Vocabulary Terminology for Chapter 10 in Friendly Biology
Question or Term | Answer 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 |
