterium infection e.t.c.

It's inhibit protein function in prokaryotes because it's affects the function and performance of 70 s RIBOSOMES which is an organelles for protein production.

Streptomycin does not affect eukaryotes because it does not bind to the RIBOSOMES of eukaryotic cells which in turn does not affect protein production.

Describe at least two biological systems. Explain how the systems are independent from an interconnected with each other.
S_A_V [24]

The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe. The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
