interchanging of genetic material between nonhomologous chromosomes
Choose an answer
1 DNA molecule 2 polyploidy
3 frame shift mutation 4 translocation
Don't know?
Terms in this set (49)
double helix structure
DNA molecule
provides a code for all the body's proteins
adenine
DNA - 4 nitrogenous cytosine
bases guanine
thymine
, mutation any inherited alteration of genetic material
Base Pair substitution one base pair is replaced by another
mutation
insertion or deletion of one or more base pairs (not
frame shift mutation a multiple of 3) to the DNA molecule
can greatly alter the resulting amino acid sequence
ribonucleic acid
RNA uracil replaces thymine in the 4 bases
single strand
process by which RNA is synthesized from DNA
Transcription
forms mRNA
process by which RNA directs the synthesis of a
polypeptide
Translation the interaction of mRNA and tRNA, aided by
ribosomes, translate an amino acid to make a
growing polypeptide
thread-like structure contained in the nucleus of a
chromosome
cell; made of protein and one DNA molecule
all non-gametes (sex cells)
somatic cell 46 chromosomes in nucleus consisting of 23 pairs
mitosis for replication
sperm and egg cells
gametes 23 chromosomes
meiosis for replication
23 chromosomes - 22 pairs autosomes (not involved in gender)
consist of 1 pair = 2 sex chromosomes determining gender
cell has more than the diploid number of
polyploidy chromosomes
usually results in miscarriage
do not contain a multiple of 23 chromosomes
aneuploidy
usually result of nondisjunction
aneuploidy of an autosomal (non-sex) chromosome
autosomal aneuploidy containing 3 copies of chromosome = trisomy
containing 1 copy of chromosome = monosomy
