19 Questions
What percentage of the genome does the DNA that is transcribed and translated represent?
2 percent
What is the main function of the centromere in a chromosome?
To hold the chromatids together during cell division
What is the difference between mitosis and meiosis?
Mitosis results in the same number of chromosomes, while meiosis results in half the number of chromosomes
What is the dual function of DNA?
Self-replication and protein synthesis
How many pairs of chromosomes do humans have?
23 pairs
What is the relationship between linkage disequilibrium and gene mapping?
Linkage disequilibrium indicates that genes are close enough on a chromosome to be useful for gene mapping
What is the relationship between DNA, RNA, and proteins?
DNA is transcribed into RNA, which is then translated into proteins
What is the structure of DNA?
DNA has a double helix structure
What is the purpose of gene inheritance through chromosomes?
To ensure that genetic information is passed down to offspring
What is the purpose of having only one member of each chromosome pair in a gamete?
To ensure genetic diversity in offspring
What is the significance of linkage disequilibrium between genes?
It implies that the genes are physically close together on the same chromosome
What is the primary function of the centromere in a chromosome?
To hold the chromatids together during cell division
What is the difference between mitosis and meiosis in terms of their outcomes?
Mitosis results in diploid cells, while meiosis results in haploid cells
What is the primary function of proteins in the context of DNA and gene expression?
To carry out the functional roles encoded by genes
What is the significance of having 23 pairs of chromosomes in human cells?
It allows for a greater diversity of gene combinations
What is the relationship between DNA, RNA, and proteins in the central dogma of molecular biology?
DNA is transcribed into RNA, which is then translated into proteins
What is the significance of the double helix structure of DNA?
It allows for the storage of genetic information
What is the purpose of gene mapping in the context of linkage disequilibrium?
To determine the physical location of genes on chromosomes
What is the dual function of DNA mentioned in the text?
Self-replication and protein synthesis
Explore the concepts of variation, heritable traits, and the history of behavioural genetics. Learn about the blending hypothesis, ways variability is induced, and the contributions of Darwin, Galton, and Mendel to the field.
