mRNA complementary to DNA is produced via - correct answer
✔transcription
what is the promoter region? - correct answer ✔it is a region of a parent DNA
strand that binds to the RNA polymerase and initiates transcription
a gene is.. - correct answer ✔a specific segment of nucleotides in DNA
a single-stranded molecule that contains the information for assembly of a
specific protein - correct answer ✔messenger RNA
a transcription factor is - correct answer ✔a protein that binds DNA and
regulates synthesis of mRNA
T/F? introns are usually present in bacteria - correct answer ✔false

, if RNA polymerase reads the sequence ATCTTA, which sequence will it make
RNA? - correct answer ✔UAGAAU
anticodon is the term applied to - correct answer ✔the part of the tRNA that
interacts with the codon

acid? - correct answer ✔methionine
both transcription and translation occur in 3 steps. what happens during the
elongation step of each process? - correct answer ✔transcription elongation:
the RNA molecule is synthesized
translation elongation: the protein molecule is synthesized
