<span>The statement "The Miller-Urey experiment is to terrestrial as the meteorite hypothesis is to marine" is true. The Miller - Urey experiment used a rock sample to test the ages of the Earth's atmosphere by passing it in an tube with electric current. Also, the meteorite hypothesis believed that while the meteorite was falling into the Earth, it brought organic molecules that made life happen.</span>
Maltase - cleaves maltose into glucose
Sucrase - cleaves sucrose into glucose and fructose
Lactase - cleaves lactose into glucose and galactose
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.
