Answer:
Rosalind Franklin (Franklin)
Gene expression includes two major processes transcription and translation:
Transcription is the process in which RNA nucleotides find their complementary base on the DNA and are joined together to make a single-stranded RNA molecule.
DNA Base RNA Base
C G
G C
T A
A U
Translation - The RNA molecule, generated called messenger RNA or mRNA acts as a messenger to decide which amino acid needs to be added to the peptide chain
. The mRNA contains three-base sequences called codons, which tell the ribosome what specific amino acid needs to be added.

Answer:
1. a model
2. genetic drift or a bottleneck event
3. small population
4. random mating; assortative mating
5. random
6. change in allelic frequency due to mutation
7. small population
Explanation:
The Hardy-Weinberg model enables us to understand the distribution of genotype frequencies in a population that is not evolving, thereby being a key null model used in population genetics. Genetic drift is a genetic phenomenon where allele frequencies change in a population depending on chance events. A bottleneck event is a type of genetic drift caused by the decrease in the population size. The genetic drift is generally stronger in small populations because this genetic phenomenon produces more dramatic shifts in allele frequencies when populations are smaller. This same phenomenon is produced by the emergence of mutations in smaller populations. Random mating, also known as panmixia, is an ideal situation where individuals mate only by chance, and thus there is no sexual selection. Random mating is a condition that is required in Hardy Weinberg equilibrium. The absence of mutations is also a requirement of the Hardy Weinberg equilibrium (because it would lead to the origin of new alleles in the population). Assortative mating is a mating pattern where individuals with particular phenotypic traits mate more frequently than expected under a random mating model.
The DNA replication products visualized during the sanger method of DNA sequencing are observed in which nucleotides are added.
Sanger sequencing is based on the process of DNA replication. A scientist creates a copy of his DNA strand. Then observe which nucleotides have been added. This way you can see the sequence of nucleotides. A laser excites the fluorescent labels in each band and a computer detects the resulting light.
Sanger sequencing produces extension products of various lengths ending in dideoxynucleotides at the 3' ends. Extension products are separated by capillary electrophoresis or CE. Molecules are injected by an electric current into a long glass capillary filled with gel polymer. Selective incorporation of chain-terminating dideoxynucleotides by DNA polymerases during in vitro DNA replication.

The etiologic agent of the disease must be first identified. The most important thing to know is the source of the organism. Transmission of the disease must be identify to prevent further spread and limit the number of persons with the disease.The route,mode of transmission should be identified. Quarantine of those infected and symptomatic can be done if necessary. The initiation of treatment must be started once infection is identified. Prophylaxis can also given to those individual at risk of acquiring the disease.
