Answer: No

Explanation: if a nucleic acid contains uracil then it is not DNA it's an RNA. Uracil is the basic nitrogenous base of RNA. DNA does not have Uracil in its structure. It contains thiamine instead of Uracil. So the answer is NO.

3 lumps equals 1 clump and 10 clumps equals 1 pile, how many piles are 96 lumps
Lera25 [3.4K]

Answer:

3.2 piles

Explanation:

step 1

Find out the number of lumps in 10 clumps

we know that

3 lumps equals 1 clump

by proportion

Let

x ----> the number of lumps

\frac{3}{1} \frac{lumps}{clump}=\frac{x}{10} \frac{lumps}{clumps}\\\\x=10(3)\\\\x=30\ lumps

step 2

Find out how many piles are 96 lumps

we know that

10 clumps equals 1 pile

10 clumps equals 30 lumps

so

1 pile equals 30 lumps

using proportion

Let

x -----> the number of piles

\frac{1}{30}\frac{pile}{lumps}=\frac{x}{96}\frac{piles}{lumps} \\\\x=96/30\\\\x=3.2\ piles

Approximately what percentage of the human genome is composed of repetitive sequences?
Arturiano [62]
Approximately 50% of human genome is composed of repetitive sequences. It contains approximately 3 billion of these base pairs that reside with 23 pairs of chromosome within the nucleus or our cells or called nucleotides. Genes in the genomes of invertebrates such as Drosophila is not like the human genes because the human genes contain more and larger introns than the genes in the genomes. The human genes are larger than the genes in the genomes. The genome sequence is ~99.9% similar in individuals of all nationalities. Complete set of deoxyribonucleic acid of a single cell of an organism or sequence for humans (Homo sapiens) is called Genome. It includes both protein-coding deoxyribonucleic acid genes and noncoding deoxyribonucleic acid.
