<span>Ribonucleic acid (RNA) occurs
primarily as single strands, often giving rise to single polynucleotide
structures. RNA is a polymeric molecule
that is responsible for the regulation, coding, decoding and expression of
genes. Each nucleotide has a ribose sugar attached to the carbon, a base that
is composed of purines and pyrimidines, a negatively charge phosphate groups
and a hydroxyl group which causes helix to mostly adopt the A-form geometry.</span>
Answer:
Eukaryotes
Explanation:
The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus.
Answer:
Adenine= 22%
Guanine= 28%
Cytosine = 28%
Explanation:
According to Chargaff rule, the amount of adenine in a double-stranded DNA is equal to the amount of thymine. This is due to the fact that adenine and thymine bases are complementary and form base pairs.
Likewise, the amount of guanine in a double-stranded DNA is equal to the amount of cytosine since guanine pairs with cytosine.
Given that percentage of thymine in a DNA sample = 22%
Percentage of adenine = 22%
Total percentage of adenine and thymine = 22+ 22 = 44%
Percentage total of guanine and cytosine bases = 100-44 = 56%
Percentage of guanine base in the DNA = 56 /2 = 28%
Percentage of cytosine base in the DNA = 28%
