DNA molecules in the nucleas of the cell - Coggle Diagram
DNA
molecules in the nucleas of the cell
polynucleotides
2 = double helix
1 = helix
nucleotides
bases
cytosine
thymine
adenine
guanine
phosphate
sugar
types
template
coding
together they are connected by hydrogen bonds
chromosomes
DNA and proteins are condensed into this
have over 1000 genes
ploidy
number of chromosomes in cells
diploids
humans have 46
single
chromosomes
gametes (sex cells)
haploids
23 pairs of chromosomes
body cells
homologous pairs where each single chromosomes are replicated containing same genes, same location
paternal - from father
maternal - from mother
genes
sequence of DNA
make proteins
genetic code
each codes for specific proteins
amino acids are made up of proteins
polypeptides are made of amino acids
order is based off bases in DNA
genes code for different characteristics call alleles
growth
is through cell division
DNA is replicated before cell division
mitosis
replaces worn out cells or growth
produce two identical cells
process of mitosis
i prefer milk and tea
interphase
prophase
metaphase
anaphase
telophase
mutations
can change sequences of bases and alters structure of polypeptides, they are spontaneous
substitution
deletion
insertion
reproduction
sexual
fusion of female and male sex cells (gametes)
meiosis reduce number of chromosomes in a sex cells (female egg, male sperm)
asexual
without the fusion of male and female sex cells (bacteria)
