If a segment of DNA were replicated without any errors, the replicated strand would have the following sequence of nucleotides:
Cerrena [4.2K]

5'-ACTCGTGA-3'-frameshift mutation (number of nucleotides in a DNA sequence is not divisible by three). deletion, one nucleotide in DNA is deleted, in this case A

5'-ATTACGTGA-3'- base substitution, C is substituted with T

5'-ACTACGTGT-3'- base substitution, A is substituted with T

5'-ACTAAGTGA-3'- base substitution, C is substituted with A

Substitution is a type of mutation in whichonly one base is changed. They can be:

• Nonsense mutations-when substitution leads to the formation of a stop codon instead of a codon

• Missense mutations-when one nucleotide is substituted and a different codon is formed

•       Silent mutations-when a nucleotide is substituted and the same amino acid is produced

alexgriva [62]
The most important approach for the nurse to use when applying a nasal cannula is TO MEASURE OXYGEN SATURATION.

Oxygen saturation refers to the fraction of oxygen-saturated hemoglobin as compared to the total hemoglobin in the body.
