Friendly Bio. Ch 10

Vocabulary Terminology for Chapter 10 in Friendly Biology

Question or TermAnswer or Definition
For each daughter cell to have its own set of chromosomes, the chromosomes must duplicate themselves
Chromosome duplication is possible due to the function of enzymes which are to either lyse or "matchmake" the appropriate parts of the DNA
DNA is abbreviation for Deoxyribonucleic acid
The carbohydrate component of DNA is ribose sugar
The nucleotide portion consists of ribose sugar, phosphate group, & a pair of bases
The pair of bases make up what portion of the DNA ladder the rung
There are two groups of bases and they are purines & pyrimidines
The purines are adenine & guanine
The pyrimidines are cytosine & thymine
the bonds between the bases are weak bonds known as Hydrogen bonds
Adenine bonds only with thymine (--Memory aid-- Always Time for Creative Games)
Cytosine bonds only with guanine (--Memory aid-- Always Time for Creative Games)
Enzymes lyse or cut the hydrogen bonds exposing the base pair
Matchmaking enzymes bring in free floating nucleotides in the area joining them according to the matching rules
Eventually two new strands of DNa are formed and one strand is for each daughter cell
