Answer:
Transcription, mRNA (processing, transport, localization and stability), translation.
Explanation:
- Transcription is regulated in two levels, though chromatin regulation (methylation and acetylation) to loose or increase histone's affinity to DNA and through cis and trans elements such as promoters, enhancers, and silencers (cis) to active/deactivate and RNA polymerase and transcription factors and co-factors (trans).
- mRNA can be regulated using poly-A tails or 5'-caps to shorten or give them more time before they degrade, it could also be spliced to eliminate introns.
- In the translation stage, the regulation occurs during the initiation through a scanning procedure that ensures the 40s ribosomal subunit bind correctly to the untranslated portion of RNA

The only one that makes sense is size. because there could be other minerals the same size. so size wouldn't be a property to help identify
Answer:
Chromatin helps regulate DNA replication.
Explanation:
Chromatin helps condense DNA strands to smaller units that can be easily managed during DNA replication and gene expression. This also prevents the breakage of the strands and facilitates equal distribution of chromosomes during cell division (during mitosis and meiosis).
The answer is pollution, because solar energy is costly, difficult to maintain, and fairly complex.
