Answer:

The correct option is d. confer passive immunity.

Explanation:

An antitoxin is an antibody formed in an organism in response to the presence of a bacterial toxin inside, which it can neutralize. We speak of passive immunity, when it is obtained by the passage of antibodies (antitoxins) to the individual in a natural or artificial way, having as main feature that it is short-lived, since they remains only until the transferred antibodies or lymphocytes disappear.

VladimirAG [237]

Answer:

Explanation:

Symbol          Representation

I-                     laci mutant cannot bind to the operator

Is                    laci mutant always bind to the operator

OC                 Operator mutant that prevent repressors binding

F’                    the wild type operator, O+, and laci gene on a plasmid

L                     lacZYA genes

I+ O+ L+   Inducible

I+ OC L+   Constitutive

I+ OC L+, F’   Constitutive

I- O+ L+, F’   Inducible

Is O+ L+    no transcription

Is O+ L+, F’   no transcription

What is the purpose of woolite when extracting DNA?
Nitella [24]
Purpose:Extraction and successful PCR amplification of DNA from humanremains in historical and forensic cases have great importance. The purpose of this study is to demonstrate the efficiency of a method of DNA extraction and PCR amplification of embalmed dried human cadaveric skeletal fragments and teeth specimens from Sokoto, Northwestern Nigeria.
Materials and Methods: The efficiency of a method of DNA extraction and PCR amplification was tested on thirteen (13) embalmed dried human cadaveric skeletal fragments and nine (9) teeth specimens from Sokoto, Northwestern Nigeria were used in the study.
Results: Of the 13 embalmed dried human cadaveric skeletal fragments, 12 (92.3%) samples amplified with apparent bands. For the 9 embalmed dried human teeth specimens, 7 (78%) samples amplified with apparent bands.
<span>Conclusion: The study has shown that our method of DNA extraction and PCR amplification was efficient on embalmed dried human cadaveric skeletal fragments and teeth specimens, from Sokoto, Northwestern Nigeria.</span>
