Q

What happens to chromosomes during cell division

A

During cell division chromosomes are split up into sister chromatids, that are held together by centromere’s.

16
Q

Mitosis

A

Produced two cells by division (daughter cells)

17
Q

 prophase

A

Nuclear envelope dissolves, chromatins condense 

18
Q

Metaphase

A

Chromosomes are aligned at the equator of the cell

19
Q

Anaphase

A

Mitotic spindles separate the chromatids

20
Q

Telophase

A

-Chromosomes decondense to return chromatin’s
-nuclear envelope reforms

21
Q

Transcription

A

DNA to RNA

22
Q

Translation

A

RNA to proteins

23
Q

In DNA template strand

A
  • C to G
  • T to A
24
Q

In RNA Template strand

A
  • C to G
  • A to U
