Styrene, or C6H5-CH=CH2, can form even lengthy chains, via free radical polymerization. This involves the breakage of the double bond that allows the addition of another molecule of styrene. Repetition allows the addition of another, and yet another, styrene molecule. The process can be controlled to limit the number of additions. Another addition polymerization involves carbocations. Double- or triple-bonded compounds interact with acids to form positively charged carbocations. These can combine with additional molecules to form lengthier carbocations capable of further repeating the process.

Which has the most buffering capacity at pH -6?

kati45 [8]

Answer:

D. A 1M solution of Alanine

Explanation:

Buffering capacity is the capacity of a solution or substance to change the Ph of another substance when added to it in 1, so the buffering capacity of all of them, since they have the same Ph, would depende solely on the amount of moles os the given substance that you will add, in this case the substance that has the most matter would be D. A 1M solution of Alanine, that option would have the most buffering capacity since it is a full mole of matter.

Explain why an mRNA transcribed from the template strand of the SIRT3 gene in normal stomach ( NS ) cells is translated to produ

Ivanshal [37]

Answer:

Explanation:

The double-stranded DNA molecule has the potential to store genetic information in either strand, although in most organisms only one strand is used to encode any particular gene.

The template strand is the non-coding strand. The coding strand of DNA is the non-template (mRNA-like) strand (see attachment).

Thus, genetic information is expressed by transcription of the non-coding (template) strand of DNA, which produces an mRNA molecule that has the same sequence as the coding strand of DNA. Therefore, if a mRNA is transcribed from the non-template strand, the genetic information will not be contained in that strand and it would not produce a correct protein.
