<span>DNA contains the code for all an organism's protein. Since many of the organism's structures, processes, and growth depend on protein the DNA is central to the well being of all organisms. In eukaryotes, the DNA is locked up in the nucleus. The area of the cell where proteins are made is in the cytosol (ribosomes). In order for the protein to be made the DNA has to produce a copy of the blueprint m-RNA. This messenger RNA will take the code to the ribosome. The process by which m-RNA is made is called transcription. A-U, C-G base pairing rules. Once on the ribosome another RNA comes into play t-RNA. This is called transfer RNA. Here it will take an amino acid and place it in the correct order to produce the desired protein. This is called translation. It begins with a start co don AUG. and ends with a stop codon. The protein will then go to the Golgi apparatus and be formed into its final shape.

Answer:
SER, they are capable of synthesizing testosterone of Adrenocortical cells.
Explanation:
Adrenal smooth microsomal cells are enriched in smooth endoplasmic reticulum SER, membranes of which contain high levels of translocation apparatus and oligosaccharyltransferase complex proteins. STEROID-SECRETING CELLS are characterized by abundant smooth endoplasmic reticulum (SER). These cells synthesize cholesterol as a precursor for steroid hormones or take up this substrate from plasma lipoproteins. Many of the enzymes for sterol and steroid synthesis are localized in the smooth-surfaced endoplasmic reticulum. This organelle is particularly prominent in cells of the inner zones of the adrenal and fluctuates in amount and configuration in response to hormonal stimulation and sterol levels.
Answer:
C. It is active transport, and moves against the concentration gradient.
Explanation: Pinocytosis is an active transport in which the molecules move from a low to a more higher concentration gradient. During this process it requires energy to move molecules and the energy used is ATP.
The correct answer for question number 1 is A - eukaryotes are the name
for unicellular organisms that dominated earth up to the Precambrian
times.
The correct answer for question number 2 is C - the
greenhouse effect is related to the phenomenon of an increase in average
surface temperature known as global warming.
The correct
answer for question number 3 is D - the colourless and odourless gas
that is produced by the radioactive decay of Uranium-238 and is considered
to be a cancer-causing agent is Radon.
The correct answer for
question number 4 is B - Scientists can determine if oxygen existed in
Earth's Archean atmosphere by looking for oxidized iron in rocks.
Answer is c have a good day
