Only answer no explanation to save time. 1 to 5
spin [16.1K]

Step 1. mRNA is transcribed in the nucleus, exits to the cytosol through, and binds to a ribosome.

Step 2. Protein synthesis occurs at the rough endoplasmic reticulum.

Step 3. The protein travels by vesicle from one organelle to another inside the cell.

Step 4. The Golgi apparatus processes, sorts, and tags the protein for delivery to its final destination.

Step 5. Exocytosis.

What did Mendel's cross pollination of pea plants prove
pashok25 [27]

Answer: The correct answer is- D certain factors are dominant and other factors are recessive.

Mendel was interested in knowing the offspring that is produced from the cross pollination (that is from two different plants) as he wanted to study different traits of pea plant.

For doing so, he first removed the anthers of one plant (to prevent self pollination) and then transferred the pollens of one plant into the stigma of another plant.

When he allowed the cross pollination of purebred pea plant with other plant, he observed that some factors are dominant (such as tall height of pea plant, which masks the expression of recessive factors) and other are recessive (such as dwarf height of pea plant).

Thus, option D) is the right answer.

You add the following components (in the correct volumes and concentrations) to a tube to perform a PCR reaction Buffer Magnesiu
uranmaximum [27]

Answer:

b. False

Explanation:

These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.

The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.

For a PCR reaction to be performed a solution with some components must be prepared. These components are:

  • Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
  • Forward and reverse primers (to customize the start of the enzyme reaction)
  • DNA polymerase (Enzyme required for replication of desired DNA region.)
  • DNA Template (the DNA to be copied)
  • PCR-grade water
  • Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).

Explain four treatment options for hazardous waste.
marusya05 [52]

Chemical methods--It includes ion exchange, precipitation, oxidation and reduction, and neutralization.........

Thermal methods--In this, high-temperature incineration, which not only can detoxify certain organic wastes but also can destroy them....

Biological treatment-- It is of certain organic wastes, such as those from the petroleum industry by a special method called landfarming

Physical treatment-- It concentrates, solidifies, or reduces the volume of the waste. Physical processes include evaporation, sedimentation, flotation, and filtration....
