C. Carbon
Mercury is dangerous to humans
Carbon is the main element in organic compounds, so carbon is essential to life on Earth.
Answer:
13. both donor DNA and vector DNA are digested with the use of a restriction enzyme that produces sticky ends and then mixed in a test tube to allow the sticky ends of vector and donor DNA to bind to each other and form recombinant molecules.
14. Because all DNA fragments have the same amount of charge per mass, small fragments move through the gel faster than large ones.
15. Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells at one end of a gel, and an electric current is applied to pull them through the gel.
16. DNA is colorless, so adding tracking dyes to a sample helps you determine the rate of movement of different size protein molecules in the gel during electrophoresis.
17. (A)The function of Taq DNA polymerase in PCR reaction is to amplify the DNA for the production of multiple copies of it (B) Taq polymerase can only make DNA if it's given a primer, a short sequence of nucleotides that provides a starting point for DNA synthesis (C) Primers are the strands of DNA that serve as this initial foundation for the DNA replication process, and they are used to demarcate the segment of the DNA template to be amplified
Explanation:
The rest is in the picture
Answer:
Through a chemical process called "condensation". The addition of the two molecules typically proceeds in a step-wise fashion to the addition product, usually in equilibrium, and with loss of a water molecule.

<u>Stem cell </u>research has the potential to significantly impact the development of disease-modifying treatments for Parkinson’s disease with considerable progress made in creating dopamine-progressing cells.
Explanation:
Parkinson’s disease, a neurodegenerative disease, leads to reduction of dopamine (a neurochemical messenger which carries messages involving thinking and body movements to brain) in the body because the disease will target and kill dopamine-producing nerve cells (neurons). This leads to loss of movement and thinking abilities which are activated by dopamine.
Stem cells research is done to study about the prospects of stem cells in stem cell therapy for Parkinson’s patients as a viable source of new dopamine nerve cells. Research has been involved in growing stem cells to replace or regenerate dopamine-producing nerve cells by using embryonic stem cells or induced pluripotent stem cells as a treatment modality in Parkinson’s disease.
