Which is a strand of DNA and which is a strand of RNA...?

Question

Take a look at the strands below. Determine which is a strand of DNA and which is a strand of RNA.

CAGACGAAU

GCTACGGTA

Answer 1

DNA is made up of these 4 nucleotides:
A-Adenine ; T-Thymine ; G-Guanine ; C-Cytosine
Adenine pairs with Thymine, and Guanine with Cytosine

RNA is made up of the same nucleotides as DNA, but Thymine is replaced by U-Uracil.

:)

Answer 2

The first one, CAGACGAAU, is RNA and the second GCTACGGTA, is DNA. This is because DNA contains the bases T, C, G, and A and RNA contains U, C, G and A. Uracil replaces Thymine in RNA.

Answer 3

DNA is a molecule, comprised of nucleotides, the monomers of DNA. Each nucleotide contains a phosphate group, a five-carbon sugar, and a nitrogen base. The five-carbon sugar in DNA is called deoxyribose. Each nucleotide will contain one of four n-bases: guanine, adenine, cytosine, and thymine. Guanine and Adenine are called purines, while cytosine and thymine are pyrimidines. In the structural formula for purines, there are two rings made up of nitrogen and in the pyrimidines, there is one ring made up of nitrogen.

A major difference between DNA and RNA is that DNA contains thymine, but not uracil, while RNA contains uracil but not thymine. The other three heterocyclic amines, adenine, guanine, and cytosine are found in both DNA and RNA. For convenience, you may remember, the list of heterocyclic amines in DNA by the words: The Amazing Gene Code (TAGC).



CAGACGAAU - is an RNA strand

GCTACGGTA - is a DNA strand

Answer 5

the strand with the u in it is the strand that belongs to RNA. And the strans that doesn't has the u in it is the DNA one.

Answer 6

Uracil substitues for Thymine in RNA, so the first one is the RNA.

Answer 7

DNA stand for deoxinuclicacid RNA stand for ribose nucli acid
