Chapter 14, Problem 1TY

Summary Introduction

Introduction:

The cell cycle is the complete cycle of the cells starting from the formation of the cells by mitosis and ends with the next mitosis. The cycle is divided into G1 phase, S phase, G2 phase and mitotic phase.

Expert Solution & Answer

Answer to Problem 1TY

Option (b).

Explanation of Solution

Explanation for the correct answer:

Option (b) S phase. The S phase is the synthetic phase of the cell cycle. In this phase of the cell cycle, the amount of DNA and chromosomes are doubled by the process of DNA replication. Hence, it is the correct answer.

Explanation for the incorrect answer:

Option (a) G1 phase. The G1 phase of the cell cycle is responsible for the growth and promotion of the cell size. Hence, it is an incorrect answer.

Option (c) M phase. Mitosis is the process of the celldivision, which occurs in all the somatic cells present in the body of the multicellular organism. IN this stage, the replication does not take place. Hence, it is an incorrect answer.

Option (d) G2 phase. The G2 phase occurs after S phase, so, there is no need of DNA replication. Hence, it is an incorrect answer.

Option (e) none of the above. The replication of the DNA segment or the chromosomes occur in S phase. Hence, it is an incorrect answer.

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?

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?
