morpeh [17]

When a person watches television for a long stretch of time in order to observe and then, record the total aggressive incidents occurring during that period is a good example of the rate measure of the behavior. The rate measure refers to the measure of the frequency of the concerned events occurring in the defined period of time. Since, the person is looking for the aggressive behavior on television during his four hour watching, this is a rate measure.

which statement describes only one way that RNA differs from DNA? a. one is a protein, and the other is a nucleic acid. b. they

zalisa [80]

DNA stands for Deoxyribonucleic acid which means it is a nucleic acid. RNA stands for Ribonucleicacid. RNA produces proteins

DNA replicates and stores genetic information.

RNA converts the genetic information contained within DNA to a format used to build proteins.

I would have to say the answer is A based off the information above.

Please correct me if I'm wrong.

vivado [14]

I have attached lac operon model having 4 genes. See attachment for better understanding.

Answer:

The Lac operon is controlled by two signals.

Initiation

Glucose and lactose concentrations control the initiation of transcription of the Lac operon through their effects on the Lac repressor protein and Cap.

Lactose absent (Repression)

When lactose is absent, the Lac repressor binds the Lac operator and shuts off expression of the operon.

Lactose present (Transcription)

Addition of lactose increases the intracellular concentration of a related compound, allolactose. allolactose binds to the Lac repressor, causing it to undergo a conformational change that releases its grip on the operator DNa.

Glucose absent (Repression)

When glucose is absent, cyclic aMp (red triangle) is produced by the cell and Cap binds to DNA.

Glucose present (Transcription)

LacZ, the first gene of the operon, encodes the enzyme b-galactosidase, which breaks down lactose to galactose and glucose.
