You are a graduate student at the university of iowa and working as a teaching assistant for a freshman introductory biology course. two of your students have come to you with a ques- tion about the sequence of an mrna transcribed from a gene. the original dna sequence from which the mrna was transcribed reads: tgacgatcgta. the students were asked to provide the sequence of bases in the mrna and came up with the following mrna sequence: actgctagcat. they are confused because their answer does not match the answer in the book. briefly explain the very common mistake they made and what the correct sequence is.

The corret DNA sequence is ACUGCUAGCAU.

Explanation: The common mistake that they make is, they forget to replace thymine with uracil as a base pair of Adenine. During DNA transcription Thymine is replaced by Uracil in production of messenger RNA. Uracil is a de-mythylated form of thymine and requires less energy to produce.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
