What is meant by basal level transcription?.

English
1 answer:
Sati [7]4 years ago
3 0
In cells, some genes are constitutively transcribed. These genes are typically under damped feed forward and positive control mechanisms and their protein products code for basic metabolic machinery and other proteins necessary for cell life. If they weren't there, the cell would die; therefore, it is careful to always transcribe enough new mRNAs to replace those being degraded.

In cases when more of these products are needed - for example, when a cell faces a metabolic challenge - then transcription is upregulated from this basic or basal level. The cell meets its need; negative feedback at higher transcript concentrations or copy number reduces transcription of the gene or genes involved in the response, and their rate of transcription goes back to the basic level.

For a superb example, read up on hypoxia inducible factor and the cassette of genes it regulates.

Answer:

<u>A. Young and wealthy, Newland Archer arrives at the opera and greets his party.  He is newly engaged to May Welland and is concerned with finding the perfect time to announce their betrothal. He becomes distressed when introduced to  May's shameful cousin, Ellen</u>

<u>Explanation:</u>

Remember, in this line from the story in chapter 3 which about that conclusion, "A group of young men and girls were gathered about her, and there was much hand-clapping, laughing and pleasantry on which Mrs. Welland, standing slightly apart, shed the beam of a qualified approval. It was evident that Miss Welland was in the act of announcing her engagement, ...Archer paused a moment. <em>It was at his express wish that the announcement had been made,</em> and yet it was not thus that he would have wished to have his happiness known<em>. To proclaim it in the heat and noise of a crowded ball-room was to rob it of the fine bloom of privacy which should belong to things nearest the heart."</em>
