olya-2409 [2.1K]

<h3><u>Answer;</u></h3>

b). Activation of an upstream guanine nucleotide exchange factor

<h3><u>Explanation</u>;</h3>

<em><u>When a ligand activates the G protein-coupled receptor, it induces a conformational change in the receptor that allows the receptor to function as a guanine nucleotide exchange factor (GEF) that exchanges GDP for GTPthus turning the G protein-coupled receptor on.</u></em>
The activated G-protein then dissociates into an alpha (G-alpha) and a beta-gamma complex.

What would happen if there was a sudden increase in the amount of greenhouse gases in Earth's atmosphere

Harrizon [31]

There would be a much more severe cause of global warming if there is a sudden increase in greenhouses gases. With greenhouse gasses such as carbon dioxide, the heat of the earth cannot be penetrated through the atmosphere and will be trapped, the sunlight also cannot be reflected.

The same sentences are written with a substitution, deletion, or insertion, much as a gene may have a substitution, deletion, or

strojnjashka [21]

Answer:

The question is incomplete, the complete question has been added as an attachment.

THE DGR AN represents deletion mutation

THE RED ANA TRA N represents insertion mutation

THE FOX WTS RED represents substitution mutation

Explanation:

Mutation is a change in the nucleotide sequence of a gene. It can be of different types depending on how it occurs. A deletion mutation is that which involves the removal of one or more nucleotide base from the sequence.

An insertion mutation is the addition of one or more nucleotide bases to the sequence.

A substitution mutation is the replacement of one or more nucleotide base in a sequence.

The original sentences were:

1. THE RED ANT RAN

2. THE FOX WAS RED

3. THE DOG RAN

The three sentences that mutated/changed are:

1. THE DGR AN- in this sentence, letter O which represents one base is missing due to removal, making the original sentence (THE DOG RAN) alterated. Hence, this represents an example of deletion mutation.

2. THE RED ANA TRA N - in this case, Letter A has been added in between N and T. This makes the original sentence (THE RED ANT RAN) altered. Since addition of letter (base) occurred, this represents an example of insertion mutation.

3. THE FOX WTS RED - In this case, letter A in "WAS" was replaced by T, making the original sentence (THE FOX WAS RED) altered. Since a replacement of letter (base) is the case here, it represents an example of substitution mutation.
