Question

level 3: identify the following characteristics as belonging to dna, rna, both or neither
_ double stranded __ single stranded ____ contains genes
____ coils into chromosomes __ a, u, g, c ____ ribose sugar
____ leaves the nucleus __ transcription ____ made of nucleotide

Explanation:

Step1: Analyze "Double stranded"

DNA is typically double - stranded, RNA is usually single - stranded. So "Double stranded" belongs to DNA (D).

Step2: Analyze "Single Stranded"

RNA is single - stranded, DNA is double - stranded. So "Single Stranded" belongs to RNA (R).

Step3: Analyze "Contains Genes"

Genes are segments of DNA, and RNA can also be involved in gene expression but the main carrier of genes is DNA. However, in a broad sense, both can be related, but more precisely, DNA contains genes. Wait, actually, DNA is the molecule that contains genes (the genetic information). But also, some RNA viruses have RNA as their genetic material. But in the context of cellular organisms, DNA contains genes. But maybe the answer here is Both? Wait, no. Genes are made of DNA, and RNA is a product of transcription of DNA. So "Contains Genes" is DNA (D)? Wait, maybe I made a mistake. Let's think again. DNA has genes, and in some cases, RNA can have genetic information (like in RNA viruses). But in the context of this question, probably DNA (D) or Both? Wait, the standard answer: DNA contains genes, and RNA does not carry genes in the same way (except for RNA viruses). So "Contains Genes" - D.

Step4: Analyze "Coils into chromosomes"

DNA coils into chromosomes during cell division (in eukaryotes). RNA does not coil into chromosomes. So "Coils into chromosomes" - D.

Step5: Analyze "A, U, G, C"

RNA has adenine (A), uracil (U), guanine (G), cytosine (C). DNA has A, T, G, C (thymine instead of uracil). So "A, U, G, C" - R.

Step6: Analyze "Ribose sugar"

RNA has ribose sugar, DNA has deoxyribose sugar. So "Ribose sugar" - R.

Step7: Analyze "Leaves the nucleus"

RNA is synthesized in the nucleus and then leaves the nucleus to go to the cytoplasm. DNA remains in the nucleus (in eukaryotes). So "Leaves the nucleus" - R.

Step8: Analyze "Transcription"

Transcription is the process of making RNA from DNA. So both? Wait, transcription produces RNA, and DNA is the template. But the process of transcription is related to RNA synthesis. Wait, the question is about the characteristic belonging to DNA, RNA, Both or Neither. Transcription is a process, not a characteristic of the molecule. Wait, maybe the question is about which molecule is involved. Transcription produces RNA, and DNA is the template. But the characteristic of the molecule? Maybe the answer is Both? No, the molecule RNA is produced during transcription, and DNA is the template. Maybe the answer is RNA? Wait, no. Let's think again. The question is about the characteristic of the molecule (DNA, RNA, Both, Neither). Transcription is a process, but if we consider which molecule is associated with transcription, RNA is the product, and DNA is the template. But maybe the answer is Both? Or RNA? Wait, maybe the intended answer is RNA (R) because transcription makes RNA.

Step9: Analyze "Made of nucleotide"

Both DNA and RNA are made of nucleotides. DNA is made of deoxyribonucleotides, RNA is made of ribonucleotides. So "Made of nucleotide" - B (Both).

Answer:

• Double stranded: D (DNA)
• Single Stranded: R (RNA)
• Contains Genes: D (DNA)
• Coils into chromosomes: D (DNA)
• A, U, G, C: R (RNA)
• Ribose sugar: R (RNA)
• Leaves the nucleus: R (RNA)
• Transcription: R (RNA) (Note: This is a bit of a stretch as transcription is a process, but likely the intended answer is R as RNA is produced)
• Made of nucleotide: B (Both)
