Answer:

Genus is Staphylococcus and specie is aureus i.e Staphylococcus aureus

Explanation:

Oropharynx:

Oropharynx also known as throat. It includes the tongue from its base region, the tonsils, the pharynx walls and the soft palate.

Oropharyngeal microbiota:

Microbiota are communities of microorganisms which may be symbiotic, commensal  and pathogenic  The oropharyngeal microbiota contains many microorganisms as it is known to be the major reservoir of infection.

Coagulase test:

This test is the laboratory procedure used for detection of Staphylococcus aureus. Staphylococcus aureus produces coagulase enzyme which catalyses the conversion of soluble fibrinogen in plasma to insoluble fibrin.

What alternate form of genes do nucleic acids have that allows them to offer variability allele codon nucleotide chromosome
Y_Kistochka [10]

Answer:

The options to this question are:

A) allele

B) codon

C) nucleotide

D) chromosome

The answer is A) allele

Explanation:

RNA and DNA are the two nucleic acids in living organisms used for transferring and storing genetic information. Deoxyribonucleic acid (DNA) is the genetic material in living organisms that contains segment coding for useful products/proteins and transmits genetic information from one generation to another. These segments are called GENES.

However, genes contain an alternate form responsible for genetic variation in the traits coded for by them. These alternate or variant form of a gene is called ALLELE. In a diploid organism like human, each trait is encoded by genes which contain contrasting pair of alleles that allows variation for that particular trait i.e. two alleles for each gene. For example, height trait in humans are encoded by gene, which possess two alleles; one coding for short variety (t) and the other for tall variety (T).

LiRa [457]

Answer:

So the cells that enter Meosis 2 are the ones that are made in Meosis 1. These cells are haploid meaning they have just one chromosome from each homologue pair. Also In meiosis II, the sister chromatids separate, making haploid cells with non-duplicated chromosomes.

Describe how an organism has 2 sets of dna and the importance of homologous chromosomes
LenKa [72]
Most organisms are Diploid, and as a result, they will have received 2 copies of the chromosomes, or sets of chromosomes, from both their parents. This they will have 2 sets of Genes that will perform almost exact same process, except with different phenotypes.

These chromosomes need to be homologous, in order for new alleles and other genetic combinations to be made.
