Why heart disease is not an infectious disease?<br><br><br> I need help please

Sidana [21]

Answer:

The old idea that coronary heart disease is an infectious disease has gained popularity in recent years, and both viral and bacterial pathogens have been proposed to be associated with the inflammatory changes seen in atherosclerosis. Herpes group viruses, notably cytomegalovirus and herpes simplex type 1, have been associated with atherosclerosis and restenosis. Helicobacter pylori and dental infections have also been linked to atherogenesis, but the evidence seems to favor a respiratory, obligatory intracellular bacterium, Chlamydia pneumoniae. The association was originally found in seroepidemiological studies, but the actual presence of the pathogen in atherosclerotic lesions has been repeatedly demonstrated, and during past year the first successful animal experiments and encouraging preliminary intervention studies were published. The causal relationship has not yet been proven, but ongoing large intervention trials and continuing research on pathogenetic mechanisms may lead to the use of antimicrobial agents in the treatment of coronary heart disease in the future.

In the central dogma, the rna-to-protein step is termed.

Zarrin [17]

Answer:

translation

Explanation:

a process called translation uses this mRNA as a template for protein assembly. In fact, this flow of information from DNA to RNA and finally to protein is considered the central dogma of genetics, and it is the starting point for understanding the function of the genetic information in DNA.

_____________ and __________ are the components of ribosomes.

Rainbow [258]

Answer: The correct answer is rRNA and protein.

Explanation:

Ribosome is a cell organelle present in the cytoplasm of all living cells. It is a site of protein synthesis in all type of cells. It is made up of two sub-units namely, small sub-unit and large sub-unit.

Both the sub-units are formed by rRNA (ribosomal RNA) and associated proteins. rRNA is ribozyme, that is, it is a ribonucleic acid with catalytic ability. The protein component helps in providing the structure to the ribosome.

what is the order of three genes (x, y, and z) that are located on the same chromosome, based on the following information? gene

Mekhanik [1.2K]

The recombination frequency between genes is useful to determine the distance between genes and their order in the chromosome. The correct order of genes in this chromosome is X-Z-Y.

<h3>What is the recombination frequency?</h3>

Recombination frequency refers to the probability of crossing-over events occurrence between two genes. There farther genes are from each other, the greater recombination frequency there will be.

Recombination frequencies are also used to determine the distance between genes, and if they are linked or not.

So, if we know the recombination frequencies, we can calculate the distances between the genes and figure the genes' order out.

The map unit is the distance between the pair of genes for which one of the 100 meiotic products results in a recombinant one.

1% of recombination frequency, RF = 1 Map Unit, MU = 1 centiMorgan, cM

Now let us analyze the data

Three genes ⇒ X, Y, Z.
Distance between X-Y = 17% = 17 MU
Distance between Y-Z = 9% = 9 MU
Distance between X-Z = 8% = 8 MU

When the RF is given, we already have the distance between genes.

Now, to put these genes in order, we need to look for the most distant genes. These are probably the ones placed at the extremes of the chromosomal fragment.

In this case, the most distant genes are X-Y. So,

---------X-----------------Y---------

17 MU

Then, we need to place the remaining genes, which are probably between the two extremes genes. To be sure of this position, the addition of these middle genes must equal the distance between the extreme genes.

In our example, we only have one remaining gene Z.

The distance from X to Z = 8 MU
The distance from Y to Z = 9 MU
9 MU + 8 MU = 17 MU which is the distance between X and Y (extreme genes)

-----------X-------------Z----------------------Y---------

║----8MU---║------- 9 MU -----║

║-------------17 MU ---------------║

So, according to this reasoning, the correct order of genes in this chromosome is X-Z-Y.
