Based on the bacterial transformation using the plasmid containing the gene for GFP, what phenotype would you expect for cells f

rom a successful transformation spread on agar plates containing LB, ampicillin, and arabinose in the presence of UV light? A white smear or 'lawn' A brown smear or 'lawn' Glowing E. coli colonies White E. coli colonies No colonies / no growth

Answer:

No colonies, no growht.

Explanation:

The statement does not mention that apart from the GFP reporter gene, the plasmid contains ALSO the ampicillin resistance gene. This way, if you spread your traqnsformed cells on LB plates containing ampicillin, they will not be able to grow.

Gregor Mendel is referred to as the father of which classical science?
Elenna [48]
Gregor Mendel was a scientist born in the Austrian Empire in 1822. He conducted pea plant experiments and established many of the rules of heredity. He was explaining the significance of invisible factors ( now called genes ) for the inheritance. He also experimented with hawkweed and honeybees. Mendel is referred to as "The Father of Genetics". Answer: Genetics.

Marta_Voda [28]

Imagine you are surveying a population of a mountain range where the inhabitants live in the valleys with no inhabitants on the large mountains between. If your sample area is the valleys, and you use this to estimate the population across the entire mountain range, <u>you overestimate the actual population size</u>

<u />

Explanation:

  • An estimate that turns out to be incorrect will be an overestimate if the estimate exceeded the actual result, and an underestimate if the estimate fell short of the actual result.
  • The mean of the sampling distribution of a statistic is sometimes referred to as the expected value of the statistic. Therefore the sample mean is an unbiased estimate of μ.
  • Any given sample mean may underestimate or overestimate μ, but there is no systematic tendency for sample means to either under or overestimate μ.
  • Bias is the tendency of a statistic to overestimate or underestimate a parameter. Bias can seep into your results for a slew of reasons including sampling or measurement errors, or unrepresentative samples

sp2606 [1]

Answer:

The correct answer is -

1. c. both

2. b. gluconeogenesis

3. d. neither

4. b. gluconeogenesis

5. a. glycolysis

6. c. both

7. a. glycolysis

8. d. neither

Explanation:

Gluconeogenesis is the formation or synthesis of glucose while glycolysis is the conversion of glucose into pyruvate. Gluconeogenesis requires an enzyme for a non-reversal reaction which is not required in glycolysis.

Glyceraldehyde 3-phosphate dehydrogenase is an enzyme present in glycolysis that converts glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate. It is a reversible reaction, this enzyme also present during gluconeogenesis converts 1,3-bisphosphoglycerate to glyceraldehyde 3-phosphate.

Glucose 6-phosphate to glucose during gluconeogenesis by glucose-6-phosphatase. Alcohol dehydrogenase is used for the conversion of ethanol into acetaldehyde and neither present in glyconeogenesis nor glycolysis. Oxaloacetate converts to phosphoenol pyruvate during gluconeogenesis by Phosphoenol pyruvate carboxykinase.

Fructose 6-phosphate changes into fructose 1,6-bisphosphate by Phosphofructokinase-1 during glycolysis.

Phosphoglycerate mutase is present in both pathways during glycolysis and during gluconeogenesis. This enzyme converts 3-phosphoglycerate to 2-phosphoglycerate and also converts 2-phosphoglycerate to 3-phosphoglycerate in glycolysis and gluconeogenesis respectively.

Hexokinase converts glucose to glucose 6-phosphate during glycolysis. However, Pyruvate dehydrogenase neither present in glycolysis nor gluconeogenesis.
