Question
energy for rho-dependent chain termination? (2 pt) is distinct from any incorporation into the chain. 16. What provides the rho-depen b. Nucleotide hydrolysis associated with incorporation into the chain. c. Torsional stress built into the separating DNA strands. d. There is no energy requirement 17. What is the template for protein synthesis? (2 pt) a. a mRNA strand b. the DNA coding strand e. the DNA template strand d. a protein primer e. None of the above 1 S. Aminoacyl-tRNA Synthetases are involved in which step of translation? (2 pt) a. activation b. initiation c. elongation d. termination e. None of the above 19. The genetic code is said to be degenerate. What does this mean? (2 pt) a. each codon codes for more than one amino acid. b. each anticodon can interact with many different triplet sequences in the mRNA, which may differ in any or all of the three nucleotides. c. many of the amino acids are coded for by different codons. d. the code is universally used by virtually all species. e. None of the above below are restriction enzymes useful for genetic recombination work? (2 pt) a. They cut DNA in the middle of specific sequences. b. They cut DNA independent of the source of the DNA. c. They often generate single stranded tails or "sticky ends" d. There are a large variety of them commercially available. e. All of the above.Explanation / Answer
16. a) ATP hydrolysis
Rho is an ATP dependent helicase that binds to mRNA and pulls away RNA polymerase and DNA template.
17. a) a mRNA strand
It mediates the transfer of genetic information from the cell nucleus to ribosomes in the cytoplasm.
18. C) elongation
19. C) many of the amino acids are coded for by different codons
Different codons specify the same aminoacid
20. c) They often generate single stranded tails or sticky ends
