Complete Question:

A transmembrane receptor that functions at the cell membrane has an exoplasmic N-terminal sequence, a signal-anchor sequence, and a stop-transfer-anchor sequence. This protein was first inserted into the membrane where?

a) in the late endosome

b) in the Endoplasmic Reticulum

c) at the plasma membrane

d) in the cis- Golgi

Answer:

Option b) In the Endoplasmic Reticulum

Explanation:

A transmembrane receptor is a the amino acid chain of a transmembrane proteins.

The proteins is inserted into the Endoplasmic Reticulum through the process of translocation.

How to clone a gene?
Flauer [41]

Answer:

Cut open the plasmid and "paste" in the gene. This process relies on restriction enzymes (which cut DNA) and DNA ligase (which joins DNA).

Insert the plasmid into bacteria. Use antibiotic selection to identify the bacteria that took up the plasmid.

Grow up lots of plasmid-carrying bacteria and use them as "factories" to make the protein. Harvest the protein from the bacteria and purify it.

Which two body systems interact to expel the waste product carbon dioxide
Pani-rosa [81]

Answer:

excretory system  and circulatory system

Explanation:

Blood is  part of circulatory system and as it move through various organs it exchanges the gases i.e give oxygen to the cell and take carbon dioxide from them. After taking CO2, the  blood becomes impure and hence it passes through the kidney before going to the heart. Kidney is part of excretory system which removes carbon dioxide from blood and thus purifies it.
