DNA is made up of deoxyribose sugar while mRNa is made up of ribose sugar. DNA has thymine as one of the two pyrimidines while mRNA has uracil as its pyrimidines base. DNA is present in the nucleus while mRNA diffuses into the cytoplasm after synthesis. DNA is double stranded while mRNA is single stranded.
Hope this is helped ;)

Answer;
Organisms capture energy from the environment.
Explanation;
-Organisms Capture & Store Free Energy for Use in Biological Processes.
Autotrophs capture free energy from physical sources in the environment.
-Photosynthetic organisms capture free energy present in sunlight.
-Chemosynthetic organisms capture free energy from small inorganic molecules present in their environment, and this process can occur in the absence of oxygen.
Heterotrophs capture free energy present in carbon compounds produced by other organisms.
-Heterotrophs may metabolize carbohydrates, lipids, and proteins by hydrolysis as sources of free energy.
-Fermentation produces organic molecules, including alcohol and lactic acid, and occurs in the absence of oxygen.
Answer:
The mixture of nucleotides required for this procedure is called dNTPs.
Explanation:
When the polymerase is used in a PCR procedure, to replicate a molecule or DNA fragment, use a combination of nucleotides called dNTPs.
DNTPs are nothing less than DNA nucleotides, applied as reagents in a PCR solution, which provide the material necessary for the polymerase to replicate DNA, even outside a biological system.
Answer:
These are the following precautions that must be taken during the blood borne Pathogens and Other Potentially Infectious Materials:
- The area that are exposed with the pathogens must be washed with the water and soap. The exposure source must be notified to the lab assistant or supervisor.
- The unprotected sex must be avoided to prevent the transmission of the pathogen from mother to the fetus.
- The finger or the area must be rubbed with the alcohol and must be involved in the daily routine of the hand hygiene.
- The individual should not eat or apply anything on the wounded area exposed with the pathogens.
- Some blood borne pathogens are hepatitis B virus, bacteria and some pathogens as well.
