Answer:
The following steps must be performed to make a bacterium produce human protein X: D) 6, 7, 2, 4, 5, 3, 1
Explanation:
To make a bacterium produce a human protein, it can be genetically modified in order to produce something useful, such as human inslun or human growth hormone. This is the right process in order to have a succesful result:
<em>1- Eukaryotic transcription; </em>
<em>2- Reverse transcription. </em>
<em>3- Restriction enzyme;</em>
<em>4-DNA ligase; </em>
<em>5-Transformation;</em>
<em>6-Prokaryotic transcription; </em>
<em>7-Translation; </em>
Answer:
D
Explanation:
Mitochondria in eukaryotes are believed to have evolved from a symbiotic relationship between protists and prokaryotes. It is proposed that maybe it evolved from protists engulfing prokaryotes as ‘food’. The evidence is due to the fact that mitochondria have their DNA that encodes for about 13 proteins used within the organelle. MtDNA is circular in shape which is very similar to the structure of prokaryotic DNA.
The correct answer among the options given is the last option. Fossil fuels are the resources that cannot be renewed. Resources that cannot be renewed or replenished are referred as non-renewable resources. Fossil fuels are made for very long periods of time and cannot be replenished instantly.
