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>
So basically you have to like multiply and stuff so you would freaking get like 250 or something.
Answer:
Mangrove forest
Explanation:
Mangrove forest exist only in high saline environment. Lake is a closed type body of water so it is expected with the least variation of salinity.
An environment high in carbon dioxide and high in oxygen induce oxygen to bind to hemoglobin. Another factors are an environment under high pressure and an environment under low pressure.
The answer is true as phenotype involves of having to see the organisms character and their morphological features, by this, it is trying to apply to both of the physical and psychological characteristics, making the sentence above as true.
