One group of reptiles, characterized by the fossil Archaeopteryx, led to the evolution of birds. The correct answer is birds
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.
Ost proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes.
<span>As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.</span>
Answer:
mRNA
Explanation:
why because the process begins of transcription is
RNA polymerase
Brown because Bb or BB represents brown eyes while bb represents blue eyes
