Hox genes, which are members of the homeotic transcription factor family, establish the segment identity of tissues within the embryo and are essential regulators of the body plan along the cranio-caudal axis (also known as the anterior-posterior axis). This means during embryogenesis, these genes expression follows a precise spatial and temporal colinearity pattern from the 3' to the 5' end of each cluster.
This indicates that Hox genes expressed anteriorly in the developing embryo are typically found at the 5′ end of the same genomic area, a phenomenon known as spatial colinearity. In comparison, those expressed posteriorly are typically found at the 3′ end of the Hox cluster.

We have that for the Question "Does she need to worry about this problem" it can be said that
- If Mary is taking <em>Calcium</em> medication with<u> thyroid hormone</u>,she does not need to worry about this problem
From the question we are told
Marissa has had her entire thyroid gland removed because of a malignant tumor. She takes synthetic thyroid <em>hormone</em> to replace the thyroxine that her thyroid gland would have <u>produced</u>, but she is worried about her blood calcium. <u>Does </u>she need to worry about this problem
<h3>Hormone known as TSH</h3>
Generally normal thyroid feature is watched through the pituitary gland. The <u>pituitary </u>makes a hormone <em>known </em>as TSH that motives the thyroid gland to make thyroid hormone for the body.
the <em>hormone </em>additionally promotes increase of the thyroid <em>gland</em> and likely of thyroid most cancers cells.
<h3 /><h3>Levothyroxine (L-T four )</h3>
Levothyroxine (L-T four ) is one of the most typically given medications. It is given as both physiologic alternative remedy in <em>sufferers </em>with <em>hypothyroidism </em>or as interventional remedy to suppress thyroid-stimulating hormone <em>secretion </em>in sufferers with thyroid cancer.
Therefore
if Mary is taking <em>Calcium</em> medication with<u> thyroid hormone</u>,she does not need to worry about this problem

Answer:
The scientific claim that is most consistent with the findings in the question given is that: histone methylation opens up chromatin at gene R, so transcription factors can bind to DNA more easily.
Explanation:
The transcription of the R gene decreases when histone methyltransferase is inhibited, this proves that histone methylation increases the transcription of the R gene.
When the gene is in the condensed state, RNA polymerase can no longer gain access to the region so as to transcribe the R gene. Thus, in order for the gene to be transcribed, the gene has to be in the open (euchromatin) state.
Histone methylation makes the gene in the euchromatin state.
Therefore, the scientific claim that is most consistent with the findings in the question given is that: histone methylation opens up chromatin at gene R, so transcription factors can bind to DNA more easily.
Answer: we can see the nucleus obviosly in the eukaryotic cell
