Packing Up the Genome Lecture Notes

These flashcards cover key concepts related to the genome, DNA, and genetic terminology as outlined in the lecture notes.

What is a genome?

All the DNA in a cell’s nucleus.

What is the difference between diploid and haploid?

Diploid refers to cells containing two complete sets of chromosomes, whereas haploid refers to cells containing one complete set of chromosomes.

Define a gene.

A gene is a segment of DNA that influences a specific trait.

What is a locus in genetics?

A locus is the specific physical location of a gene on a chromosome.

What is an allele?

An allele is a variant form of a gene that may produce different traits.

What is a trait?

A trait is a characteristic that is expressed as a result of the interaction of one or more genes.

What is karyotyping?

Karyotyping is a laboratory procedure that analyzes the number and structure of chromosomes in a cell.

What are the stages of DNA packaging?

The stages of DNA packaging involve the folding and organizing of DNA to fit within the nucleus, often involving histones and other proteins.
