Answer: It stops getting amino acids when rRNA reaches the termination codon.

Explanation: During initiation stage of translation, the tRNA starts getting amino acids when the rRNA encounters the start codon, AUG. Like translation is terminated when the stop or termination codon is reached. There are three stop codons: UGA, UAA and UAG. These codons do not code for any amino acids.

Which of these statements best explains why the inner core of Earth does not melt although it has very high temperatures?

Ber [7]

Answer:

The core is in a cube structure, extreme temperatures make the atoms to move so quickly that there is no alteration of the structure hence, no melting.

Explanation:

In the case of extremely high temperatures, atoms change position but still keep their original shape.

Further explanation:

In the case of high temperatures, the atoms making up a cube move rapidly and change position, the change of position is the melting.

The process of converting the "message" of mrna into a sequence of amino acids is called:

olganol [36]

This process is known as translation

The process begins with messenger RNA (mRNA) giving instructions to amino acids. These instructions are sent with the help of transfer RNA (tRNA).

The amino acids form a chain called a polypeptide (proteins are made up of one or more polypeptide chains)

I have attached an image that will help your understanding of translation

I hope this helps! I'm happy to help with any other questions you might have :)
