Answer: The correct answer is B) Frameshift mutation.

The given  mRNA sequence is GGU-GCU-CCU-AUU. When a nucleotide is added at the fourth location in the chain, it entirely changes the frame from the insertion of the nucleotide till the end of the gene sequence. This is called a frameshift mutation.

This is because after adding a nucleotide, a new frame is generated that will code for different amino acids and therefore a different protein will be synthesized.

On the contrary, chromosomal mutation is an abnormality in the chromosome ( in terms of number or structure) whereas substitution mutation is the one, which exchanges one base with another. Deletion of base also results in the frame-shift mutation.

Answer:

The correct answer is option B. "frameshift mutation".

Explanation:

Frameshift mutation is a type of genetic mutation characterized by changing the way a mRNA sequence is read in the ribosome, either by a deletion or an insertion. In this example, a nucleotide is added at the fourth location in a mRNA sequence with the codons GGU-GCU-CCU-AUU. This insertion would change the way the mRNA sequence is read in the ribosome, altering the second codon and therefore all the following codons in the sequence. Therefore, this is an example of a frameshift mutation.

What main sub layer of the earth does all the action take place at?
Stella [2.4K]
The Earth can be divided into one of two ways – mechanically or chemically. Mechanically – or rheologically, meaning the study of liquid states – it can be divided into the lithosphere, asthenosphere, mesospheric mantle, outer core, and the inner core. But chemically, which is the more popular of the two, it can be divided into the crust, the mantle (which can be subdivided into the upper and lower mantle), and the core – which can also be subdivided into the outer core, and inner core

Which substance is completely consumed in a chemical reaction?
Rudiy27

Answer:

Limiting Reactant

Explanation:

Observe the answer choices:

A) Limiting Reactant; a limiting reactant, as can be seen from the name, is the reactant that <em>limits</em> the amount of products can be made. This is because the reaction can only go on if there is enough reactants. However, the limiting reactant is the one that will run out first, so it's going to be completely consumed.

B) Reactant; a reactant is the thing that is being consumed in a reaction. However, reactants aren't always completely consumed. There's something called an excess reactant, which is essentially the opposite of a limiting reactant in that when the limiting reactant is used up, there's still some excess reactant left - because it's in <em>excess</em> / there's more than enough remaining. So, this is incorrect.

C) Products are the ones that are created during the chemical reaction, so they aren't consumed in any way. Thus, this is wrong.

The answer is limiting reactant.

Hope this helps!
