DNA ligase is an enzyme that repairs irregularities or breaks in the backbone of double-stranded DNA molecules. It has important role in the process of DNA replication and DNA repair. It has three general functions: It seals repairs in the DNA, it seals recombination fragments, and it connects Okazaki fragments (small DNA fragments formed during the replication of double-stranded DNA). DNA ligase functions by forming a bond between the end of a “donor” nucleotide and the end of an “acceptor” nucleotide.
Answer:
a. No discrepancy is present; organisms that contain an outer membrane and periplasmic space should stain pink because of their cell wall composition.
Explanation:
Gram stain is the staining method used to differentiate bacterial species into two groups, gram-positive and gram-negative bacteria. Factors that will differentiate gram-positive from gram-negative include the coloration of bacteria, the composition and chemical and physical properties of cell walls. In these tests, bacteria that have an outer membrane and a periplasmic space are considered gram negative and pink in color (sometimes similar to red) due to their cellular composition. For this reason we can state that there is no discrepancy present in the bacteria exposed in the question; Because this bacterium has an outer membrane and a periplasmic space, then it is normal for the bacteria to turn pink due to its cell wall composition.
The clear fluid in the acne after it has been squeezed is that it has the role of exudating. It is the mass of cells in forms of fluid and the role of it in the wound is to help the wound to heal and clean when the blood vessel open the area, and after the fluid has been exudated, the nutrients and the oxygen that is needed by the wound would be brought by the blood of the individual.
The tracing of uterine activity measured with a solid-tipped intrauterine pressure catheter (IUPC) depicts no contractions. However, you are palpating contractions that are strong in intensity with a frequency of every 3 minutes and a duration of 60 seconds. A possible cause for this finding is (select an answer): The connections to the system are not connected.
An IUPC counts the number, length, and force of contractions. During palpations peaks of strong intensity is recored.As in this case IUPC seems to be not connected as its near impossible to get no contractions when palpation are high.
And one unit is the amount of pressure required to raise a mercury column by one millimetre. The intensity of the contraction is assessed from the baseline (when the uterus is relaxed) to the rise of the contraction and is recorded in units. According to studies, after spontaneous labour, 200 units of contractions per 10 minutes are typically sufficient for vaginal birth.
