Answer:
i believe it is phosphate
Explanation:
False, mass number is protons plus neutrons. not subtraction.
Initiation:
In the cytoplasm, protein synthesis is actually initiated by the AUG codon on mRNA. The AUG codon signals both the interaction of the ribosome with m-RNA and also the tRNA with the anticodons (UAC). The tRNA which initiates the protein synthesis has N-formyl-methionine attached. The formyl group is really formic acid converted to an amide using the -NH2 group on methionine (left most graphic)
The next step is for a second tRNA to approach the mRNA (codon - CCG). This is the code for proline. The anticodon of the proline tRNA which reads this is GGC. The final process is to start growing peptide chain by having amine of proline to bond to the carboxyl acid group of methinone (met) in order to elongate the peptide.
Answer: Lipids
Explanation: The ratio of saturated and unsaturated fatty acids (lipids) determines the fluidity in the membrane at cold temperature.
False
Muscles are only able to contract or relax. This is why they need complementary muscles. For example, the bicep can raise the forearm, but cannot lower it. For that, the tricep is needed.
