The _____ are responsible for linking amino acids together.
liberstina [14]

The answer is ribosomes.

The ribosome is the molecular machine inside the cell that makes protein from amino acids in a process called translation. It binds to a messenger RNA (mRNA) and reads the information contained in the sequence of bases of the mRNA. 

Transfer RNAs (tRNAs) containing amino acids enter the ribosome in a special pocket or binding site, called the acceptor site (A site). Once correctly bound, the ribosome can add the amino acid  on the tRNA to the growing protein chain, linking each amino acid to another with pin point accuracy.

in pea plants, purple flowers (p) are dominant over white flowers (p). Show the cross between two heterozygous plants
Ostrovityanka [42]

Answer:

       <em>P      p</em>

<em>P</em>    PP   Pp

<em>p    </em>Pp    pp

PP=Homozygous purple

Pp= heterozygous purple

pp=homozygous White

Explanation:

I tried to type out the cross. The bold letters are the heterozygous  plants that you are crossing. and the normal letters are the offspring of the two heterozygous parents being crossed. Heterozygous means they are different alleles. Homosygous means the same alleles are present.

heterozygous= Pp

Homozygous= PP or pp

I hope this was the answer you were looking for!
