How do genes determine the traits of an organism? How does the Chromosomal Theory of Inheritance helped to advance our understanding of genetics? What is the detailed meaning of the term genetics? How can characteristic patterns of growth be explained by genetically determined processes?
How could you determine the distance between two genes using experimental mating? How many autosomal genes are there? How do you graph to represent the distribution of traits? (inheritance) How does independent assortment of chromosomes increase genetic diversity? How do Mendelian laws such as the...
How much of the gene pool is extinct? Species Extinction: The history of life on Earth is told in the fossil record beneath our feet. However, many fossils abruptly vanish from the record after key dates, indicating that they went extinct because they could no longer adapt to environmental ...
How DNA Works: Structure and Functions EQ: How do genes and chromosomes work together to determine an organism’s traits? DNA Basics Almost every cell in your body contains about 2 meters of DNA. If you unraveled all your chromosomes from all the cells of your body, then laid out the DNA...
How does RNA polymerase choose which strand to start to use as a template? a. RNA can only transcribe from the strand with the most major units. b. Certain sequences called promoter regions determine where transcription begins. c. RNA can only transcribe ...
Believe it or not, your skin’s journey begins with the genetic code handed down from your parents. Genes determine the structure, elasticity, and overall appearance of your skin—such as texture, color, and sensitivity Tip:Tailor your skincare routine to your genetic traits by identifying your...
How does CRISPR edit DNA? Who discovered CRISPR? How has CRISPR been used? What are potential risks of CRISPR? CRISPR, short for CRISPR-Cas9, is a genome-editing tool that allows scientists to precisely cut and modify DNA sequences. It has revolutionized the study of genes, helped to...
DNA is found in the nucleus of every human cell. The information in DNA: guides the cell (along with RNA) in making new proteins that determine all our biological traits gets passed (copied) from one generation to the next The key to all of these functions is found in the molecular ...
How can a non-genetic factor like nutrition have effects passed down over generations? How natural selection influences discrete traits? What is the major difference between a trait and a gene as defined in genetics? Which plays a bigger part in IQ, environment, or genetics? How does environmen...
How are the genes and alleles associated with genetic traits determined? Explain one reason why this process is difficult and not always exact. Alleles: Alleles are variations in the sequence of a gene and are they give rise to different ...
