Organize the stepsof Transcription and mRNA Processing A. RNA Polymerasereaches a terminator sequence in the DNA and the mRNAand RNA Polymeraseis releasedfrom the DNA.
B. mRNA is edited by removing the introns and leaving the exons.
C. Ligase seals exons together.
D. RNA Polymerasereads DNA strand and builds the complementary strand of mRNA by adding nucleotides.
E. RNA Polymerase finds thepromoter region andattaches to DNA.
F.5’ cap and 3’ Poly A tail are added to the mRNA.

Asmall number of finches are removed randomly from the wild and placed in a protected bird area. they are given as much food as they need and have plenty of space. why would natural selection not occur in this population? a. there is no reason for genetic mutation to occur. b. the birds compete for limited resources, c. the population has not reached carrying capacity. d. there is no genetic variation in the finches.

Competition occurs between species when

Scientists are conducting a study on the effectiveness of a new drug on memory loss. they are giving some of the test subjects the new drug to find out if it improves their long-term memory. which are possible limitations of this study? check all that apply. a) test subjects may want to participate in additional experiments. b) test subjects may think they should be paid more. c) test subjects may get bored and want to quit early. d) test subjects may have to travel during the experiment. e) test subjects may have full-time jobs. this is multiple choice. you for the !
