Indicate if each statement is True or False.
(a) A bivalent contains one centromere, two sister chromatids, and one homolog.
(b) A bivalent contains two centromeres, four sister chromatids, and two homologs.
(c) A bivalent contains two linear, duplex DNA molecules.
(d) A bivalent contains four linear, duplex DNA molecules.
(e) A bivalent contains eight linear, duplex DNA molecules.
Homework Answers
A- false
b- true
c- false
d- true
e- false
note-the bivalent is the tetrad seen i the chromosome durng prophaseI the bivalents is pair of homologous chromosome which is formed when two replicated homologs come together and form tetrad having sister chromatids.

3. (4 pts). A diploid somatic cell of a hypothetical eukaryote contains two pairs of homologs in its nucleus (2N = 4). One pair of homologs is metacentric and the other pair is submetacentric. The metacentric pair is heterozygous at two gene loci and each locus is on a different arm. At one locus, the alleles are identified by the letters “A” and “a”. At the other locus, the alleles are identified by the letters “B” and “b”. The upper...

Which of the following statements are true? Select one or more: a. Two sister chromatides arise by replication of the DNA of the same chromosome and remain paired as they line up on the metaphase plate b. Microtubule polymerization and depolymerization and microtubule motor proteins are all required for DNA replication during 5 Phase X C. Centrosomes are duplicated before M Phase begins d. Microtubules nucleate at the centromeres and then connect to the kinetochores, which are structures at the...

Indicate whether each of the following statements is true or false. Statement True False Two countries can gain from specialization and trade as long as they have different opportunity costs in the production of some goods. The gains from specialization and trade are based on absolute advantage. If a certain trade is good for one country, it must be good for the other country. Two individuals can benefit from trade even if neither has a comparative advantage in some activity. Workers in importing industries are...
