Hypothesize what might happen if the deletion mutation was at the end of the gene rather than towards the beginning
GrogVix [38]

Answer:

Deletion mutation usually takes place due to the errors in the process of DNA replication . DNA polymerase slips off on the template strand due to which that part of the DNA is not coded in the daughter strand.

It can skip from one nucleotide (point mutation) to an entire gene. Point deletion can result in frame-shift mutation if it takes place in the beginning or middle of the gene. However, if it takes place at the end of the gene then it may cause no harm.

For example, let us assume the original sequence of DNA as ATG-AGT-CGT-ATA-TAA. It will result in the formation of methionine, serine, arginine, isoleucine, and STOP codon.

Point deletion at the end of the gene results in ATG-AGC-GTA-TAT-AA sequence. Now it will code for methionine, serine, valine, and tyrosine as AA will not code for anything. Hence, the sequence of the protein remains the same.

Hence, if deletion mutation takes place at the last or stop codon of the gene then it will cause no harm or change in the protein sequence. However, if it takes place before that then it may result in frame-shift mutation and thus a mutated protein.

Give an example of a statement that best describes the rhyme scheme of "A Thought on the Inestimable Blessing of Reason".
tia_tia [17]
<span>I don't know if you have any options, but I'd say that the rhyme scheme of this poem is aabbcc, etc. - this means that two lines rhyme, and then the next to lines rhyme, etc. The entire poem is written in the octosyllabic couplet, meaning that each line has 8 syllables (an octave), and the term couplet refers to the rhyme - that every two lines rhyme. </span>

amid [387]
<span>Although a star might look brighter than the Sun, a comparison of its absolute<span> magnitude might help prove that they have the same real brightness.
Absolute magnitude is a concept that compares the absolute brightness of celestial objects. The absolute magnitude of an object is defined as the apparent magnitude it would have if it were viewed at a standard distance of 10 parsecs (32.6 light-years) with no dimming of its light. The more luminous an object, the smaller the numerical value of its absolute magnitude.</span></span>

The block shown above is a cube of halite. Each side measures 3 cm. Find the volume of the cube of halite.
ddd [48]

The block shown above is a cube of halite. Each side measures 3 cm. Then the volume of the cube of halite is 27 cm³.

<u>Explanation:</u>

Step 1:

All the sides of the cubes are equal.

Step 2:

Given,

 a= 3 cm

Step 3:

Volume of the cube = a³

                                 = 3 × 3 × 3

                                 = 27 cm³

Hence, The volume of the cube is 27 cm³
