To answer Question 3, we need to understand the relationship between DNA and mRNA codons. The mRNA codon is produced through a process known as transcription, where a specific section of DNA is copied to produce a complementary sequence of RNA. In this case, we are given that the mRNA codon for serine is AGU.

To find the base sequence of the DNA gene that originally produced this mRNA codon, we need to determine the complementary DNA sequence. The complementary base pairing rule states that adenine (A) pairs with thymine (T) in DNA and with uracil (U) in RNA, while cytosine (C) pairs with guanine (G).

Since we know that AGU is the mRNA codon, we can determine the complementary DNA sequence by swapping thymine (T) for adenine (A), uracil (U) for thymine (T), and guanine (G) for cytosine (C). Therefore, the base sequence of the DNA gene that originally produced this mRNA codon is TCA.

So the correct answer is TCA.

To answer Question 4, we need to evaluate the given statements to determine which one is true.

Statement 1: Thymine is only present in DNA, while cytosine is only present in RNA.
This statement is incorrect. Thymine is indeed only found in DNA, but cytosine is present in both DNA and RNA.

Statement 2: DNA and RNA are both double-stranded.
This statement is incorrect. DNA is typically double-stranded, consisting of two complementary strands, while RNA is usually single-stranded.

Statement 3: DNA has the sugar deoxyribose, while RNA has the sugar ribose.
This statement is correct. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose.

Statement 4: Translation copies DNA to mRNA, while transcription converts mRNA into proteins.
This statement is incorrect. Transcription is the process of copying DNA to produce RNA, specifically mRNA. Translation, on the other hand, is the process by which mRNA is used as a template to synthesize proteins.

Therefore, the correct statement is that DNA has the sugar deoxyribose, while RNA has the sugar ribose.
