a. Yes; electroporation or chemical transformation can be used to make Enterococcus competent, b. Yes; electroporation or chemical transformation can be used to make non- competent Streptococcus mutants, from which genes can be inserted into a cloning vector and introduced into Enterococcus. and then genes from Streptococcus can be introduced via a cloning vector. A microbiologist would like to use a noncompetent genus of streptococcal bacteria, Enterococcus faecalis, as a cloning host to express genes from Streptococcus pneumoniae, which is naturally competent. Is this possible? Select one: • BIO250_Saylor_V3 • Unit 24: Genetic Engineering and Recombinant DNA Started on Monday, December 9, 2019, 12:19 PM State Finished Completed on Monday, December 9, 2019, 12:56 PM Time taken 37 mins 14 secs Grade 81.00 out of 90.00 ( 90 %) Question 1 Correct 4.50 points out of 4.50 Flag question Question text Question 2 Correct 4.50 points out of 4.50 Flag question Question 3 Correct 4.50 points out of 4.50 c. No; competence factor is an essential protein that enables the uptake of foreign DNA, d. Yes; since the cloning host and the DNA to be introduced are both from bacteria that are streptococci, natura used. therefore a cloning host such as Enterococcus that lacks competence factor protein is unable to be transformed by e a. Primers Polymerases dNTPs High temperatures Which of the following components of PCR ensures amplification of the target DNA sequence only, despite th Select one: Feedback The correct answer is: Yes; electroporation or chemical transformation can be used to make Enterococcus competent, and then genes from Streptococcus can be introduced via a cloning vector. Question text Feedback The correct answer is: Primers Question 4 Correct 4.50 points out of 4.50 Flag question a. DNA is amplified for one cycle. DNA is denatured at 95 o C. DNA is reannealed at 50 o C Primers are extended at 72 o C. Which of the following PCR procedures includes all of the others? Select one: a. cloning small gene sized DNA fragments produced by breaking chromosomal DNA with b. cloning large DNA fragments produced by breaking chromosomal DNA with ultrasonic c. cloning random PCR fragments amplified from genomic DNA. d. cloning large DNA fragments produced by restriction endonuclease cleavage. waves. ultrasonic waves.

Ǫuestion 2 1 / 1 point Which dramatic change in the alternation-of-generations life cycle led to the protection of all phases of the life cycle and the formation of seeds? transition from a dominant gametophyte generation to a dominant sporophyte generation transition from a dominant sporophyte generation to a dominant gametophyte generation Ǫuestion 3 1 / 1 point Which structure(s) allow the sporophyte of vascular plants to be protected against drying out? the waxy covering of leaves, called the cuticle small openings in the leaves, called stomata guard cells that surround each stoma all of these structures protect the dominant sporophyte from drying out Ǫuestion 4 1 / 1 point Why are the bryophytes called nonvascular plants? because they are specialized for transporting water and organic nutrients because their roots, stems, and leaves lack vascular tissue because they protect their embryo because they produce wind-blown spores Ǫuestion 5 1 / 1 point Which generation is dominant in the bryophytes? the generations are equally dominant the sporophyte the gametophyte there is no sporophyte generation in bryophytes Ǫuestion 6 1 / 1 point Which of the bryophytes are typically low-lying, due mostly to their need for moisture and lack of vascular tissue? the mosses the liverworts the hornworts all of the bryophytes are low-lying Ǫuestion 7 1 / 1 point Which structure of the moss protects the embryo from drying out? the archegonium the antheridium the sporangium the stalk Ǫuestion 8 1 / 1 point Cooksonia were the ﬁrst plants; they had wind-blown spores, , leaves, and roots. nonvascular; branches vascular; seeds nonvascular; seeds vascular; branches Ǫuestion 9 1 / 1 point The roots of today's lycophytes are much like were in early vascular plants; the vascular tissue is . roots; centrally placed stems; centrally placed leaves; only found at the perimeter branches; only found at the perimeter Ǫuestion 10 1 / 1 point Pteridophytes, or ferns and their allies, are vascular plants with . seed-producing; microphylls seedless; microphylls seedless; megaphylls seed-producing; megaphylls Ǫuestion 11 1 / 1 point Microphylls .
