Novosadov [1.4K]

I. treating the substance with nucleases that destroy all nucleic acids and then determining whether it is still infectious

Explanation:

Analysis of the nature of the specimen like the infectious agents (bacterium, virus, viriod, or prion) is very important to diagnose the diseases caused by them, investigate disease outbreak, to determine the clinical course of the infectious disease etc.

There are many methods like direct detection, cultivation assays, serological assays to detect the pathogen type.  

Molecular techniques like polymerase chain reaction (PCR) is done to further analyze or investigate the pathogen, like its microbial genome, the virulence factor etc. These are amplification methods which help to investigate the pathogenesis and disease progression. PCR method involves denaturing the DNA polymerase which is a nuclease type of enzyme. Nucleases are present with exonucleases and endonucleases, both of which acts at specific points on the DNA of the pathogen and will create new templates .

Do all genes have a simple dominant/recessive relationship between two alleles? What is an example of a human trait that does ha
luda_lava [24]

Answer:

Genes come in different versions, otherwise known as alleles, with dominant alleles being expressed over recessive alleles (one stronger than the other in terms of traits and etc). Recessive alleles are only expressed when no dominant allele is present. Color of the eyes, for example is allele A is brown color eyes and B is blue color eyes, and assume that A is the dominant then that relationship will prove A to be the simple dominant and B the recessive.

Answer:

Chloroplast

Explanation:

Fungi organisims are complete eukaurions, either it is plury or unicelular, it will allways have a definited nucleus, Golgi apparatus, reticulum, vesicles, and other. Generally, they have mitochondrions as machinary to get ATP; but some lesser, and specific fungis like thoses in the order Microsporidian, lost them through evolution.

Either way, a fungi does not have chloroplast, being an chemeotroffic organism, it have to adquire carbon and nitrogen sources from others.
