Chapter 12, Problem 12.1CR

Differentiate between these terms: chromosome, chromatin, and chromatid.

Expert Solution & Answer

Summary Introduction

To differentiate: Between chromosomes, chromatin, and chromatid.

Introduction: Chromatin is a complex macromolecule, which contains DNA, protein as well as RNA. Chromosome is a densely packaged chromatin. It is a thread like structure present in nucleus of the cell. A chromosome has a constriction point in the middle called centromere. Chromosomes duplicate during the process of cell division and form sister chromatids, which further gets separted into two chromosomes.

Explanation of Solution

Chromosome, chromatin, and chromatid all occur in the nucleus of the cells, but have some basic differences. The difference between chromosomes, chromatin, and chromatid is shown below:

Criteria	Chromosomes	Chromatin	Chromatid
Definition	Chromosomes is condensed form of chromatin, which contains DNA and proteins.	Chromatin is very fine interdispersed form of DNA associated with protein and RNA.	The identical pieces of DNA that is held together by acentromere and pulled apart in the cell division process to make new identical cells that are called sister chromatids.

Three of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results: Trait Number of individuals Wild type 169 Black 19 Black, hooked 301 Dumpy, hooked 21 Hooked, dumpy, black 172 Dumpy, black 6 Dumpy 305 Hooked 8 Determine the order of the genes and the mapping distance between genes. Determine the coefficient of confidence for the portion of the chromosome involved in the cross. How much interference takes place in the cross?

What happens to a microbes membrane at colder temperature?

Genes at loci f, m, and w are linked, but their order is unknown. The F1 heterozygotes from a cross of FFMMWW x ffmmww are test crossed. The most frequent phenotypes in the test cross progeny will be FMW and fmw regardless of what the gene order turns out to be. What classes of testcross progeny (phenotypes) would be least frequent if locus m is in the middle? What classes would be least frequent if locus f is in the middle? What classes would be least frequent if locus w is in the middle?
