Answer:
DNA is a molecule composed of two chains in form of a DOUBLE HELIX compose by ORGANIC NITROGEN CONTAINING BASE, PHOSPHATE GROUPS and PENTOSE.
Explanation:
Nucleic acids are found in all living cells. They are composed of strands made up of repeating units called nucleotides. Each nucleotide consists of
--> a five carbon sugar( PENTOSE)
--> a phosphate group
--> an organic nitrogen containing base: adenine, guanine, cytosine or thymine.
The two types of nucleic acids include:
--> Deoxyribonucleic acid ( DNA) and
--> Ribonucleic acid ( RNA)
Deoxyribonucleic acid ( DNA) is found in chromosomes located in the nucleus of cells.
STRUCTURE OF DNA
The DNA molecule consists of two strands that curve spirally to form a double helix structure. The strands are held together by hydrogen bonds between the base side arms. Each base on one strand will only pair with a specific base on the other strand: hence guanine will only pair with cytosine and adenine with thymine.
FUNCTIONS OF DNA
It stores the organism's hereditary traits and directs the day to day metabolic activities of each cell in the organism.
CT (Computerized Tomography) scan uses X-ray images with the aid of a computer to generate cross-sectional views of a patient's anatomy. An MRI (magnetic resonance imaging) on the other hand is a scan that uses magnetic fields and radio waves to produce a detailed image of the body’s soft tissues and bones. An disadvantage of CT scan technology is the radiation exposure. Correct answer: C The level of the radiation depends on the design of the scanner, the size of the patient, the anatomic volume scanned, the scanning protocol, the technique used, and the quality of the x-ray beam
Pangaea began to break up into smaller continents, during the Mesozoic Era.
2. Look for a layer of sediment that is full of iridium.
This layer would represent the asteroid that scientists think hit Earth. The layer is the boundary in rock layers between the Cretaceous and Tertiary Periods.
