If the sequence of bases on the mrna codon is auu what would be the sequence of bases on the trna anticodon
Klio2033 [76]

Answer:

uaa

Explanation:

An anticodon is a trinucleotide sequence localized in the transport RNA (tRNA) that binds via complementary base pairing to the codon in the messenger RNA (mRNA) during protein synthesis (translation). Thus, the tRNA anticodon binds with its complementary three-letter mRNA codon during translation in order to add a specific amino acid to the growing protein. Generally, the anticodon sequence positions 34–36-nt of the tRNA that reads its cognate mRNA codon sequence via Watson–Crick base pairing.

Colchicine is a toxin that binds to tubulin proteins and prevents microtubules from elongating. What effect might this have on d
lianna [129]

The effect Colchicine might have on dividing cells is that the duplicated chromosomes might not be able to segregate into daughter nuclei.

Colchicine is an alkaloid that attaches to tubulin and prevents it from polymerization to microtubules. As we know that Microtubules are a component of the cytoskeleton of a cell that aids in molecular mobility inside the cell.

During cell division, chromatin condenses into chromosomes, which are then connected to microtubules. The chromosomes are separated into daughter cells by microtubules.

When these cells are treated with colchicine, tubulin polymerization to microtubules may not occur, and the chromosomes containing daughter nucleic might not be separated.

Select a drug to research. Explain how tolerance and withdrawal would work for a person addicted to that drug.

Withdrawal: Symptoms a person experiences when not using a substance, due to the body reacting to no longer having the substance. Now back to the alcohol… alcohol is a very commonly used on types of drugs, for an example like regular rubbing a alcohol, drinking and more. This type can really make somebody addicted to the type of substance that is in it. Hope this helps!

What are the use of Land?​
frutty [35]

Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods. Land use by humans has a long history, first emerging more than 10 thousand years ago. It has been defined as "the purposes and activities through which people interact with land and terrestrial ecosystems and as "the total of arrangements, activities, and inputs that people undertake in a certain land type. Land use is one of the most important drivers of global environmental change.
