mRNA
rRNA
tRNA

carries instructions for protein synthesis from the nucleus to the cytoplasm
carries amino acids to the ribosome and mtches them to the coded mRNA message
forms an important part of the ribosome

1

Genes contain the instructions for assembling

1

Inherited traits are:

1

Gregor Mendel observed that pea plant traits did not blend in their offspring. This led him to conclude that:

1

Artificial selection can occur naturally without human intervention.

1

Artificial selection can only be used to improve the physical appearance of an organism, not its behavior or ability to survive.

1

Artificial selection is often used by farmers, plant breeders, and animal breeders to produce organisms that are more productive, disease-resistant, or aesthetically pleasing. (aesthetically pleasing is another way to say "looks nice")
