What structure brings tRNA and mRNA together
tester [92]
Translation requires some specialized equipment. Just as you wouldn't go to play tennis without your racket and ball, so a cell couldn't translate an mRNA into a protein without two pieces of molecular gear: ribosomes and tRNAs.<span>Ribosomes provide a structure in which translation can take place. They also catalyze the reaction that links amino acids to make a new protein.</span><span>tRNAs (transfer RNAs) carry amino acids to the ribosome. They act as "bridges," matching a codon in an mRNA with the amino acid it codes for.</span>Here, we’ll take a closer look at ribosomes and tRNAs. If you're not yet familiar with RNA (which stands for ribonucleic acid), I highly recommend checking out the nucleic acids section first so you can get the most out of this article!Ribosomes: Where the translation happensTranslation takes place inside structures called ribosomes, which are made of RNA and protein. Ribosomes organize translation and catalyze the reaction that joins amino acids to make a protein chain.

All the gametes of isogamous organisms are genetically identical.<br><br> True<br> False
Lady bird [3.3K]

Answer:

False

Explanation:

Gametes are formed by meiotic division, and classified by shape, size and activity. In some species they are undifferentiated, that is, isogamous, resembling, but not identical, regardless of gender. However, most species have heterogeneous gametes (anisogamy), differentiated by morphological, dimensional and mobility aspects.

Suppose a team of researchers becomes the first to synthesize organic molecules out of inorganic molecules. The conditions to wh
laila [671]

Answer:

Primitive Earth where life emerged was subjected to extreme conditions  

Explanation:

The origin of life is still an issue of intense debate today, although most researchers believe that life emerged from primitive organisms generated by the synthesis of organic compounds in early Earth. In line with this theory, it has been shown that membrane-forming compounds can be formed in extreme conditions (i.e., UV rays, extreme temperature, etc). It is believed that such conditions recreated in a laboratory were similar to the early Earth about 3,900 million years ago, thereby supporting the idea of the 'primordial soup theory' proposed by John Burdon Sanderson Haldane in 1929.
