What are good questions to ask about genetics?
Questions to ask about genetic testing
- Can genetic testing tell me for sure whether or not I have the condition?
- Can genetic testing be used to learn who in my family will develop the condition?
- Why should I have genetic testing?
- Are there disadvantages to having genetic testing?
- How accurate is the genetic test?
What questions should I ask about DNA?
What is a “strand” of DNA?
How do you determine which chromosome is a gene on?
The chromosome on which the gene can be found. The first number or letter used to describe a gene’s location represents the chromosome. Chromosomes 1 through 22 (the autosomes) are designated by their chromosome number. The sex chromosomes are designated by X or Y.
What is the relationship between genes and chromosomes?
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person’s genes. Genes are contained in chromosomes, which are in the cell nucleus.
What are some questions about chromosomes?
A chromosome contains many genes.
- How much information is in our DNA? A lot!
- What are mutations?
- What is recombination?
- What does dominant vs recessive mean?
- How do scientists figure out what gene controls a trait?
- Why can’t genetic tests predict all diseases?
- Why don’t identical twins look the same?
What do I know about genetics?
Human genetics is a branch of biology that studies how human traits are determined and passed down among generations. Explore this exciting field to better understand how your genes help shape your traits and health.
What do I need to know about genetics?
Genetics Basics: Six Things You Should Know
- DNA: What Is It and What Does It Do?
- Diversity and Variation among Humans.
- Inheritance, Health, and Disease.
- Family History.
- Genetic Testing, Privacy, and Healthcare.
- Medical Genetics.
Do chromosomes contain genes?
Genes are made up of DNA. Each chromosome contains many genes.
How do you know where a gene starts and stops?
A gene begins with a codon for the amino acid methionine and ends with one of three stop codons. The codons between the start and stop signals code for the various amino acids of the gene product but do not include any of the three stop codons.
Where are genes found?
chromosomes
Genes are found on tiny spaghetti-like structures called chromosomes (say: KRO-moh-somes). And chromosomes are found inside cells. Your body is made of billions of cells. Cells are the very small units that make up all living things.
Does a genetic test tell my future?
The wealth of information available to researchers allows them to create a polygenic risk score based on the DNA test of a person. This can be used to predict a person’s chances of getting a disease, his or her traits and behaviour, and many other things about their future.
How genes are inherited?
Like chromosomes, genes also come in pairs. Each of your parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes you have. Genes that are passed on to you determine many of your traits, such as your hair color and skin color.
