Mitosis

Question 1

What are the 4 types of noncoding DNA sequences?

Answer 1

1. Transcription/Translation regulators
2. Origins of DNA replication
3. Centromeres
4. Telomeres

Question 2

What are the 4 phases of a cell?

Answer 2

G1, S, G2, Mitosis

Question 3

What happens during G1 Phase?

Answer 3

The beginning of cell life where centrioles start to divide, cell grows to full size, DNA is in single strands, and TRANSLATION/TRANSCRIPTION occur

Question 4

What happens during S Phase?

Answer 4

DNA replicates, diploid & haploid, centrosomes and centrioles replicating.

Question 5

What happens during G2 Phase?

Answer 5

nucleus is well defined, centrosomes are present, DNA is duplicated, RNA is transcribed to make proteins.

Question 6

Mitosis: What happens during Prophase?

Answer 6

The chromatin fibres condense and the chromosomes are now visible as 2 identical sister chromatids.

Question 7

Mitosis: What happens during Prometaphase?

Answer 7

Chromatin fibres are fully condensed and kinetochore appear.

Question 8

Mitosis: What happens during Metaphase?

Answer 8

Chromosomes line up and attach to the spindle fibres at the centromere.

Question 9

Mitosis: What happens during Anaphase?

Answer 9

Sister chromatids separate through the spindle fibres that pull them apart into separate chromosomes.

Question 10

Mitosis: What happens during Telophase?

Answer 10

Chromosomes decondense, nuclear envelope forms, you now have 2 daughter cells.
