a.
b.
c.

1. where is dna always found?
2. where is rna found?
3. how are the jobs of dna and rna different?
4. using the base pairing rule used in dna can you infer what the base pair rules will

b e in rna?

Explanation:

1. DNA is a nucleic acid that stores genetic information; its full name is a standard biological term.
2. RNA is a nucleic acid involved in expressing genetic information; its full name is a standard biological term.
3. Structural differences between DNA and RNA relate to sugar, strand structure, and nitrogenous bases.
4. DNA's primary location is the nucleus in eukaryotes, with small amounts in mitochondria/chloroplasts.
5. RNA is synthesized in the nucleus and functions in the cytoplasm.
6. DNA stores genetic code, while RNA executes code for protein synthesis.
7. RNA uses uracil instead of thymine, so base pairing adjusts from DNA's rules.

Answer:

1. Deoxyribonucleic Acid
2. Ribonucleic Acid
3. a. DNA has deoxyribose sugar; RNA has ribose sugar

b. DNA is double-stranded; RNA is single-stranded
c. DNA contains thymine; RNA contains uracil

1. In eukaryotic cells, DNA is always found primarily in the cell nucleus (small amounts in mitochondria and chloroplasts; in prokaryotes, it is in the nucleoid region).
2. RNA is found in the cell nucleus (during synthesis) and the cytoplasm (during function).
3. DNA's main job is to store and transmit genetic information long-term, while RNA's main jobs are to carry genetic instructions from DNA to ribosomes, assist in protein synthesis, and perform regulatory roles.
4. In RNA, adenine (A) pairs with uracil (U) instead of thymine (T), and cytosine (C) still pairs with guanine (G); when RNA pairs with a DNA template, A (DNA) pairs with U (RNA), T (DNA) pairs with A (RNA), C (DNA) pairs with G (RNA), and G (DNA) pairs with C (RNA).
