DNA Structure
The shape of a DNA molecule
double helix
the building blocks of proteins
amino acids
the purpose of mitosis
to divide a set of chromosomes into each daughter cell
the type of cells that are produced in meiosis
reproductive cells
the molecule produced during transcription
messenger RNA (mRNA)
the two men who first described the shape of the DNA molecule
Watson and Crick
the nucleotide base that replaces thymine in RNA
uracil
name the process in which a starfish uses mitosis to replace a missing arm
regeneration
name the gametes
egg cell and sperm cell
the product of translation
a protein
the four DNA base pairs
adenine-thymine
guanine-cytosine
the product of transcription
messenger RNA (mRNA)
the four stages of mitosis, in order
prophase, metaphase, anaphase, telophase
are the gametes haploid or diploid?
haploid
the product of replication
two identical DNA molecules
the product of replication
two identical DNA strands
the product of translation
a protein chain
the cell phase that occurs after mitosis
cytokinesis
the number of daughter cells produced by meiosis
4
the type of RNA that carries an amino acid to a ribosome
transfer RNA (tRNA)
name the kind of bases in DNA
nucleotide bases
matching pairs of chromosomes in a diploid cell
homologous chromosomes
the fibers that form in a cell and pull the chromosomes to opposite ends of the cell
spindle
a fertilized egg cell
zygote
the set of three nucleotides that code for an amino acid
codon
