Answer:

This mutation will produce a conformational change capable of maintaining the receptor continuously in its activated mode

Explanation:

G proteins are inactive when guanosine diphosphate (GDP) is bound, while they are active when guanosine triphosphate (GTP) is bound

Although macroscopic observations of microbial growth can provide much valuable information, microbiologists often follow such o
melisa1 [442]

Answer:

Explanation:

As a microbiologist there are different methods are devised for characterization of microbes.such as Macroscopic analysis and microscopy method.

With the help of microscope the needed information about the individual cell such as individual cellular characteristics can be obtained, the magnification help to provide the features such as size, shape and motility of the microbes which helps to know the specific microbes characters.

When handling an unknown environmental microbe, with help of the cell characteristics of the microbes obtained using the microscope, the identity as well as metabolic characterization can be known such as the type of environment the microbes can survive in(aerobic or anaerobic), the source of food.

No growth was observed on the control plate.

The growth on the control plate indicates that the aseptic technique devised in the model was an adequate method for the prevention of the control plate from been contaminated.

What are the structural characteristics that give the phosphoanhydride bond its high-energy status?
Bas_tet [7]

Answer:

The answer to the given question out of the four options provided is given by:

Option a. Hydrolysis products are more resonance stabilized.

Explanation:

The answer selection to the above question can be justified as Phosphoanhydride on hydrolysis releases free high energy as the bonds formed by phosphoanhydride are the bonds with high energy.

Therefore, the product of hydrolysis after releasing this energy is more resonance stabilized.

Base excision repair (BER) differs from nucleotide excision repair (NER) in which of the following ways?
postnew [5]

The correct answer is:  5) NER recognizes helix distortions, while BER recognizes specific base damage.

DNA damage that occurs as a result of radiation, oxidizing reagents, chemicals and other mutagens can be repaired. Excision repair repairs single strand DNA damage and it includes:

• Nucleotide excision repair (NER)-it detects and repairs types of damage that distort the DNA double helix such as those of UV radiation (thymine dimers); not only the damaged nucleotide(s) are removed but also a surrounding patch of DNA

• Base excision repair (BER)-it detects and removes certain types of damaged bases (small, non-helix-distorting bases); enzyme glycosylase is responsible for this type of repair
