TERMINOLOGY Flashcards
(23 cards)
GENE
- sections of DNA arranged along chromosome
- order of the bases make genetic code
DNA
-deoxyribose nucleic acid
- characteristics of an organisms
- carries genetic info
NEUCLEOTIDE
-molecules that contain (A,C,T,G) in DNA
- basic structural unit of DNA
CHROMOSOMES
- thread like structure of nucleic acid in nucleus
BASE PAIR
a pairing of bases adenine and thymine, cytosine and guanine
A,C,T,G
-order of bases along DNA strand
AUTOSOMES
- chromosomes that don’t define sex
heterozygous
2 different alleles for characteristics
homozygous
2 alleles that are identical
chromatid
one of the 2 identical halves of the chromosomes
mutation
change in DNA sequence
fertelization
egg and sperm combining
gamete
a mature reproductive cells
genetic
study of inherited characteristics (traits)
heredity
sub parts of genetics and passing of characteristics to offspring
meosis
cell division that results in sexual reproducing an organism that reduces the number of chromosomes in cells
sexual reproduction
production of new organisms by the combination of gene info of 2 individuals from different sexes
diploid cell
cell with 2 full sets of chromosomes
haploid cell
single set of chromsones
DNA REPLICATION
when DNA makes a copy of it self during cell division
MITOSIS
when parent cell divides to make new daughter cells
asexual reproduction
reproduction of new cells by division of the parent cell into 2 daughter cells
DNA, CHROMOSONE AND GENE RELATIONSHIP
In the nucleus is chromosome. Chromosomes carry DNA in cell. Genes are segments in DNA.
