Which of the following mutations could result in a truncated protein? Choose all that apply. Which of the following mutations co
castortr0y [4]

Answer:

A truncated protein refers to a protein that gets shortened due to a mutation, which does not allow the process of translation to take place properly. The formation of a truncated protein can take place due to a frameshift mutation of one or two base pairs. In such kind of mutation, a single or two base pairs get withdrawn from the sequence resulting in the formation of a completely changed triplicate codon sequence, which may result in the generation of a truncated protein comprising a different set of amino acids.  

A nonsense mutation can also result in the formation of a truncated protein. A nonsense mutation generally codes for certain kinds of amino acid, however, post mutation can get converted into a stop codon. This transformation can result in the formation of a truncated protein.  

Deletion or insertion at the chromosomal level can also result in the formation of a truncated protein. As insertion and deletion of a certain concentration of DNA can probably lead to the formation of a novel codon that can either be a nonsense codon or a stop codon, which may eventually result in the formation of a truncated protein.  

Hence, the correct answers are statements 1st, 2nd, 3rd, 4th, and 6th

Plants use carbohydrates to build things such as cellulose. How do plants acquire these building blocks to build mass?
RSB [31]
Plants make carbohydrates through the process of photosynthesis. When the leaves of the plants absorb the sunlight, they use this energy to combine water with carbon dioxide. The by-products of mixing carbon dioxide and water are glucose and cellulose.

<span>Photosynthesis is a unique trait that separate plants from other living organisms. They can provide the necessary nutrients to help sustain themselves and survive for longer periods of time. When carbohydrates are in excess, plants have the ability to store and use them when one of the ingredients of photosynthesis is not available. </span>
