synapsis takes place between:
spindle fibre and centromere
mrna and ribosomes
a female and a male gamete
two homologous chromosomes
clear my selection
2 multiple choice 2 points
of the following meiotic phases, ___ is most similar in behavior to the mitotic phase of the same name.
prophase ii
anaphase i
metaphase i
none of the above
clear my selection

Explanation:

• Question 1: Synapsis is a process that occurs during meiosis. It involves the pairing of homologous chromosomes. Spindle fibre and centromere interaction is related to chromosome movement during cell division. mRNA and ribosomes are involved in translation. A female and a male gamete fuse during fertilization.
• Question 2: Prophase II in meiosis is similar to prophase in mitosis as in both, chromosomes condense, nuclear envelope breaks down etc. Anaphase I in meiosis separates homologous chromosomes while anaphase in mitosis separates sister chromatids. Metaphase I in meiosis has homologous chromosomes aligned at the equator while in mitosis, individual chromosomes (with sister chromatids) are aligned.

Answer:

1. Two homologous chromosomes
2. Prophase II
