What are the 2 common part of a nucleotide?
Nucleotide A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base uracil (U) takes the place of thymine.
How are RNA and DNA similar how do they differ quizlet?
RNA is different from DNA is three ways: (1) the sugar in RNA is ribose not dioxyribose; (2) RNA is generally single-stranded and not double-stranded; and (3) RNA contains uracil in place of thymine. Because they make it easier for enzymes in the cell to tell DNA and RNA apart.
How does RNA and DNA work together?
Cells make RNA messages in a process similar to the replication of DNA. The DNA strands are pulled apart in the location of the gene to be transcribed, and enzymes create the messenger RNA from the sequence of DNA bases using the base pairing rules. 3. RNA molecules made in a cell are used in a variety of ways.
What are the subunits of DNA and their function group of answer choices?
1 Answer. Nucleotides are the subunits of DNA, they form the genetic code.
What is the percentage of bases in DNA?
The sum of all four percentages must equal 100%. We know that the sample is 22% adenine; this tells us it is also 22% thymine. Since cytosine and guanine are present in equal amounts, we can simply divide their sum by 2. The final composition is 22% adenine, 22% thymine, 28% cytosine, and 28% guanine.
What is the percentage of cytosine in yeast?
An organism such as φX174 with significant variation from A/T and G/C equal to one, is indicative of single stranded DNA….Percentages of bases in DNA.
|A / T||0.95|
