The codon AUG specifies the amino acid methionine. What would the tRNA anitcodon be that recognizes this codon?
NemiM [27]

Answer:

UAC

Explanation:

This example portrays that translation, which is the second process of protein synthesis, is about to occur. Translation cannot occur without a special type of RNA called tRNA or transfer RNA.

A tRNA contains a set of three nucleotides called ANTICODON. The tRNA matches an mRNA codon with the amino acid it encodes. The tRNA initially binds to the mRNA and reads the mRNA codon using its anticodon (which is complementary to the mRNA's codon). The actual reading is done by matching the base pairs through hydrogen bonding following the base pairing rule i.e. A-U, G-C. After reading the mRNA codon using its anticodon, it then carries the specific amino acid encoded by that codon it binds to, in order to add to the growing polypeptide chain.

For example, a codon AUG (start codon that signals beginning of translation) will be read by tRNA anticodon, UAC. Since the codon AUG codes for amino acid, Methionine. The tRNA then carries Methionine via its amino acid attachment site and adds to the polypeptide chain (future protein).

The two main types of fermentation are called
jok3333 [9.3K]
The two main types of fermentation are alcoholic fermentation and lactic acid fermentation. In an alcoholic fermentation, the main product of this process is ethyl alcohol. Lactic acid on the other hand has lactic acid as its main product. When muscle cells run out of oxygen, lactic acid fermentation would commonly take place.<span> </span>

Which is not an impact to the ecosystem after a drought?
Nadya [2.5K]

Answer:

A. Floods will wipe out all the vegetation

Explanation:

Drought is an environmental condition characterized by scarcity of water. Less rainfall and reduced ground water levels facilitate drought like conditions. In the event of drought, animals face difficulty in finding food and water and thus are forced to migrate to other areas. However, flood is exact opposite to drought. It is caused by excess rainfall or increase in water level which destroys the ecosystem. It is not a characteristic of drought.
