Answer:
B. It is done by humans to select certain traits useful to us.
Explanation:
There are two main types of selection: natural and artificial. Natural selection is all of the other answers, it is seen over generations and allows the fittest to survive. It also occurs with no human intervention. However, artificial selection is done by humans. It occurs when humans breed animals to best fit their needs. This is best seen in dog breeding.
Answer:
The number of artificial mRNA 3 nucleotide codons that would be possible is eight (8), which are: AAA, AAG, AGA, GAA, AGG, GGA, GAG, and GGG.
Explanation:
The arrangement of the nucleotides within the codon permit repetition. The adenosine triphosphate is designated as A, while the guanosine triphosphate as G. The possible number of codons that can be formed from this two available nucleotides is 2 to the power of 3 = 8
These codons are: AAA, AAG, AGA, GAA, AGG, GGA, GAG, and GGG.
Answer:
what grade are you? because im only grade 5
RNA synthesis depends on RNA polymerases (RNAPs). This is the enzyme
that faciliates copying a sequence of DNA which is the first step
leading to gene expression. This multi-step process is important for
researchers to understand especially in relations to studying how
genetics influence disease processes.
