What could be the consequence of a mutation that changes the sequence of nucleotides in a promoter?

Biology
1 answer:
Korolek [52]3 years ago
4 0

Answer:

The changes in the sequence of nucleotides present within a promoter is a prime cause of the defected transcriptional regulation, which may eventually result in disease. However, not every modification within the sequence of a promoter influences the regulation of transcription, it relies upon the nature and the location of the genetic defect.  

When a mutation results within the sequence of a promoter region it may hamper the usual procedures of gene stimulation by affecting the step by step alignment of the transcription factors at the promoter region. Therefore, as a consequence, a mutation within the sequence of a promoter may result in the enhancement or reduction in the level of mRNA and thus protein.

Bumek [7]

Sternal angle marks the joint between the sternum and the 2nd rib.

Option E.

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

Sternum is the breast bone which is a dorsi ventrally flattened bone present in thorax of human. It gives the support for the ribs where the ribs join. A sternum has three parts - Manubrium sterni, body of sternum and the xyphoid process.

The sternum has attachments of a total of 10 ribs and clavicle. The clavicle and the first rib joins in the Manubrium sterni, and the 3rd to 10th rib joins in the body of sternum. The 2nd rib joins in a facet which is partly in Manubrium sterni and partly in body of sternum. This place id also called the sternal angle. So the sternal angle marks the joint of 2nd rib to sternum.

bekas [8.4K]
Inside of plants, there are xylem cells that carry water and minerals from the roots, to the leaves, when the food then gets dispersed to the rest of the plant. This is similar to the human circulatory system but there isn't a heart pumping blood around. Hope this helps :)
