In a free market system, price controls can include both floors and ceilings.
The government imposes these limitations in order to regulate the retail value of specific goods and services. Rather than have limits on both sides, most items have either a floor or a ceiling imposed on them.
Answer:
Qualitative data simply is the none numerical data which is simply obtained through observations and recording it. It talks about mainly quality. While quantitative data is the numerical data input. It talks about quantity, how much, how many and so on.
The hydrogen bond in polar molecules occurs only in compounds that have hydrogen bonded to N, O, or F.
These very highly electronegative elements create a partial positive charge on the hydrogen.
The H atom is attracted to the partial negative charge on an N, O, or F atom in another molecule.
The hydrogen bond is an attraction but not a true chemical bond such as ionic or covalent bonds. It is much weaker.
However, the hydrogen bond is a strong intermolecular bond.
Answer:
The correct statements are,:
B. Resistance to the anti-viral drug ganciclovir indicates that homologous recombination has occurred.
C. Homologous recombinants of the knockout alleles are desired since they will replace the wildtype allele
E. The embryonic stem cells carrying homologous recombinants of the knockout allele are placed back into a blastocyst and injected into a surrogate mother to produce mice carrying the knockout allele.
Explanation:
<u>wrong statements</u>
A. Illegitimate recombinants have the knockout allele randomly inserted and do not replace the wildtype alleles and may potentially insert into other genes and confound the analysis
D. Resistance to neomycin indicates insertion of the knockout allele but does not distinguish between homologous and non-homologous recombinants
A and D are wrong statement due to the fact that Cells that were transformed with a vector containing the neomycin gene and the herpes tk+ gene are grown in a solution that contains neomycin and Ganciclovir in order to distinguish the transformations that occured through homologous recombination. Any DNA insertion that occurred through random insersion( illegitimate recombinant) will die because the tests positive for both neomycin resistant gene and herpes tk+ gene whose gene product reacts with Ganciclovir to produce deadly toxins.
Messenger RNA (mRNA) sequence is A U U C G G A U U A G A U U A.
Template strand of DNA from which mRNA is synthesized is T A A G C C T A A T C T A A T (complementary to RNA).
DNA sequence of the nontemplate (coding) strand is the same as the mRNA sequence.
