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

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.

The amino acid chain of the transmembrane protein has an exoplasmic N-terminal sequence, a signal-anchor sequence which is hydrophobic alpha helix and a stop-transfer-anchor sequence which consists of a 22-25 hydrophobic amino acid sequence.

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
