Chapter 9: DNA - CW

Crossword for Chapter 9 DNA

QuestionAnswer
Adenine A nitrogenous base found in both DNA and RNA, abbreviated as A.
Base In molecular genetics, one of the nitrogen-containing, single- or double- ringed structures that distinguish one nucleotide form another. In DNA, the bases are adenine, guanine, cytosine, and thymine
Chromosome A single double helix together with proteins that help organize DNA
Complimentary base pair In nucleic acids, bases that pair by hydrogen bonding. In DNA, adenine is complimentary to thymine and guanine is complimentary to cytosine.
Cytosine A nitrogenous base found in both DNA and RNA, abbreviated as C.
DNA double helicase An enzyme that helps unwind the DNA double helix during DNA replication
DNA ligase An enzyme that joins the sugar and phosphates in DNA strand to create a continuous sugar-phosphate backbone
DNA polymerase An enzyme that bonds DNA nucleotides together into a continuous strand, using a preexisting DNA as a template
Replication The copying of the double stranded DNA molecule producing two identical DNA double helices
base that pairs with thymine in DNA Adenine
letter that symbols for purine bases in DNA AG
complimentary base sequence for TTAG AATC
enzyme that connects the nucleotides in a newly made DNA strand Ligase
type of nitrogenous base with two rings of atoms Purine
DNA replication is ______-conservative Semi
letter symbols for pyrimidine bases in DNA TC
DNA has a double-______ 3-D structure Helix
complimentary base sequence for CAATG GTTAC
type of nucleic acid with ribose sugar RNA
what genes are made of DNA
number of sizes of nitrogenous bases in nucleic acids Two
new strands of DNA are made using this enzyme Polymerase
smallest unit of life Cell
base that pairs with guanine in DNA Cytosine
co-discoverer of the double helix DNA structure Watson
has a phosphate group, a sugar, and a nitrogenous base Nucleotide
the opposite complementary base pair to TA AT
type of nitrogenous base with one ring of atoms Pyrimidine
an example is adenine Base
the enzyme that unwinds DNA during replication Helicase
cell structure in nucleus containing genetic material Chromosome
base that pairs with cytosine in DNA Guanine
number of different bases in a DNA molecule Four
co-discoverer of the double helix DNA structure Crick
number of types of sugar molecules in DNA One
a molecule of DNA is _____ stranded Double
DNA contains four types of _____ Bases
sugars found in DNA have _____ carbons each Five
DNA is found in cellular ______ Chromosomes
DNA contains sugars, bases, and _____ groups Phosphorus
purine bases are _____molecules than pyrimidine bases Larger
the concentration of DNA is ______ for different body cells of the same species Constant
adenine pairs with _____ in DNA Thymine
the duplication of DNA is called _____-conservative replication Semi
the building blocks of nucleic acids are _____ Nucleotides
purine bases A and G
pyrimidine bases C and T
base pairs in DNA A-T and G-C
single ring bases C and T
double ring bases A and G
If amounts of bases in a DNA molecule are measured, we find... T=A and G=C
when comparing DNA and RNA, we find Adenine pairs with different bases in DNA and RNA
the DNA of a certain organism has guanine as 30% of its bases. What percentage of its bases would be adenine? 20%
the correct structure of a nucleotide is Phosphate-ribose-adenine
the two polynucleotide chains in a DNA molecule are attracted to each other by hydrogen bonds between bases
using an analogy of DNA as a twisted ladder, the rungs (steps) of the ladder are Paired nitrogenous bases
all the cells of a specific organism contain equal amounts of Guanine and cytosine
the sequence of subunits in the DNA backbone is phosphate--sugar--phosphate--sugar
a pyrimidine base always base pairs with a Double ring purine
