"Scientists will often grow bacteria in prepared petri dishes. In some experiments, the petri dish will also contain paper disks

soaked in a particular antibiotic. The area where the bacteria do not grow is called the zone of inhibition, or ZOI. The diameter of the ZOI indicates the effectiveness of the antibiotic.
The ZOI data collected by one scientist while trying to determine which disk (A, B, C, or D) is most effective at killing Streptococcus bacteria are: Disk D–9 mm, Disk B–8 mm, Disk C–0 mm.

Insert the appropriate heading (with units) for the second column in the data table below and record the data from this investigation"

A--------------13 ( +/- 2 mm) 

B--------------8

C-------------0

D-------------9

Which of the following types of DNA damage cannot be repaired by base excision repair?
Elodia [21]

Answer:

c. Thymine dimer

Explanation:

Thymine dimer

Thymine dimer ( also called the DNA damage ) that is repaired by the nucleotide excision repair which involves the breakage of the phosphodiester bond on the side of the damage , and results in the excision of an oligolnueotide of 10-12 nucleotides in length .

But the base excision repair involves the removal of the damaged base , removal of short polynuceotide and resynthesis of this area with DNA polymerase .

Deoxyribonucleotides, which are DNA precursors, are derived from ribonucleotides. Ribonucleotide reductase catalyzes the convers
Leni [432]

The given question incomplete. However, the missing part is given below:

1.Which of the following are substrates of the ribonucleotide reductase reaction? 2.Which of the following are products of the ribonucleotide reductase reaction? 3.What is the best description of the reaction? 4. what is the ultimate electron donor? 5.Which of the following can directly donate an electron to ribonucleotide reductase?

Answer:

The correct answer is-

1. NDP (ADP, CDP, GDP, or TDP)

2. dNDP ( dADP. dCDP, dGDP, or dTDP)

3. Oxidation-reduction

4. NADPH

5. Thioredoxin

Explanation:

Ribonucleotide reductase reaction is catalyzed by the enzyme called ribonucleotide reductase which is a key enzyme that synthesizeS the deoxyribonucleotide from ribonucleotide, Deoxyribonucleotide is the precursor of DNA.

This reaction is an oxidation-reduction reaction that reduces all ribonucleotides ADP, CDP, GDP, or TDP to dADP. dCDP, dGDP, or dTDP. The ultimate electron donor in this oxidative-reductive reaction is NADPH however thioredoxin directly transfers an electron to ribonucleotide.
