If dna is colorless when dissolved in water, how were you able to see the dna after it ran through the gel?.

sergejj [24]

Answer:

To visualise the DNA, the gel is stained with a fluorescent dye that binds to the DNA, and is placed on an ultraviolet transilluminator which will show up the stained DNA as bright bands. Alternatively the dye can be mixed with the gel before it is poured

Which of the following statements is true concerning catabolic pathways?

marysya [2.9K]

The options are incorrect. The correct question with options is:

Which of the following statements is true concerning catabolic pathways?

A. They combine molecules into more energy-rich molecules

B. They supply energy, primarily in the form of ATP, for the cell's work

C. They are endergonic

D. They are spontaneous and do not need enzyme catalysis

E. They build up complex molecules such as protein from simpler compounds

Answer:

B. They supply energy, primarily in the form of ATP, for the cell's work

Explanation:

Catabolic pathways are the metabolic pathways that breakdown the complex molecules into simpler substances. The chemical reactions of catabolic pathways are mostly exergonic with a negative value of free energy change.

The released energy is stored in the form of ATP molecules. The energy-releasing reactions of catabolic pathways supply the cells with ATP molecules to perform the functions. For instance, breakdown of glucose into CO2 and H2O during aerobic cellular respiration is a catabolic process and forms as many as 32 ATP molecules.
