C. A wall of stones and mortar
This would act as a model describing the cell membrane.
Explanation;
A cell membrane is made up of a phospholipid bilayer with embedded proteins.
A cell membrane hold the different components of the cell together and to protect it from the environment outside the cell. It acts as a boundary between the inside environment and the outside environment of a cell.
It regulates the materials that enters and exits the cell; through selective movement of substances in and out of the cell.
1. Nucleus step1: DNA is transcribed into mRNA
2. Ribosome step2: mRNA is translated into protein
3. Endoplasmic Reticulum step 3: Newly synthesised proteins are transported.
4. Golgi apparatus Step 4: Proteins are modified then transported away
In Golgi body or apparatus, the proteins are modified, sorted and packaging occurs for secretion.
Only one strand will be transcribed and the other servers as a coding stand. ... Without it, the single strand DNA with exposed nitrogenous bases is very unstable so two strands actually stabilise the structure.
