I. Understanding DNA as a Chromosome5 Key Points
A. Found in the
NUCLEUS of the cell

B. Composed of 1 very large, compacted,
TIGHTLY COILED strand of DNA
1. DNA name: DEOXYRIBOSE NUCLEIC ACID• Contains the HEREDITARY INFORMATION
for the assembly of PROTEINS in the body that specifies cell structure and function

I. Understanding DNA as a Chromosome5 Key Points
2. Built by repeating subunits or monomers
called NUCLEOTIDES: 3 parts
a. DEOXYRIBOSE SUGAR
b. PHOSPHATE GROUP
c. NITROGEN BASES (A,T,C,G)

3. GENE: a segment of DNA coding for a specific trait

C. Chromosome appearance in the cell varies
1. LOOSELY coiled: dark mass
2. TIGHTLY coiled: extended threadlike strands Can be seen during stages
of cell division

D. Chromosome number - Humans
Chromosome # in Humans
HAPLOID = 23 Chromosomes-1/2 set of chromosomes-Gamete: sex cells-ex: sperm and egg
Diploid = 46 Chromosomes-Full set of chromosomes-Somatic Cell: body cellsEx: skin, liver, zygote

E. Chromosomes have the ability to
REPLICATE or COPY ITSELF Once DNA copies itself, it will contain an
identical half
