Answer:I think During most of a cell's life cycle, DNA, along with proteins, is a mass of loose strands called chromatin (KROH-muh-tin). Before cell divion, DNA is duplicated, or copied. Then, in an early stage of cell division, the chromatin is compacted into visible structures called chromosomes (KROH-muh-sohmz).Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.During interphase, the cell obtains nutrients, and duplicates (copies) its chromatids (genetic material). The genetic material or chromatids are located in the nucleus of the cell and are made of the molecule DNA. hope this helps have a nice night ❤️❤️❤️
Explanation:
Answer:
Koch's postulates say that microbes are present in the case of every disease and these disease-causing microbes can be isolated to grow in pure culture. He also said that this pure culture if transferred in healthy individual it will cause disease.
Chytrids contain many parasite fungus that infects amphibians and by using Koch postulate we can show that chytrid infections are responsible for the frog deaths.
First, we have to take the sample from dead diseased amphibian then this sample should be inoculated in a selective media which supports the growth of chytrid fungus and not bacteria.
Then this pure culture of fungus is transferred in a healthy amphibian. The death from chytrid infection of healthy amphibian will show that chytrid infections are responsible for the frog deaths.
Answer:
The answer is the VPg Protein.
Explanation:
The question is incomplete, here is the full question:
Poliovirus is a positive-sense RNA virus of the picornavirus group. At its 5' end, the RNA genome has a viral protein (VPg) instead of a 5' cap. This is followed by a nontranslated leader sequence, and then a single long protein coding region (~7,000 nucleotides), followed by a poly-A tail. Observations were made that used radioactive amino acid analogues. Short period use of the radioactive amino acids result in labeling of only very long proteins, while longer periods of labeling result in several different short polypeptides.
What part of the poliovirus would first interact with host cell ribosomes to mediate translation?
A) the poly-A tail
B) the leader sequence
C) the VPg protein
The part of the host cell ribosome that the poliovirus would interact first is the VPg protein because the poliovirus has to affect the RNA to be able to replicate it's own DNA and the VPg protein is attached to the RNA's 5' end.
I hope this helps.

Answer:
<u>Several processes move carbon from the </u><u>geosphere</u><u> to the </u><u>atmosphere</u><u>. Volcanic eruptions release carbon dioxide from molten rock beneath the earth's surface. The production of cement that's used for homes, skyscrapers, streets and other hardscapes around the world releases an enormous amount of carbon dioxide.</u>
