You are studying a bacterium that utilizes a sugar called athelose. This sugar can be used as an energy source when necessary. M

etabolism of athelose is controlled by the ath operon. The genes of the ath operon code for the enzymes necessary to use athelose as an energy source. You have found the following: The genes of the ath operon are expressed only when the concentration of athelose in the bacterium is high. When glucose is absent, the bacterium needs to metabolize athelose as an energy source as much as possible. The same catabolite activator protein (CAP) involved with the lac operon interacts with the ath operon. Based on this information, how is the ath operon most likely controlled?

Answer:

The ath operon is most likely controlled by the CAP and a repressor similar to the lac operon.        

Explanation:

The CAP senses the low concentration of glucose and activates the transcription of the ath operon for it to metabolize the athelose and obtain energy. When the glucose is in high concentrations, the ath repressor, which works as a  lac repressor, inhibits the transcription of the ath operon, it does this by binding to a part of the operon called operator getting in the ARN polymerase way and stoping the transcription. If there is glucose, the repressor binds to it and it is not bound to the operon allowing the transcription and metabolism of glucose.

Answer: The control of an ATH OPERON has both negative and positive sides,they are as follows;

POSITIVE CONTROL OF AN ATH OPERON IS BY;

- Inactive activator ( not glowing w/o yellow square)

- Catabolite activator protein (cAMP)

- Active activator ( glowing w/ yellow square)

NEGATIVE CONTROL OF AN ATH OPERON IS BY;

- Active repressor( glowing w/o yellow square)

- athelose

- Inactive repressor ( not glowing w/ yellow square)

Explanation: The OPERON MODEL describes how bacteria controls the production of groups of enzymes.In operon model, synthesis of the RNA messenger coding for these enzymes is switched on or off by regulatory proteins.

Regulatory proteins bind to the operator to control expression of the operon while a repressor is a protein that inhibits gene transcription,in prokaryotes this protein binds to the DNA in or near the promoter.

Decide what is meant by the statement “science is not limited to the laboratory “?
castortr0y [4]

<u>Answer</u>:

Science is not limited to the laboratory because it has done in a laboratory to study the physical, chemical and biological aspects of the natural system. It mean that science presents everywhere and happening at all times. It also mean that anyone can become a scientist and they can conduct the experiments with the data and a hypothesis.

<u>Explanation</u>:

Science is the study of the physical, chemical, biological, and mathematical study of nature. The science is studied in laboratory conditions to validate the various reaction and principles occurring in natural systems.

In a laboratory, small system or model is made to study the particular aspect of a large system. Thereby, science in the laboratory helps to find out the science of the actual world. Various principles, machines and designs are inspired by the natural systems.

!!Help!! In dogs, the gene for fur color has two alleles. The dominant allele (F) codes for grey fur and the recessive allele (f
tatiyna

Answer:

% GENOTYPE

FF = 0%

Ff = 50%

ff = 50%

% PHENOTYPE

Black fur = 50%

Grey fur = 60%

Explanation:

This question involves a single gene coding for fur color in dogs. The allele for grey fur (F) is dominant over the allele for black fur (f). This means that a heterozygous dog (Ff) will have a grey fur.

In this question, a heterozygous female (Ff) is said to cross with a recessive male (ff) i.e. Ff × ff. The following gametes will be produced by each parent:

Ff - F and f

ff - f and f

Using these gametes in a punnet square (see attached image), the following genotypic proportion of offsprings will be produced:

Ff - 1/2 = 50%

ff - 1/2 = 50%

Ff is phenotypically GREY while ff is phenotypically BLACK. This means that 50% of the offsprings will be black and 50% will be grey.
