Chromosome should be the correct answer
Answer:
An expression vector assists in expressing the gene into an mRNA and then into a protein by the process of transcription and translation respectively. In order to develop an effective expression vector, it should possess various essential organism-specific sequences so that they can articulate the desired gene.
For the process of transcription, a promoter is required, in order to understand the expression of a specific gene a selectable marker is required. While in prokaryotes, an RBS or the ribosome binding sequence like a Shine Dalgarno sequence is needed on the mRNA copy to initiate the process of translation.
Thus, it can be concluded that the researcher has missed out on the ribosome binding sequence due to which translation has not taken place.
Answer:
The Earth moon rotates in the same amount of time that it revolves.
Explanation:
The moon is the only Earth's natural satellite and it orbit round the Earth. It is the fifth largest natural satellites. It was formed not long after the formation of the Earth. The moon rotates on its axis . The moon rotate once and it's matches the period it's orbit making it to keep the same side facing of the Earth. This means that the moon the moon rotates once every time it revolves the Earth.
