- Which of the following causes epigenetic modifications to DNA that affects gene expression without changing the DNA sequence? Base pair expression. DNA methylation. Mutation in regulatory sites. Gene knockout.Which of the following about DNA methylation in prokaryotes is FALSE? DNA methylation is catalyzed by DAM methylase on adenine bases. DNA methylation is used by the mismatch repair proteins to distinguish which strand has the correct base when there are mismatched base pairs. Full methylation of both DNA strands depends on the cell's nutrient status Immediately after DNA replication, each daughter helix contains one methylated DNA strand, the newly synthesized strand.Which of the following statements regarding complementary molecules in transcription is false? Group of answer choices The sense strand is complementary to the template strand The transcribed RNA is complementary to the noncoding strand The coding strand is complementary to the antisense strand The transcribed RNA is complementary to the coding strand
- During transcription, the DNA can be modified by the enzyme DNA methyltransferase and will enhance the change of: Select one: a. Adenine into Thymidine b. Thymidine into Cytidine c. Uridine into Cytidine d. Cytidine into Thymidine e. Guanine into ThymidineWhich of the following types of enzymes is primarily responsible for setting up the genetic code? 1.) Kinases 2.) DNA ligase 3.) DNA gyrase 4.) peptidyl transferase 5.) aminoacyl tRNA synthetases (charging enzymes)Mutations can be caused by which process? faulty DNA repair nondisjunction base sequence deletion All of the above
- Which of the following are affected by changes in DNA methylation? Choose all that apply. The interactions between specific proteins and DNA sequences. The sequence of a trans-acting regulatory element The sequence of a cis-acting regulatory elementWhich of the following components is involved in the initiation of transcription? Group of answer choices promoter primer start codon originIn order for transcription to occur, the DNA molecule must be "unzipped". Messenger RNA is then produced using one of the DNA strands as a template. As the mRNA lengthens, it separates from the DNA strand. The two DNA strands then come back together. True False
- TRUE OR FALSE. Non-homologous end-joining as a DNA repair mechanism does not result in loss of nucleotides as a result of a double-strand break.Which of the following statements about the transcription process is correct? a. A protein is made from the RNA base sequence b. A protein is made from the DNA base sequence c. RNA is made complimentary to DNA d. DNA is made complimentary to RNAWhich of the following causes transcription termination in bacteria? RNA polymerase runs out of nucleotide triphosphates. All of the other answers are correct.
