Biology - Chapter 8 HW

A cell in early interphase has 10 chromosomes. How many chromatids will the same cell have during prophase?

20

DNA replication occurs during interphase. Which image shows the products of replication, if the parent strands are blue and the new strands are red?

C

Given the sequence of DNA below, what would be the sequence of bases on the daughter strand after DNA replication?

CCGGCCGATGGT

Consider how the image of a replicated chromosome below relates to DNA replication. Then, select the one true statement.

Each chromatid has a daughter strand and a parental strand of DNA

Mitosis includes interphase and cytokinesis.

FALSE

When in the cell cycle does DNA replication occur?

Interphase

Where in the cell cycle is DNA polymerase most active? Click the correct box.

S

Sister chromatids separate during anaphase.

TRUE

Replication creates a complementary strand of DNA. Given the following parental strand of DNA, what would be the nucleotide sequence of the daughter strand? AACTGGCATCGACTAGGG
