Accepted Answer

### Question 6
# Explanation:
## Step1: Recall DNA base pairing rules
In DNA replication, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).
## Step2: Pair each base in the original strand
Original DNA strand: AAC CTA GCG TCG
- AAC: A pairs with T, A pairs with T, C pairs with G → TTG
- CTA: C pairs with G, T pairs with A, A pairs with T → GAT
- GCG: G pairs with C, C pairs with G, G pairs with C → CGC
- TCG: T pairs with A, C pairs with G, G pairs with C → AGC
Combine these: TTG GAT CGC AGC
# Answer: TTG GAT CGC AGC

### Question 7
# Brief Explanations:
The first step of protein synthesis is transcription, where DNA's genetic information is copied into mRNA. Transcription occurs in the nucleus of eukaryotic cells (or in the cytoplasm of prokaryotes, but typically taught as nucleus for basic biology).
# Answer:
a. First Step: Transcription
b. Where it occurs: Nucleus (of a eukaryotic cell)

### Question 8
# Brief Explanations:
- Option a: ATP is not transcribed from DNA; ATP is an energy molecule. Eliminate.
- Option b: Ribosomes do not transcribe DNA; transcription is done by RNA polymerase. Eliminate.
- Option c: mRNA is transcribed from DNA, not the other way. Eliminate.
- Option d: Transcription makes mRNA from DNA, and mRNA is used by ribosomes for translation (assembling amino acids into proteins). This matches the process.
# Answer: d. DNA genes are transcribed into mRNA. The genetic information in the mRNA is used by ribosomes to assemble amino acids into proteins.

### Question 9
# Explanation:
## Step1: Recall transcription base pairing rules
In transcription, DNA's A pairs with mRNA's U, T pairs with A, C pairs with G, G pairs with C.
## Step2: Pair each base in the DNA strand
DNA strand: GTT ACG CAG TAT
- GTT: G→C, T→A, T→A → CAA
- ACG: A→U, C→G, G→C → UGC
- CAG: C→G, A→U, G→C → GUC
- TAT: T→A, A→U, T→A → AUA
Combine these: CAA UGC GUC AUA
# Answer: CAA UGC GUC AUA

### Question 10
# Explanation:
## Step1: Apply transcription base pairing rules
DNA strand: GCA TCT AGC CCG
- GCA: G→C, C→G, A→U → CGU
- TCT: T→A, C→G, T→A → AGA
- AGC: A→U, G→C, C→G → UCG
- CCG: C→G, C→G, G→C → GGC
Combine these: CGU AGA UCG GGC
# Answer: CGU AGA UCG GGC

### Question 11
# Brief Explanations:
- Option a: If B involves forming proteins from amino acid codons, that is translation (ribosomes use mRNA codons to assemble amino acids). This matches translation.
- Option b: Transcription is DNA→mRNA, not protein synthesis from DNA. Eliminate.
- Option c: mRNA is single - stranded, and transcription is DNA→mRNA (A would be transcription only if it's DNA→mRNA, but the description of double - stranded mRNA is incorrect). Eliminate.
- Option d: Translation is not DNA replication, and mRNA is single - stranded. Eliminate.
# Answer: a. B is translation because proteins are being formed from amino acid codons.
