unit 6 bio Exam 2026 Questions and
Answers
If adenine is one, thymine must be on the other strand - Answer -how does the
DNA structure cause the number of purines to equal the number of pyrimidines as
observed by Chargaff?
the rna strand was transcribed from a dna strand with the sequence TAACGCCTT -
Answer -a strand of RNA has the sequence AUUGCGGAA. what explanation can
be made about how this strand came to be?
codons code for the particular amino acids that get assembled - Answer -what is
the importance of codons during the process of protein synthesis?
messenger rna is an output for the process of transcription and an input for the
process of translation - Answer -transcription and translation, the two main
processes involved in protein synthesis, have distinct molecular inputs and outputs.
which statement about inputs and outputs in these processes is true?

, am enzyme called ligase binds fragments of dna together - Answer -which
component of dna replication only occurs on the lagging strand of dna and not on
the leading strand?
UAGGCU - Answer -if a segment of dna has the sequence ATCCGA, what would
be the complementary mrna sequence for that segment?
dna is double stranded and uses a deoxyribose as it's sugar, while rna is single
stranded and uses ribose as its sugar - Answer -(model #7) which statement about
the 2 structures seen in the model are correct?
