Question

5. Which of the followin g is After the DNA unwinds only one strand acts as a compliance The two strands only act as a plate when paired In prokaryotes the binding of RNAP the two strands After the DNA unwind hath DNA strands at templates occurs randomly on either of of RNA polymerase to unwound DNA Occurs 14. What is an anticodon? The three RNA behaal with nifie umino acid. The three RNA bases that air with a c fic codon in an RNA- The four rRNA hoses that pair with a specifle amino acid. The four DNA bases that als with a specific amino acid 15. Translation uses and to synthesize mRNA, DNA, amino acids mRNA, RNA polypeptide chains mRNA, RNA, polypeptide chains TRNA, RNA amino acids 10. The gel in the following diam b ined by forming a chain termination seguem fragment of DNA. Based on this eel what is the seguence of the DNA fragment ACTAGCTCGCA ACGCTCGATCA AAATTCCCCGG d. GGCCCCTTAAA ained by performing a chain termination sequence analysis on a 17. What happens in the presence of high cellular concentrations of tryptophan? the repressor attaches to the DNA but transcription proceeds the repressor binds to tryptophan and then leaves the operator tryptophan binds to the repressor, which then binds to the operator tryptophan binds to the operator and prevents transcription 18. Which mutation can potentially affect future offspring? a. athymine dimer, resulting from too much sunbathing b. a deletion of a gene segment in a stomach cell chromosome a point mutation in a salivary glad cell, resulting from a viral infection a base pair substitution during the early cell division of an ovarian germ cell 19. Why do fragments of DNA separate when using gel electrophoresis? A movement through a sieving medium by positively charged DNA molecules attracted by a negative pole. Charged DNA molecules are repulsed by the electrically charged gel ions. A diffusion gradient acts as a sieving medium through which DNA fragments are moved. It is a sieving medium through which DNA molecules are moved by electrical forces. that code for a heromone or cellular protein in one species can be inserted into the genome of a different species ferent species. What would be the name given to a cellular substance that is produced in this way? transgenic product b. trans-species C. purified product none of the above CAO
