Human reproductive cloning should not now be practiced. It is dangerous and likely to fail.
Coal or oil are two of non renewable resources (:
Answer:
Men cannot be carrier of recessive X linked trait as, it only contain X chromosome which means that the X linked traits are get inherited from mother which are get displayed. The female are expressed X linked disorder during homozygous for disorder and they become carriers. So that means that the traits are related with X chromosome are never be carried by the men.
importance of a probe
in hybridization process, molecular biologist label a short fragment of DNA or RNA, usually 10-1000 bases long tagged with a radioactive or fluorescent molecules. this fragment is usually referred to as hybridization probe.probe important both in southern and northern blotting processed because it is used to identify a certain sequence of DNA or RNA in a pool several sequences that have been obtained using nuclease.
process of labeling DNA sequence with a probe
after the DNA strand has been cut into several fragments using enzyme DNA nuclease, the fragments are separated using gel electrophoresis and then denatured using hcl to obtain strands. the single strand are then transferred to nylon membrane that has positive charge. the next step is where probes come in. to detect the DNA sequence of interest the nylon membrane is treated with solution containing tagged probes. since the probes have complementary sequence to the target sequence, it bind to that DNA sequence and detected later using X-ray film.
Yes Mothballs are an active ingredient and the active ingredient could either be paradichlorobenzene or naphthalene .Each of those active ingredients can react to different health problems if its exposed high enough .SOO slowly mothballs turn from solid to Toxic vapor .
