In a signal transduction pathway, fine tuning of the cellular response occurs in several steps. Which of the following best desc

ribes how the response would be affected if the molecular changes that occur during a signaling pathway lasted for a prolonged period?
Inactivation mechanisms would be triggered before the pathway could be completed.
Receptors would be unable to return to their inactive form and respond to new signals.
Scaffolding proteins would cause potentially harmful signal amplification in the cytosol.
Signaling proteins would be unable to take part in multiple pathways, as specificity is lost.

Answer: Receptors would be unable to return to their inactive form and respond to new signals.

Explanation:

Many signaling pathway involves the regulation of the protein synthesis. It involves the turning off or on of some of the specific genes present in the nucleus. If the receptors become unable to resume to the inactive form the may not be able to produce  new signals during protein synthesis. The final activated molecule in a signal pathway may not function as transcription factor.

1. What are Chargaff's rules?
kotegsom [21]

1)Chargaff's rules state that DNA from any cell of any organisms should have a 1:1 ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.

2)DNA structure

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

3)A nucleotide consists of three things: A nitrogenous base, which can be either adenine, guanine, cytosine, or thymine (in the case of RNA, thymine is replaced by uracil). A five-carbon sugar, called deoxyribose because it is lacking an oxygen group on one of its carbons. One or more phosphate groups.

4)DNA replication is said to be semi-conservative because of this process of replication, where the resulting double helix is composed of both an old strand and a new strand. ... Semiconservative replication would produce two copies that each contained one of the original strands and one new strand.

5)The diagram has show in above.

6)complementary base pairing is necessary because the double helix shape would not be the same if not. Doubles would only pair with doubles and the singles to singles.

Which one of the following statements holds true for the induced-fit model?
Andrews [41]
The correct answer is...Once the enzyme binds to the specific substrate molecule, subtle structure changes occur in the active site, which are reverted when the reaction is over.
