Make a frameshift mutation use brackets to indicate how the reading frame would be altered by the mutation
Paraphin [41]

Answer:

Original reading frame=> (ATG)(CGT)(CCA)(TGA)

Altered reading frame => (ATG)(CAC)(GTC)(CAT)(GAG)

Explanation: A frame shift mutation is a type of mutation in which there is addition or deletion of one or more nucleotides in a DNA sequence which results in alterations in the original reading frame of the DNA sequence. In the altered reading frame above two nucleotides were added at positions 4 and 5 thereby changing the subsequent reading frame of the DNA. Frame shift mutation can result in permanent change in DNA sequence during replication and subsequently in altered RNA sequence during transcription and altered amino acid sequence of the final gene product.

Which factor is least likely to affect the results and interpretation of a functional MRI?
fiasKO [112]

Answer:

None of the given options is correct. The correct solution is "Sprained ankle".

Explanation:

  • Brain activation is assessed by functional MRI via identifying causes an increase in blood flow. The assumption that brain blood flow and neural activity are linked is the basis of this methodology.
  • MRI allows excellent visualization of the structure of the ankle, allowing ligament defects and their related osteochondral including tendon disorders to be correctly identified. In patients with such an uncertain psychiatric history although with equivocal otherwise complicated psychiatric exams, MRI can be particularly useful for early diagnosis of syndesmotic lesions.  

All those other alternatives are not linked to a working MRI. Then the option above is appropriate.

andre [41]

Deforestation weakens this process, leading to irregular rainfall patterns including drought and flooding.
