A. At the end of meiosis I each cell has twice the number of chromosomes as was in the original cell.
<span>Messenger RNA (mRNA) molecules are long strands of RNA nucleotides that directribosomes to make proteins. They travel from the nucleus to the ribosome. Ribosomal RNA (rRNA) molecules make up part of the ribosomes of the cell in the cytoplasm. Transfer RNA (tRNA) molecules transport amino acids to the ribosomes.</span>
The synthesis of diphenylacetylene from mesostilbene dibromide includes next reactions:
• Bromination of stilbene-it is the reaction of electrophilic adition and bromonium ion is formed as intermedier (meso compound is the product).
• Bimolecular elimination-strong base is used in this reaction (takes away the H) and pi bond is formed.
Answer:
The type of regulation of gene expression that would have the greatest chance of success is Posttranslational control (E).
Explanation:
The defect is found on the structure of the protein, this means that the process of formation of the protein and the codons responsible for each amino acid in the protein is in correct order, this set the transcriptional and translational process aside as being correct.
Therefore, the problem lies in the formation of secondary or tertiary structure of the protein which requires a good number of proteins also, wherein lies tha main problem in the cell membrane protein. Thus the regulation of the posttranslational process and correction of the proteins needed at this stage will give the best chance of success.
Answer:
Chlorine has 7 valence electrons in its outer shell and needs 1 more electron to get a complete octet. Chlorine will not donate any electrons but will take 1 electron.
Explanation:
