Why are well-defined reading frames critical in protein synthesis? a. without a well-defined reading frame, the mrna would be transcribed back into dna. b. without a well-defined reading frame, the ribosome is unable to bind to the mrna. c. without a well-defined reading frame, the peptide made from a given sequence could be completely different. d. without a well-defined reading frame, the resulting protein would be transported to the cell surface.

C

Explanation:

During the translation of an mRNA, it is read in a sequence of three nucleotides called codons. Therefore, a single strand of DNA or RNA will have three reading frames.  Only one is biologically relevant and is referred to as the open reading frame because it is translated to the ideal protein. A shift in the reading of the frame can result in a wrong peptide.

answer; polycythemia is the correct answer;

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
