Answer:
The type of mutation responsible for changing a base in the mRNA strand, without changing the coding aminoacid or protein, is called a <u>silent</u> mutation.
Explanation:
In a silent mutation occurs the change of a nitrogenous base in one of the codons that encodes an aminoacid, without changing the aminoacid or altering the structure or function of the protein to be synthesized.
In this type of mutations the change of the base does not mean the change of the aminoacid, because some aminoacids can be coded with more than one codon. In the case of Leucine, the codons that encode it are CUU, CUC, CUG or CUA, so even if a base changes, the final protein will be the correct one.
For the other options:
- <u><em>Missense</em></u><em>: the change of the base in the DNA chain implies the change of the codon in the mRNA and of the encoded aminoacid, in that way a structural and functional alteration of the synthesized protein occurs. </em>
- <u><em>Nonsense</em></u><em>: the change in the nitrogenous base in the DNA leads to the coding of a termination codon, so that the protein is ultimately incomplete.</em>
- <u><em>Insertion</em></u><em>: in this case there is the addition of more nitrogenous bases to the DNA chain, with respect to the original one.</em>
I believe the correct answer would be C. Sartorius i believe this is the answer, after doing some research on gO0gLe.
A triploid cell is the structure form during angoisperm fertilization. The cell are created in the process known as double fertilization into the endosperm which is mostly are polyploid. These are typicallly triploids that is they contain three sets of chromosomes but they varies widely from diploid (2n) to 15N.
Answer:
b. Community art making
Explanation:
The AIDS Memorial quilt ia a very large and enormous memorial which celebrates the lives of the people who became victim to AIDS and died due to causes related to AIDS. It is the largest portion of the community folk art.
As the <u>community art making</u> is defined as the method of art-making involving the professional artists and the communities which are self defined through the collaberative artistic expression.
Hence option B ) Community art making is the right option.
