Studied by 0 peopleGenome
The entire set of genetic information that an organism carries in its DNA
male
A(n) ________ with an extra X chromosome has Klinefelters syndrome.
Typhoid
________ is caused by a bacterium that enters the body through cells in the digestive system; the protein made by the CF allele helps block this bacterium from entering the cells.
Genotype
________ and phenotype are directly connected since changes in a genes DNA sequence can change proteins.
Females
________ have two copies of the X chromosome and males have one X chromosome and one Y chromosome.
circle
A(n) ________ or square that is not shaded indicates that a person does not express the trait.
Bioinformatics
________ also began a similar field of study known as genomics- the study of whole genomes including genes and their functions.
Cystic Fibrosis
________ is usually caused by the deletion of three bases in the DNA of a single gene, causing the body not to make normal CFTR (a protein needed to transport chloride ions)
Female cells
________ adjust to having two X chromosomes by randomly inactivating genes on one of them.
Pedigree
A chart that shows the presence or absence of a trait according to the relationships within a family across several generations
X chromosome
A cell only needs one ________ to function normally.
human genome
Two of the 46 chromosomes in the ________ are known as sex chromosomes because they determine an individuals sex.
inactive chromosome
The ________ makes a dense area in the nucleus called a Barr body.
Human Genome Project
The ________ was completed in 2003.
karyotype
A(n) ________ shows the complete diploid set of chromosomes.
X chromosome
A female who inherits only one ________ usually has Turners syndrome.
The Human Genome Project had two main goals
to sequence all 3 billion base pairs of human DNA and to identify all human genes
Karyotype
A photograph of the complete diploid set of chromosomes grouped together in pairs, arranged in order
Sex chromosomes
One of two chromosomes that determines an individual’s sex
Sex-linked gene
A gene located on a sex chromosome
Nondisjunction
An error in meiosis in which the homologous chromosomes fail to separate properly
Restriction enzyme
An enzyme that cuts DNA at a sequence of nucleotides
Gel electrophoresis
A procedure used to analyze DNA fragments by placing a mixture of DNA fragments at one end of a porous gel and applying an electrical voltage to the gel
Bioinformatics
The application of mathematics and computer science to store, retrieve, and analyze biological data
Genomics
The study of whole genomes, including genes and their functions
