Across
1
system of nucleotide triplets in DNA and RNA that carries genetic information
3
biopolymers are antiparallel if they run parallel to each other but with opposite alignments. An example is the two complementary strands of a DNA double helix, which run in opposite directions alongside each other
5
threadlike, gene-carrying structure found in the nucleus
11
double-stranded, helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell's proteins
12
Body
14
Process of making a copy of DNA
15
Any cell in a multicellular organism except a sperm or egg cell
16
Enzyme
17
small protein with a high proportion of positively charged amino acids that binds to the negatively charged DNA and plays a key role in its chromatin structure.
18
self-regenerating cells in the marrow of long bones that give rise, by differentiation and division, to red blood cells and all of the different types of white blood cells
Down
1
unit of hereditary information consisting of a specific nucleotide sequence in DNA
2
specific pairing of the nucleotide bases linked by a hydrogen bond on opposite strands of DNA or double-stranded RNA: guanine is the complementary base of cytosine, and adenine is the complementary base of thymine in DNA and of uracil in RNA
4
The form of native DNA, referring to its two adjacent polynucleotide strands wound into a spiral shape
6
polymer consisting of many nucleotide monomers; serves as a blueprint for proteins and, through the actions of proteins, for all cellular activities. The two types are DNA and RNA.
7
organic base that contains the element nitrogen, includes adenine, guanine, cytosine, thymine and uracil (RNA)
8
essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied
9
Against
10
enzyme that synthesizes short RNA sequences called primers, which serve as starting points for DNA synthesis
13
building block of a nucleic acid, consisting of a five-carbon sugar covalently bonded to a nitrogenous base and a phosphate group
