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

Answer:
Because they are sterile
Explanation:
<em>Mules are considered to be a weak hybrid and not a separate species because they are sterile and cannot produce progeny of their own.</em>
Mules are hybrid products from two separate species - a donkey and a horse.
A species is generally defined as a group of organisms that are capable of breeding to produce fertile offspring. <u>Hence, in order for them to have the potential of being categorized as a separate species, they must be able to produce their own progeny but this is not the case. </u>

Answer:
■Gene sequences would be used to make Probes for both the Southern and Northern blots.
■The probes will be used to view the presence of each gene with the use of isolated genomic DNA obtained from the isolated bacterium
■Each probes hybridized to the genome shows the pathway is isolated and point of the genes were involved in the substrate catabolism
■The carbon source in the isolate is derived from the substrate inducing the catabolic pathway as RNA determine transcripts present
■Probes hybridizing to the same sequences would be used to determine the gene activity for the pathway as seen in the southern one
■since all the genes present in the genome couldn't be identified, the northern would be important to work on
■Catabolic pathway is determined by the same genes. Hence, the need for gene/transcript probes to hybridize to the transcriptome.

Answer:
In early pregnancy, the blastocyst stage continues for about 5 days before the embryo implants in the uterus, or womb. At this stage, stem cells begin to differentiate.
