10. Where is RNA formed? To where does it travel?

11. What is the difference between mRNA and tRNA?

12. What are three bases of mRNA called? At what organelle are they read?

13. What is the purpose for mRNA?

Using the following strand, answer the questions that follow.

ACUUAAGCGCAUAUC

14. What type of molecule is this?

15. Show the original strand undergoing transcription.

16. Transcribe the amino acid chain that would be formed.

17. What macromolecule does this amino acid chain become?

A base pairs with T, G with C. In RNA, A pairs with U and G pairs with C. I think you just need to do some more readings... most of these can be answered in your book or note for sure.

8. RNA is formed inside the nucleus of a cell.

To determine the location of RNA formation, we can understand the process known as transcription. During transcription, DNA is converted into RNA by an enzyme called RNA polymerase. This process occurs in the nucleus of a cell because that is where the DNA is located.

9. In DNA, the base pairs are adenine (A) with thymine (T) and cytosine (C) with guanine (G). However, during transcription, RNA replaces thymine with uracil (U). Therefore, the pairings from DNA to RNA are adenine (A) with uracil (U) and cytosine (C) with guanine (G).

10. RNA is formed in the nucleus of the cell during transcription. After its formation, RNA travels from the nucleus to the cytoplasm, where it performs various functions depending on its type.

11. mRNA (messenger RNA) is responsible for carrying the genetic information from DNA in the nucleus to the ribosomes in the cytoplasm for protein synthesis. tRNA (transfer RNA) brings the corresponding amino acids to the ribosomes during translation.

In summary, the difference between mRNA and tRNA lies in their functions. mRNA carries genetic information whereas tRNA carries amino acids.

12. The three bases of mRNA are called codons. Codons consist of three nucleotide bases and each codon codes for a specific amino acid during translation. mRNA is read by ribosomes, which are organelles located in the cytoplasm of a cell.

13. The purpose of mRNA is to carry the genetic information from DNA to the ribosomes in order to synthesize proteins. By encoding the sequence of amino acids, mRNA acts as a template for protein synthesis.

Now let's move on to the given strand and answer the questions related to it:

14. The given strand ACUUAAGCGCAUAUC is an RNA molecule. We can determine this because RNA contains the base uracil (U) instead of thymine (T), which is found in DNA.

15. The original DNA strand can be derived by replacing each occurrence of uracil (U) with thymine (T) in the given RNA strand. Therefore, the original DNA strand undergoing transcription would be ACTTAAGCGCATATC.

16. To transcribe the amino acid chain from the given strand, we need to know the mRNA codon table (also known as the genetic code). By referring to this table, we can determine the amino acids coded by each codon. However, the given strand does not provide enough information to determine the codons, so we cannot accurately transcribe the amino acid chain.

17. Without knowing the specific codons from the given RNA strand, we cannot determine the macromolecule that the amino acid chain would become. The amino acid chain synthesized from mRNA would combine with other chains and undergo further modifications to form a functional protein.
