Answer:
Las células cancerosas continúan multiplicándose, sin saber cuándo detenerse y eventualmente destruyendo todas las células buenas.
Answer:
The correct answer is option A.
Explanation:
The histone acetylation catalyzed by histone acetyltransferases and deacetylation catalyzed by histone deacetylases performs a significant role in the regulation of the expression of genes in eukaryotes. Histone acetylation diminishes the affinity of histones towards DNA leading to relaxing or decondensation of chromatin and becomes accessible to the transcriptional apparatus and to perform transcription.
It can be stated that histone acetylation is related to expression or gene or activation and histone deacetylation is related to the inactivation of gene or repression.
Answer:
Only small proportion of energy in the biomass of organisms in one trophic level will ever become part of the biomass of organisms in the next trophic level.
Explanation:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
Hey friend.
Let's figure this out.
A person can be tested for the allele that causes Huntington’s disease because the "DNA SEQUENCE," of that allele is different from that of the normal allele.
Hope this helps. ;)
