Answer:
The roots pulled up the food coloring with the water and it was transported through the xylem to the petals.
Explanation:
the xylem is one of the transport tissues in plants. It transfers water and nutrient from roots to stems and leaves.
First fill in the blank: Restriction enzymes (restriction endonucleases)
Second fill in the blank: Restriction sites
Trophic levels are the steps in between which the transfer and loss of energy occur.
Answer:
The correct answer is - transcription.
Explanation:
Transcription is the process that takes place in the nucleus and the final result of the process is an mRNA molecule that encodes the information of a specific DNA sequence.
Transcription in prokaryotes is carried out in three stages.
Initiation: Here, RNA polymerase binds to the promoter region and transiently binds to the ‘initiation factor’ to initiate transcription.
Elongation: This is the step where the RNA strand starts getting longer. RNA polymerase “walks” along one strand of DNA. For every nucleotide recognized on the DNA template, it adds a complementary RNA nucleotide to the growing RNA transcript.
Termination: Transcription stops once the RNA polymerase reaches the terminator region. At this region, the RNA transcript and the RNA polymerase, both fall off. RNA polymerase transiently associates with the ‘termination factor’ to stop transcription.
