(B)Radioactive compounds

(C)Polyvinylchloride

(D)All of above

  1. A recombinant DNA plasmid construct containing an antifreeze protein gene promoter from ocean pout attached to the cDNA for salmon growth hormone can be used to produce rapidly growing fish for aquaculture. Transcription from the AFP promoter is stimulated by cold conditions; therefore transgenic fish containing this construct synthesize large amounts of growth hormone when they are raised in cool water. Increased production of growth hormones causes transgenic fish to grow faster than native nontransgenic strains. Bovine oocytes were incubated for 24 hours at 4°C in the absence (control) or presence of different types of AFPs or antifreeze glycoprotein (AFGP), a carbohydrate-rich type of AFP, and then fertilized with bovine sperm.

(A)AFPS as Cryoprotectants of Human Tissues

(B)The AFP- and AFGP-treated oocytes show fertilization rates similar to those of fresh oocytes.

(C)AFPs can provide cold protection of oocytes that will maintain their ability to be fertilized.

(D)All of above.

  1. This level is applicable to clinical, diagnostic, teaching, research, or production facilities in which work is done with indigenous or exotic agents which may cause serious or potentially lethal disease after inhalation.

(A)Biosafety level 1

(B)Biosafety level 2

(C)Biosafety level 3

(D)Biosafety level 4

  1. Biosafety level

(A)A biosafety level is the level of the biocontainment precautions required to isolate dangerous biological agents in an enclosed facility.

(B)The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4).

(C)In the United States, the Centers for Disease Control and Prevention(CDC) have specified these levels.

(D)In the European Union, the same biosafety levels are defined in a directive.

(E)All of above.
