Answer:
The options to this question are missing, they are:
A) All the proteins the cell creates from the miscopied strand will do different jobs than the old ones.
B) Any miscopied DNA will be replaced with an accurate DNA copy once the cell divides.
C) Both new DNA strands will end up together in a new cell, and the inaccurate one will be discarded.
D) If the new sequence codes for the same amino acid as the original cell, it will function normally.
THE CORRECT ANSWER IS D
Explanation:
What occured to this cell replicating its DNA is called MUTATION, which is a change (small or big) in the nucleotide sequence of a DNA. The miscopied base will alter the nucleotide sequence of the DNA. Since a single base is involved, it is referred to as a POINT MUTATION.
A point mutation, such as the one in this case, can produce varying effects in the resulting organism. The mutation can either lead to a different protein in that particular sequence the mutation occured or have no effect on the organism.
The mutation will have no effect on the organism in a case where the base that was miscopied produced a codon that codes for the same amino acid as the original codon. Hence, the same protein will be produced and have both effect on the cell. This is possible because of the degenerate nature of the genetic code, as more than one codon codes for a given amino acid.
B. Identify the species of the beetle and the species of both trees.
C. Determine why the beetle is eating one tree but not the other.
D. Recommend a treatment that will keep the beetles from eating the trees.
ANSWER: B. identify the species of the beetle and the species of both trees (quizlet)
The botanist should firstly study the interaction of these organisms in the ecosystem by identifying the species of the beetle and the species of both the trees. Therefore, the correct option is B.
A species is a group or organisms that can interbreed and produce viable offspring. The concept of species is used to define a unique type of organism, and it is the basic unit of biological classification.
Species are considered to be different from one another if they are unable to interbreed and produce offspring that can survive and reproduce. This definition of species is known as biological species concept.
In the case given in the question, the botanist should first identify the species of both the beetles and the trees. Then try to deduce a relationship between them which could clarify that the reason of the beetles feeding on those specific trees. Hence, the correct option is B.
