Answer:

A transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length,that serves as the physical link between the mRNA and the amino acid sequence of proteins. Transfer RNA does this by carrying an amino acid to the protein synthetic machinery of a cell (ribosome) as directed by the complementary recognition of a 3-nucleotide sequence (codon) in a messenger RNA (mRNA) by a 3-nucleotide sequence (anticodon) of the tRNA. As such, tRNAs are a necessary component of translation, the biological synthesis of new proteins in accordance with the genetic code.

Each mRNA molecule is simultaneously translated by many ribosomes, all reading the mRNA from 5′ to 3′ and synthesizing the polypeptide from the N terminus to the C terminus. The complete mRNA/poly-ribosome structure is called a polysome.

tRNAs in eukaryotes

The tRNA molecules are transcribed by RNA polymerase III. Depending on the species, 40 to 60 types of tRNAs exist in the cytoplasm. Specific tRNAs bind to codons on the mRNA template and add the corresponding amino acid to the polypeptide chain. (More accurately, the growing polypeptide chain is added to each new amino acid bound in by a tRNA.)

(More accurately, the growing polypeptide chain is added to each new amino acid brought in by a tRNA.) Therefore, tRNAs are the molecules that actually “translate” the language of RNA into the language of proteins.

Which of the following scenarios is representative of mutualism?
ycow [4]

<span>The correct answer is B. Bees pollinating flowers.</span>

<span>
In biology, mutualism is how two different organisms survive upon the activity of the other. Each benefits from the mutual relationship. In the case of bees pollinating flowers, both the bees and the flowers need something and benefit from the interaction with the other. </span>

Ivan

Answer:phytoplanktons are photosynthestic organism. They have the ability to produce their own food.

Explanation: Because of there small size they could absorb nutrients in the water even at lower concentration and convert it to energy need for there growth.

Its is said that phytoplanktons are one of the largest producer of oxygen gas.

Which climate conditions are typical of regions near the North Pole and the South Pole?
san4es73 [151]
Cold and extremely down climate is experienced in these locations, this is due to the lack of exposure to the sun's rays. The North and South Pole of the earth are also responsible for many meteorological and astronomical occurrences that protects earth and its inhabitants from the harsh exposure to the sun's rays.
