question 1 (0.5 points)
listen
the area of the nucleus rich with enzymes needed for dna transcription.
a) cleavage furrow
b) centrosome
c) cell plate
d) nucleolus
question 2 (0.5 points)
listen
a zipper-like protein that holds together homologous pairs during prophase i.
a) synapsis
b) chiasmata
c) cleavage
d) synaptonemal complex

Explanation:

• Question 1:
• The nucleolus is a region within the nucleus. It is involved in ribosome biogenesis and contains enzymes and proteins necessary for processes like DNA transcription.
• A cleavage furrow is related to cell division (cytokinesis) in animal cells.
• A centrosome is involved in organizing microtubules and is important for cell division.
• A cell plate is formed during cell division in plant cells.
• Question 2:
• The synaptonemal complex is a zipper - like protein structure that holds homologous chromosomes together during prophase I of meiosis.
• Synapsis is the process of homologous chromosomes coming together, not the protein structure.
• Chiasmata are the points of crossing - over between homologous chromosomes.
• Cleavage is related to cell division (cytokinesis).

Answer:

Question 1: d) nucleolus
Question 2: d) synaptonemal complex
