If we were to observe a cell in prophase and see 3 centromeres, how many chromatids are present?
Answer:
The correct answer is - 6 chromatids.
Explanation:
Prophase is the stage in the cell cycle that is known for the condensation and disappearance of the nucleolus. In this stage chromosome become more compacts and the sister chromatids are still together and not separated. These sister chromatids are joined together with the centromere.
Centromere do not allow sister chromatids to move away and makes it intact. The number of centromere is the number of chromosme present in the prophase and half of the sister chromatids that means if there us 3 centromere than the number of sister chromatids will be 6.

This model shows the process of protein synthesis including transcription and translation. What is the best explanation for what is
occurring at the arrow (translation)?
Answer: The answer is C
Explanation:
During the process of protein synthesis, the best explanation for what is occurring at the arrow is as follows:
The codon on the mRNA pairs with the anticodon on the tRNA which transfers amino acids into the proper sequence to form a protein.What is Protein synthesis?Protein synthesis may be defined as a biological process through which cells make proteins in order to accomplish metabolic functions that facilitate the survival of living organisms. The process of protein synthesis terminates with the help of two stages. They are as follows:
Transcription.Translation.Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. While the process of translation acquired the transfer of genetic instructions from the mRNA to the sequence of amino acids in order to form proteins. This takes place in the cytoplasm of the cell.

Which of the following is NOT a common element in the human body? Select all that apply.
Answer:
Helium and carbon dioxide
The elements that are not common in human body are carbon dioxide and helium. The correct options are B and E.
What are elements?A chemical element is a type of atom with a specific number of protons in its nucleus, including the pure substance made up entirely of that species.
Chemical elements, unlike chemical compounds, cannot be broken down into simpler substances by any chemical reaction.
The human body is made up of only six components: oxygen, hydrogen, nitrogen, carbon, calcium, as well as phosphorus.
Sulfur, potassium, sodium, chlorine, and magnesium make up about 0.85% of the remaining mass. All 11 of these elements are necessary.
Carbon dioxide and helium are elements that are not found in the human body.
Thus, the correct options are B and E.

B. Band A and band B contain the same DNA fragments.
C. Band A moved faster than band B.
D. The DNA in B is more positively charged than the DNA in A.
Answer:
D. The DNA in B is more positively charged than the DNA in A.
D. The DNA in B is more positively charged than the DNA in A.
Explanation:
The DNA in band B is relatively smaller than that of the DNA in band A. Option A is correct.
DNA Electrophoresis:It is a technique that is used to separate DNA fragments of different sizes. In this technique, agarose gel is used as the base.DNA moves from the negative electrode towards the positive electrode. Large DNA molecules run slower than smaller DNA molecules because small molecules easily pass through the pores of the agarose gel.Therefore, the DNA in band B is relatively smaller than that of the DNA in band A.
