Answer:
Explanation:
Translation ends in a process that called ( termination) .
Termination happens when a stop codon in the mRNA (UAA , UAG , UGA ) enters the A site.
Stop codons are recognized by proteins called release factors,
which fit neatly into the P site (Though they aren't tRNAs ) .

Answer:
A. Blood would leak backwards through the damaged valves due to gravity, causing lower leg swelling.
Explanation:
The passage of blood is always in a single direction in the vein due to the presence of valves in the veins.
Any kind of vein injury or vein rupture, causes the valves in the veins to not function in an appropriate manner. The injury might result in inappropriate opening and closing of these valves. The inappropriate functioning of the valves causes the blood to flow backwards. This will eventually lead to blood pooling and putting more pressure on the lower leg veins. hence, there would be swelling in the lower legs.
Answer: A membrane protein is defined as a protein that has an attachment to or is associated with a cell membrane or a cell organelle.
If one has a protein,the following will indicate that the protein is a membrane protein.
- They compose of the same
20 amino acids as contained in soluble protein.
- Sometimes, membrane protein attach itself to lipid moieties in a covalent manner.
- Unless they are anchored,they always diffuse liberally in the membrane.
- They sometimes attached to carbohydrates moieties covalently.
Of about 3-4 days in most cases. With severe damage it can take up to 30.
