1. Write the letter of the dominant allele.
Answer:
B, T
Explanation:
Dominant alleles are represented with an UPPERCASE letter. Recessive alleles are represented with a LOWERCASE letter
The letter of the dominant allele represents the uppercase version of the corresponding gene. In genetics, alleles are different forms or variations of a gene that occupy the same position or locus on a chromosome. Each gene has two alleles, one inherited from each parent.
When determining the letter of the dominant allele, it is important to consider the dominant-recessive relationship between the alleles. The dominant allele is the allele that is expressed or seen in the phenotype when present, even if there is only one copy of it. It masks the expression of the recessive allele.
For example, in the case of eye color, let's say the gene for brown eye color (B) is dominant over the gene for blue eye color (b). If an individual inherits one allele for brown eyes (B) from one parent and one allele for blue eyes (b) from the other parent, their genotype would be Bb. However, since the brown eye color allele (B) is dominant, the individual's phenotype would be brown eyes.
In this case, the letter of the dominant allele is B. It represents the dominant gene for brown eye color.

What kind of plants live in the desert?
Answer:
Cacti and Succulents, Wildflowers, and Trees, Shrubs, and Grasses.
Answer:
Plants that usually live in the desert have ways to collect and store water for long periods of time, and have little to no leaves. They might have a specific kind of root or a different way of storing water than other plants. I hope this answer is helpful :)
Explanation:
Why choose that gene for PCR in the bacterial identification lab?
It is highly variable so will show slight differences between distantly related species
It is just what everyone else does, the actual gene doesn't matter, just the sequence comparison.
The primers are easy to obtain for it.
it is highly conserved so will show slight differences between distantly related species
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.
Explanation:
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.
