Answer:
One
Explanation:
Sodium (Na) has one valence electron so it gets one dot.
The answer will be to: produce protein
Answer:
Part A It is associated with peroxisomes and mitochondria.
Part B. It is associated with smooth endoplasmatic reticulum.
Explanation:
The oxidation of long chain fatty acids are produced at the beginning in the mitochondria, it is called B oxidation because there is a carbon in this position that in this process is going to be oxidized to a carbonyl group. The very long fatty acid chains are also oxidized in the peroxisomes.
The cholesterol biosynthesis is made inside the hepatic cells, in the endoplasmatic reticulum. Is a process that starts with acetyl Coenzime A that was oxidized in the mitochondria. This process is regulated by the intake of cholesterol from the diet.

Answer: Promoter
Explanation:
Transcription is the first step in gene expression which consists of copying the DNA sequence of a gene to produce a RNA molecule. There are enzymes called <u>RNA polymerases which perform this process of transcription</u>. These enzymes bind nucleotides (the monomers which are part of the nucleic acids) to create a RNA strand using a DNA strand as a mold.
A promoter is a region of DNA that controls the initiation of transcription of a given portion of DNA to RNA. Therefore they promote the transcription of a gene. <u>The promoter region is composed of a specific sequence of DNA located just where the starting point of the DNA transcription is</u> and contains the information needed to activate or deactivate the gene it regulates. <u>The promoter has a binding site for the RNA polymerase enzyme </u>in charge of mRNA synthesis and when it recognizes this site, transcription begins.
