It helps in digestion of food

It enables growth and repair of tissues

It produces energy directly

It controls body temperature

Gene expression is a two step process of protein synthesis

Genes are unrelated to proteins, allowing them to change

The flow of information goes from DNA to RNA to Protein to RNA and out of the cell

Francis Crick explained the central dogma of not knowing why we have RNA

Transcription from DNA to RNA

Translation from RNA to Protein

Replication from DNA to DNA

Reverse transcription from RNA to DNA

Genes provide instructions for making proteins that aid in scab formation

Genes regulate blood flow to the wound area

Genes produce antibodies to fight off infection at the wound site

Genes control hormone production that influences scab formation

DNA is too large to pass through the nuclear membrane.

DNA is needed only in the nucleus.

DNA is unstable outside the nucleus.

DNA is not recognized by ribosomes.

tRNA brings amino acids to the ribosome.

DNA is transcribed to RNA.

Polypeptide chain folds into a protein.

RNA leaves the nucleus.
