Question

Which statement best describes how organisms use DNA and amino acids to synthesize protein?

1 Dna is transcribed into mRNA, which is translated by the ribosome to produce an amino acid chain.
2 DNA is translated into mRNA, which is transcribed by the ribosome to produce an amino acid chain
3 Amino acids are transcribed into mRNA, which is translated into the nucleus to produce a molecule of DNA.
4 Amino acids are translated into mRNA, which is transcribed in the nucleus to produce a molecule of DNA.

Answer 1

1 Dna is transcribed into mRNA, which is translated by the ribosome to produce an amino acid chain.

Step-by-step explanation:

The steps of the process are always from DNA to mRNA to amino acids. This is because DNA can't travel out of the nucleus. So, DNA must be converted to mRNA to travel out of the nucleus. Only mRNA can leave the nucleus. The m in mRNA stands for messenger, so think of mRNA as the messenger from DNA to amino acids. Then the mRNA must be converted to amino acids to produce a protein.

So, options 3 and 4 are eliminated.

The process of DNA to mRNA is called Transcription. The act of transcription is called transcribing.

The process of mRNA to amino acid is called translation. The act of translation is translating.

The only option that fits this category is option 1.
