Explain what occurs in cell differentiation and morphogenesis
BigorU [14]
cells become specialized in structure and function, and these are organized into tissues and organs. Activities of a cell depend on the genes it expresses and the proteins it produces. Specific activators turn on the collection of genes whose products are needed in the cell. Materials placed into the cell by the mother set up a sequential program of gene regulation that's carried out as cells divide.Explain what occurs in morphogenesis:The physical processes that give an organism its shape.

Tpy6a [65]

Researchers suggests that we can avoid self-confirming diagnoses by all the given options.

<h3><u>Explanation:</u></h3>

Self confirming of diagnosis of a disease is actually good for a skilled person, but for general persons, it can be very dangerous and can cause severe outcomes. Different diseases have similar symptoms, but the outcomes are very different.

Some insignificant diseases like indigestion, acidity do have symptoms of loose motion, along with severe diseases like cholera, typhoid, dysentery, and acute arsenic poisoning. So its very necessary for checking the actual cause of the disease by differential tests as well as carefully classifying the symptoms by a professional doctor.

Which of the following is an example of post-transcriptional control of gene expression?a. gene amplification contributing to ca
MAVERICK [17]

The correct answer is: b. the removal of introns and alternative splicing of exons

Post-transcriptional regulation includes processes of regulation between transcription and translation such as RNA splicing, capping, addition of poly-A tail,  RNA editing.

RNA splicing represents the process of RNA processing in which newly synthesized pre-mRNA transcript is converted into a mature mRNA. This process occurs only in eukaryotic organism and includes the removal of introns and joining together the exons. RNA splicing might occur during or immediately after transcription and it is performed by spliceosome (complex of small nuclear ribonucleo proteins).

Alternative splicing is a regulated process in which a single gene can code for multiple proteins because particular exons of a gene may be included within or excluded from the final mRNA.
