This test will be used to determine the origin of organic meat as it is prohibited to label meat as organic if derived from double muscled cattle. The divisor is the number where we divided our numbers. Returns refers to the resulting number after it has actually been split. Combining and divising numbers to create a brand-new number is an arithmetic operation. The division procedure is straightforward. Experimentally, this will be achieved by amplifying the STRs using PCR and analyzing the PCR product size using gel electrophoresis.Īfter identifying the gene responsible for double muscling, your last task will be to develop a DNA test. Dna Mutation Simulation Worksheet Answer Key. By detecting STR patterns and similar gene sequences in double muscled cattle DNA, your goal will be to narrow down the genomic location of the candidate gene. Your next task will be to perform genome scanning, which involves an analysis of the entire genome and identifying the candidate gene by using short tandem repeats (STRs) as markers. Our simulation model assumes that a 10 base DNA sequence will experience one mutation every million years, each base in the sequence is equally likely to change, and each type of mutation is equally likely. RNA polymerase adds RNA nucleotides complimentary to the DNA strand 3. A mutation is a change in DNA, the hereditary material of life. To make sure that each new cell has the exact same DNA as the parent cell, DNA can make a copy of itself. You will then draw a blood sample, and from that, extract DNA and perform further experiments in the lab. The key to dna profiling is amplification of the copies present. By studying the pedigree, you will learn about heritable traits and whether double muscling is autosomal or sex-linked and whether it is dominant or recessive. In your first task you will fill in a pedigree to help identify the double muscled cattle.
These are suggestions for the order of DNA bases. With this Activity, simulate RNA Transcription and get the Templates for RNA and DNA nucleotides. Take the Tour of the Basics at the Genetic Science Learning Center.

Or download the PDF files for Instructions and Template. You will use polymerase chain reaction (PCR) and gel electrophoresis to perform genotyping in order to identify the gene that causes double muscling in cattle.Īs a researcher you will be called to a farm to investigate a case about double muscled cattle. Answer: 3 on a question A DNA sequence is shown. Make an Origami DNA model at DNAi website. In the Animal Genetics simulation you will learn about Mendelian inheritance and how a mutation in DNA can give rise to an altered phenotype. Genetics Module B, Anchor 3 Key Concepts: - An individual s characteristics are determines by factors that are passed from one parental.
