Question 11

What is chromatin?

Answer 11

Thread like strands of DNA present in interphase (I between mitosis and meiosis). Not visible under a microscope.

Question 12

What do double stranded chromosomes consist of?

Answer 12

Two identical chromatids held together by a centromere.

Question 13

What are homologous chromosomes?

Answer 13

A pair of chromosomes containing the same genes, but possible with different alleles (characteristics). One is paternal and one is maternal.
