Answer:
1 Dna is transcribed into mRNA, which is translated by the ribosome to produce an amino acid chain.
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.
Answer:
The electron transport system is located in the cell membrane in bacteria, while in eukaryotes it is located in the mitochondrial cristae
Explanation:
Endosymbiosis is the hypothesis that complex organelles ( chloroplast and mitochondria) within the cell came from other living organisms. That is, they originated because one cell ingested another cell. A proof of this is that these organelles have their own genome and their own transcription and translation system. Their genome is independent of the genome within the nucleus of the cell.
The genome of the mitochondria is specialized in the electron transport system. The ingestion of a cell (i.e. bacteria) with such genome could bring evolutionary advantages to the to the ingesting cell over other cells without the mitochondrial genome.
