To absorb nutrients and help us grow and to get rid of harmful bacteria
Answer:
Nucleotides are the subunits of DNA. The four nucleotides are adenine, cytosine, guanine and thymine. Each of the four bases has three components, a phosphate group, a deoxyribose sugar and a nitrogen-containing base.
Answer:
Background
During the course of a bacterial infection, the rapid identification of the causative agent(s) is necessary for the determination of effective treatment options. We have developed a method based on a modified broad-range PCR and an oligonucleotide microarray for the simultaneous detection and identification of 12 bacterial pathogens at the species level. The broad-range PCR primer mixture was designed using conserved regions of the bacterial topoisomerase genes gyrB and parE. The primer design allowed the use of a novel DNA amplification method, which produced labeled, single-stranded DNA suitable for microarray hybridization. The probes on the microarray were designed from the alignments of species- or genus-specific variable regions of the gyrB and parE genes flanked by the primers. We included mecA-specific primers and probes in the same assay to indicate the presence of methicillin resistance in the bacterial species. The feasibility of this assay in routine diagnostic testing was evaluated using 146 blood culture positive and 40 blood culture negative samples.

Results
Comparison of our results with those of a conventional culture-based method revealed a sensitivity of 96% (initial sensitivity of 82%) and specificity of 98%. Furthermore, only one cross-reaction was observed upon investigating 102 culture isolates from 70 untargeted bacteria. The total assay time was only three hours, including the time required for the DNA extraction, PCR and microarray steps in sequence.
Development is like if you go blind you will most likely develop a high sense of hearing
growth is you grow and get taller
so basically development you have to try and growth occurs mostly naturally
Answer:
Choose distinct parallel lines.
Explanation:
They represent two parallel lines. The slopes are going to be the same in each line . Put the x value on the opposite side of the equal sign.
y = - 5x + 3 The slope is - 5
10x + 2y = - 6 Subtract 10x from both sides
2y = - 10x - 6 Divide by 2
y = -10x/2 - 6/2
y =-5x - 3
That minus three is the problem. You have 2 different y intercepts. That means that you have 2 parallel lines.
