Not sure if I did part A right, but I need help with the other questions.
Thanks!!

Great job on part A! The mRNA nucleotide sequence you provided is correct. Now let's move on to the other parts of the question.

1B. Indicate the product of this DNA segment/gene:
To determine the product of this DNA segment or gene, we need to translate the mRNA sequence into an amino acid sequence using the genetic code.

The genetic code is a set of rules that allows the conversion of a nucleotide sequence (in this case, mRNA) into an amino acid sequence.

To determine the product, we need to group the mRNA sequence into codons, each consisting of three nucleotides. Here's how we can do that for the given mRNA sequence:

AGC CGA UGU UUG UUU AGU UGC CCC GAG CGU UUG UUU AUU UGC

Next, we need to reference a genetic code table. The genetic code table provides the corresponding amino acid for each possible codon. Let's use the universal genetic code table for translation.

Using the genetic code table, we can determine the amino acid corresponding to each codon and string them together to form the product or primary structure of the gene.

1C. What is the product’s primary structure:
Using the genetic code table, let's translate each codon into the corresponding amino acid:

AGC - Serine (Ser)
CGA - Arginine (Arg)
UGU - Cysteine (Cys)
UUG - Leucine (Leu)
UUU - Phenylalanine (Phe)
AGU - Serine (Ser)
UGC - Cysteine (Cys)
CCC - Proline (Pro)
GAG - Glutamic Acid (Glu)
CGU - Arginine (Arg)
UUG - Leucine (Leu)
UUU - Phenylalanine (Phe)
AUU - Isoleucine (Ile)
UGC - Cysteine (Cys)

Combining these amino acids, we get the primary structure of the product as:

Ser-Arg-Cys-Leu-Phe-Ser-Cys-Pro-Glu-Arg-Leu-Phe-Ile-Cys

1D. How many peptide bonds are in the product:
To determine the number of peptide bonds in the product, we need to count the number of amino acid residues and subtract one.

In the primary structure of the product, we have a total of 13 amino acids. Since each peptide bond is formed between two amino acids, we need to subtract one from the total number of amino acids to get the number of peptide bonds.

Therefore, the product has 12 peptide bonds.

I hope this helps! Let me know if you have any further questions.
