Genes carry the information that determines your traits which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes.Chromosomes come in matching sets of two (or pairs) and there are hundreds — sometimes thousands — of genes in just one chromosome. The chromosomes and genes are made of DNA,
sickle cell anemia characteristics
blood cells are odd shaped and can not carry as much O2 as needed.
sickle cell symptoms
1. Difficulty breathing
2. Pale skin
3. Slow growth
4. Delayed puberty
8. Fast Heart Rate
An organism that has two different alleles for a trait
An organism that has two identical alleles for a trait
The sickle cell/malaria relationship demonstrates the concept in medical genetics that "disease" genes
different versions of a gene
compound with an amino group on one end and a carboxyl group on the other end
A technique of prenatal diagnosis in which amniotic fluid, obtained by aspiration from a needle inserted into the uterus, is analyzed to detect certain genetic and congenital defects in the fetus.
A sequence of three bases of a tRNA molecule that pairs with the complementary three-nucleotide codon of an mRNA molecule during protein synthesis.
Microscopic vessel through which exchanges take place between the blood and cells of the body
A genetic trait is considered dominant if it is expressed in a person who has only one copy of the gene associated with the trait.
in RNA processing, the coding sequence that remains in the final mRNA
Process in sexual reproduction in which male and female reproductive cells join to form a new cell
a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
process by which a gene produces its product and the product carries out its function
a technique that places a gene into a cell to correct a hereditary disease or to improve the genome
DNA segments that serve as the key functional units in hereditary transmission.
an experimental method of detecting and correcting defective genes in an individual
An organism's genetic makeup, or allele combinations.
An organism or cell having only one complete set of chromosomes.
iron-containing protein in red blood cells that carries oxygen for delivery to cells
Pair of chromosomes that are the same size, same appearance and same genes.
Cases in which one allele is not completely dominant over another
chorionic villus sampling (CVS)
A technique associated with prenatal diagnosis in which a small sample of the fetal portion of the placenta is removed for analysis to detect certain genetic and congenital defects in the fetus.
a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
A condition in which neither of two alleles of a gene is dominant or recessive.
A specific sequence of three adjacent bases on a strand of DNA or RNA that provides genetic code information for a particular amino acid
a collection of DNA sequences that tells Cas9 exactly where to cut
A noncoding, intervening sequence within a eukaryotic gene.
A disease caused by mosquitoes implanting parasites in the blood.
Cell division that produces reproductive cells in sexually reproducing organisms
a grid of DNA segments of known sequence that is used to test and map DNA fragments, antibodies, or proteins.
A type of RNA, synthesized from DNA, that attaches to ribosomes in the cytoplasm and specifies the primary structure of a protein.
three or more forms of a gene that code for a single trait
change in a DNA sequence that affects genetic information
each individual organism has unique characteristics that arise because of the differences in the nucleotide sequences found in the organism's DNA
the production, growth, and maturation of an egg, or ovum
A chart or "family tree" that tracks which members of a family have a particular trait
physical characteristics of an organism
trait controlled by two or more genes
Chains of amino acids
An allele that is masked when a dominant allele is present
site of protein synthesis
(genetics) an organism or cell having two sets of chromosomes or twice the haploid number
A complex molecule containing the genetic information that makes up the chromosomes.
Determining the exact order of the base pairs in a segment of DNA.
A single-stranded nucleic acid that passes along genetic messages
Modification of RNA before it leaves the nucleus, a process unique to eukaryotes.
sickle cell anemia
a genetic disorder that causes abnormal hemoglobin, resulting in some red blood cells assuming an abnormal sickle shape
A reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents
the production of sperm cells
(genetics) the organic process whereby the DNA sequence in a gene is copied into mRNA
(genetics) the process whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm
An RNA molecule that functions as an interpreter between nucleic acid and protein language by picking up specific amino acids and recognizing the appropriate codons in the mRNA
a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum.
