25
What contains the nucleoid?
Cytosol
26
Region where the prokaryotic cells’ DNA resides =
Nucleoid
27
How many chromosomes does most bacteria have?
Just 1
28
Unlike eukaryotes, bacteria have-
Circular chromosomes (usually 1 per cell)
29
Because of bacteria genome structure, bacteria are considered to be-
Haploid Cells
30
Bacterial chromosome is located in the-
Nucleoid
31
How long is DNA compared to the cell?
DNA is several times longer than the cell
32
How does DNA fit inside the cell?
Supercoiling compacts DNA so that the whole genome fits inside the cell
33
Eukaryotes have what kind of chromosomes?
Nuclear Chromosomes
34
Eukaryotes typically have how many chromosomes per cell?
More than 1
35
Nuclear chromosomes are-
Linear + Sequestered within the nucleus
36
Eukaryotic cells are often-
Diploid
37
2 Chromosome Copies =
Diploid
38
Globular proteins that aid in condensing DNA so it fits in the nucleus =
Histones
39
DNA stands for-
Deoxyribonucleic Acid
40
RNA stands for-
Ribonucleic Acid
41
The monomers/ building blocks of genetic material =
Nucleotides
42
How many types of nucleotides?
2 DNA + RNA
43
Nucleic acids are polymers of-
Nucleotides
44
Each nucleotide is made up of how many parts?
3
45
The 3 parts of nucleotides =
Phosphate Group Pentose Sugar (5 Carbons) Nitrogenous Base
46
Length of DNA is expressed in-
Base Pairs
47
Nucleotides with a one ring structure =
Pyramidines
48
Pyrimidine Examples=
Cytosine Thymine (DNA Only) Uracil (RNA Only)
49
Nucleotides with a two ring structure =
Adenine Guanine
50
The sides of the DNA molecule are held together by special chemical bonds called-
Phosphodiester Bonds
51
A pairs with -
T
52
C pairs with -
G
53
In RNA, Thymine (T) pairs with Uracil (U), so
U pairs with A in RNA specifically
54
3 hydrogen (h) bonds between -
C and G
55
2 h bonds between -
A and T / A and U
56
A base with 3 h bonds won’t interact with -
A base with only 2 h bonds
57
A base with 3 possible hydrogen bonds will not interact with a base that only has 2 possible hydrogen bonds. This ensures that-
The correct bases always interact with one another
58
10 bases per turn of-
The DNA double helix
59
Major Grooves=
Wide space between the backbone
60
Minor Grooves =
Narrow space between the backbone
61
2 strands of DNA run in opposite directions and create-
Minor + Major Grooves
62
What kind’ve grooves have an abundant space for enzymes to interact with DNA?
Major Grooves
63
DNA that isn’t a part of the chromosomes =
Extrachromosol DNA
64
For eukaryotic cells extrachromosomal DNA is usually what kind of DNA?
Mitochondrial or Chloroplast DNA
65
For prokaryotic cells and some lower eukaryotes like algae, fungi and protozoa, extrachromosomal DNA can be-
Plasmid DNA
66
What are some types of plasmids?
