MMbio 240 Flashcards
Sequencing read
segmented fragments of the sequence
Sequencing assembly
process of sequencing
sequencing contig
overlapping clones in sequence
consensus sequence
sequence that has nucleotides that are most used (majority rule)
precision medicine
medicine tailored to certain genes
diploid genome
2?
ortholog
2 species with similar gene
homolog
similarities within same species
paralog
similarities within cell
allele
one part of gene
synteny
genes are similar across different species
homologous chromosomes
2 chromosomes that are same
sister chromatids
make up chromosome
genomics
comparison of DNA sequences
better understand genetic composition and genetic relationships or evolution
transcriptomics
comparisons of RNA (transcriptomes)
proteomics
comparisons of proteins
intron
portions of DNA that can be removed
exon
codable parts of DNA
splicing
splicing out introns
linkage analysis
seeing if a disease is attached to a certain gene
duplication
duplicating a nucleotide
transposition
nucleotide gets moved to different part of gene
inversion
gene gets inverted in on itself
dot plot
can compare genes, see how closely related they are
genome map
phylogenetic tree
see how closely related organisms are
clade
group with common ancestor
branch
branch of phylogenetic tree
node
common ancestor
in group
clade all bunched together
outgroup
organism with most differences
motif
recurring sequence in genes
topology
use topoisomerase to cut DNA strands
telomere
end part of DNA
centromere
center of chromosome
kinetochore
place where spindles attach on the chromosome
telomerase
adds nucleotides to telomere
telomere repeat sequence
telomere repeats a lot. makes DNA polymerase unable to transcribe it
genomic packaging
histones do this
bacterial core proteins
kinda like histone proteins, DNA wraps around it
nucleoid
supercoil
coiled coiled DNA
mtDNA
mitochondrial DNA
histones
proteins that DNA wraps around. provide structural support for proteins
Topoisomerase
enzymes that create alterations in DNA
linkage sites (Lk)
topoisomer
NICK
small cut on gene
electrophoresis
relaxed DNA
chromosomal scaffold
residue after extraction of histones, mostly histones
linker DNA
SMC protein
promote chromosome condensation. creates contact between segments of DNA
HAT
transfers acetyl groups to histone tail
HDAC
removes acetyl groups from histone tails
