Answer:

C. Fish first appeared when land plants evolved during the Carboniferous period

Explanation:

The age of fish was 410-360 million years ago which was called the Devonian period of the Paleozoic Era. This period immediately followed the Carboniferous Era which is 360-286 million years ago when amphibians dominate the land animals on the planet. Agnathans or jawless fishes are the first backboned fish. These fishes survived by sucking food in through the holes in their head.

how is translation initiated? view available hint(s)for part a hint 1for part a. how is translation initiated? the start codon s
Irina18 [472]

The Translation initiated is <u>Option D.All of the listed answers are correct. </u>

At the initiation of translation ribosomes and tRNA bind to the mRNA. tRNA is located at the first docking site of the ribosome. The anticodon of this tRNA is complementary to the start codon of the mRNA where translation begins. After binding to the mRNA, the ribosome initiates translation at the start codon AUG and moves the mRNA transcript one codon at a time until it reaches the stop codon.

When tRNA recognizes and binds to the corresponding codon in the ribosome, it transfers the corresponding amino acid to the end of the growing amino acid chain. tRNA and ribosomes then continue to decode the mRNA molecule until the entire sequence is translated into protein. tRNA acts as an adapter molecule during the translation process. Formerly known as soluble RNA or sRNA. As an adapter, it connects amino acids to nucleic acids.
