Answer:
<u>Both</u>:
- The start codon is often AUG
<u>Eukaryotic cell only:</u>
- The larger subunit of the ribosome is 60s.
- The ribosomes initially binds the 5' end of mRNA.
<u>Prokaryotic cell only</u>:
- The ribosome is 70s
- Translation occurs in the cytoplasm
- There are multiple ribosome binding site
Explanation:
- AUG is the common start codon for both eukaryotic as well prokaryotic cells. In eukaryotic cell, it codes for methionine . While in prokaryotic cell, it codes for formyl methionine.
- In prokaryotic cell, ribosomes are found in cytoplasm, hence the translation occurs in cytoplasm.
- Eukaryotic ribosome consists of two subunits; 40s and 60s(larger subunit)
- Prokaryotic ribosomes have 70s ribososme, which consists of 50s and 20s subuints
- in eukaryotic cell, 40s ribosome initially binds to the cap at the 5' end of mRNA.
- Bacterial mRNA contain multiple ribosome binding sites.
Answer:
B) fats
Explanation:
Common hepatic duct is s the part of the biliary tract which means that is involved in the secretion of bile.
Bile salts secreted from the bill have an important role in emulsification of lipids (fats). They have the ability to aggregate around lipids thanks to their amphipatic nature. Amphipatic nature means that they have hydrophobic side which binds directly to lipids and hydrophilic side which are faced outwards. Lipids enveloped with bile salts are called micelles.
Formation of micelles increases the surface area of fat, which is appropriate for the the action of the enzyme pancreatic lipase (perform digestion of triglycerides).
Answer: The cell membrane invaginates and pinches off, creating a vesicle within the cell.
Explanation:
Endocytosis is an active transport mechanism, for particules to be transported, the plasma membrane of the cell invaginates, forming a pocket around the target particle. The pocket then pinches off, resulting in the particle being contained in a newly created intracellular vesicle formed from the plasma membrane.
DRIs is the general term for a set of reference values or guidelines that are used to plan and asses nutrient intakes of healthy people. These values which vary by age and gender include:
- Recommended Dietary allowance (RDA): average daily level of intake sufficient to meet nutrient requirements of about 97 - 98% of healthy people.
-Adequate intake (AI): established when evidence is not sufficient to develop an RDA and is set at a level assumed to ensure nutritional adequacy.
- Tolerable Upper Intake (UL): Maximum daily intake unlikely to cause adverse health effects.
DRIs are not necessarily found on labels because there is no law requiring that they must be placed there.
