A
B is wrong because mitochondria would likely absorb the stain even if it was dead.(And most cells that have been treated are dead anyway). C and D are just throwaway answers, you usually want to avoid the word "always" when drawing conclusions.
Answer:
1, Promoters
2.transcription bubbles
3. transcription
4. repressors
5. Primers
6. consensus sequences
Explanation:
.1. DNA sequences that direct RNA polymerase to the initiation site are called _____Promoters _________.
2. RNA synthesis complexes containing DNA, RNA, and polymerase are called ___transcription bubbles___________.
3. RNA synthesis (tRNA, mRNA, and rRNA) in general is called _______transcription_______.
4. The expression of beta-galactosidase requires the induction of operons by removal of _repressors_____________.
5. Unlike DNA synthesis, RNA synthesis does not require ___primers___________.
6. ___consensus sequences___________ are deduced by comparing many related DNA sequences.
B connective; bind and support the body
Answer:
c) has a lower number of carbon-carbon double bonds than sample B.
Explanation:
The two fat samples were compared on the basis of their melting point. Fats with no carbon-carbon double bonds in their hydrocarbon chains are called saturated ones. These fat molecules are packed tightly and have a higher melting point. On the other hand, the fats with one or more double bonds between carbon atoms are said to be unsaturated ones. These unsaturated fats have a lower melting point as the kink produced by double bonds does not allow their tight packing. Therefore, sample A with a higher melting point should have a less number of C-C double bonds than sample B.
