Analyze the following statements. which of them is correct with respect to the rna transcript formed by means of transcription?
a. the rna transcript is an exact replica of the dna from which it is transcribed. it has the same sequence as that of its parent dna strand.
b. the rna transcript is complimentary to the dna from which it is transcribed. instead of thymine, it has uracil, which complements the adenine of dna.
c. the rna transcript is an exact replica of the dna from which it is transcribed. instead of adenine, it has uracil, which complements the thymine of dna.

Every compound can be represented by a chemical formula. a chemical formula is the set of symbols showing the elements that make up a compound and their proportions. water’s chemical formula is h 2 2 o. that means a molecule of water contains two atoms of hydrogen and one atom of oxygen chemically bonded. a molecule is a group of two or more atoms bonded together. molecules can range in size from two to thousands of atoms. a molecule of a compound is the smallest unit of that compound. every molecule of water has all the physical and chemical properties of water. that’s because every molecule of water is made of the same elements in the same proportions: two hydrogen atoms and one oxygen! which of the following is a true statement? a every molecule of the same compound will have different properties. b every molecule of a compound has the same proportion of elements. c molecules can be physically separated into smaller units of a compound. d molecules cannot be represented by chemical formulae.
