<u>Answer:</u>

<em>If Mendel crossed a true breeding dominant plant with a true breeding recessive plant the recessive trait is visible in the F3 generation. </em>

<u>Explanation:</u>

In <em>Mendel’s cross the selected parents are a tall pea plant and a short pea plant.</em> Tall is the dominant trait and short is the recessive trait.  Both the parents are homozygous.

Letter T represents tall and t represents short. Hence the phenotype TT is homozygous dominant and tt is homozygous recessive.  

<em>The genotype Tt represents tall since T is dominant over t. Mendel’s cross can be represented as  </em>

<em>Tall \times Short</em>

<em>TT \times tt</em>

<em>F1 generation      Tt     Tt   Tt   Tt </em>

<em>F2 generation     TT   Tt  Tt tt   </em>

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.
