Question

rna is very similar to dna in all ways except for a few differences. first, where the sugar in dna is deoxyribose, the sugar in rna is ribose. second, where dna is a double helix, rna has just one strand. third, where the bases in dna are c,g, a and t, in rna the bases are c, g, a and u. the u in rna takes the place of the t in dna. fourth, dna cannot leave the nucleus of the cell and rna can. 46. list four differences between dna and rna. a. b. c. d. 47. list three similarities between dna and rna. a. b. c.

Explanation:

For question 46, DNA and RNA differ in sugar type (deoxyribose in DNA, ribose in RNA), number of strands (double - helix in DNA, single - strand in RNA), base composition (T in DNA, U in RNA), and location (DNA mainly in nucleus, RNA can leave nucleus). For question 47, both DNA and RNA are nucleic acids, contain phosphate groups, and have the bases A, C, and G.

Answer:

46.
a. Sugar type: Deoxyribose in DNA, ribose in RNA.
b. Number of strands: Double - helix in DNA, single - strand in RNA.
c. Base composition: T in DNA, U in RNA.
d. Location: DNA mainly in nucleus, RNA can leave nucleus.
47.
a. Both are nucleic acids.
b. Both contain phosphate groups.
c. Both have the bases A, C, and G.
