Gene expression is initiated largely in response to changes in  the ____________________________ in prokaryotes as opposed to changes affecting the homeostasis of the whole organism in eukaryotes.

Acatalasemia is a rare autosomal recessive condition that results in no expression of the enzyme catalase; however, persons with this condition are usually only mildly affected. The enzyme catalase is found in most organisms and is a protection against oxidative damage, specifically breaking down the highly reactive oxygen species, hydrogen peroxide. Symptoms may include mouth ulcers that disappear with good dental hygiene; with poor dental hygiene, the ulcers can lead to gangrene in the mouth soft tissues. Persons with this condition usually do not know they are affected unless a family member is tested for the mutation. Dejah recently learned that her Uncle Malik had a dental surgery that was complicated by mouth ulcers and gangrenous tissue that had to be removed. The oral surgeon had learned about genetic conditions that affect oral hygiene and recognized that this could be acatalasemia, and ordered genetic testing. Uncle Malik was positive for this recessive condition, having…

Please help with this question. This is not a writing assignment like an expert kicked back to me.

Please help, doesn't it usually start before the promoter or after, please just give me a brief explanation

WHAT ELSE CAN I ADD TO THIS DISCUSSION In general, what is gene regulationand what are the consequences if this process goes awry? Gene regulation is the process used to control the timing, location and amount of genes expressed. The process is carried out by a variety of mechanisms, including regulatory proteins and chemical modification of DNA. It’s key to the ability of an organism to respond to environmental changes. If the gene regulation process goes awry, these alterations are called mutations and can accumulate over a lifetime. Errors in genes that control cell division can cause cancer and other genetic mutations to take place.

The (blank) gene is constitutively active (always making protein).

how do i expand this into 1000 words The methodology employed to identify differentially expressed genes (DEGs) in breast cancer using RNA-Seq data involves several systematic steps integrating data retrieval, analysis, normalization, DEG identification, and functional annotation. Initially, raw RNA-Seq data is retrieved from the NCBI GEO database, specifically from dataset GSE216238 (Nakshatri, 2023), which encompasses samples from both breast cancer and normal tissue. Subsequently, the raw data was imported into Excel for initial analysis, leveraging its widespread availability and user-friendly interface. Gene expression data for breast cancer analysis was obtained from the Gene Expression Omnibus (GEO) database. The GEO homepage (https://www.ncbi.nlm.nih.gov/geo/) was accessed, and the "Query & Browse" tab was selected. Advanced Search: Under "Search GEO DataSets," an advanced search was conducted (https://www.ncbi.nlm.nih.gov/gds/advanced). Keywords "breast" and "cancer" were…
