Answer:
<em>The correct options are:</em>
<em>Prior to process 1, DNA should copy itself to allow the cell to divide.</em>
<em>Between processes 1 and 2, the mRNA must be modified before leaving the nucleus.</em>
Explanation:
For eukaryotes, the mRNA is made in the nucleus from the DNA. This process in known as transcription. The process of making proteins from the mRNA takes place in the ribososmes of the cytoplasm. This process is known as translation. The mRNA has to be modified before it is transported for translation. Otherwise, the mRNA will be degraded by the enzymes of the nucleus.
Answer:
The correct answer is : temporal isolation.
Explanation:
Temporal isolation is a one type of prezygotic reproductive isolation in which the the prevention of mating of the two species takes place due to the time difference of breeding, this could be day difference, season difference, or years difference.
Here in this example the reproductive isolation is taking place due to the difference in their mating time, where L. graminifolia flowers in the early spring and L. canadensis in different season of summer.
Thus, the correct answer is : temporal isolation.
Answer:
Most of the carbohydrates in the meals you consume are digested and crushed down inside glucose before accessing the bloodstream. Glucose in the blood is used up within your body's cells and applied to provide a fuel molecule called adenosine triphosphate (ATP) through a sequence of complex processes known as cellular respiration.
Explanation:
Answer and Explanation:
The steps for construction of the expression plasma
- STEP 1 : Introducing Notl and Hindlll confinement sites at the ends of the gene of interest by means of PCR
- STEP 2 :Digest the plasmid and DNA encoding gene with the Notl and Hindol confinement endonucleuses.
- STEP 3 : Ligate the cut plasmid and DNA fragment
- STEP 4 : Change the plasmid into E.coli for expression
- STEP 5 : Clean the protein by utilizing a column of immobilized
Fertilization refers to the process of two gametes of opposite sex uniting (option C).
<h3>What is fertilization?</h3>
Fertilization is the process whereby the male gamete unites with the female gamete to form a zygote.
In sexually reproducing organisms, the male organism of a species produces a gamete called sperm cell while the female organism produces egg or ova.
Therefore, it can be said that fertilization refers to the process of two gametes of opposite sex (male and female) uniting.
