Indicate whether each of the following descriptions better applies to a centromere (C), a telomere (T), or an origin of replication (O). Your answer would be a seven-letter string composed of letters C, T, and O only, e.g. TTTCCTO.
( ) It contains repeated sequences at the ends of the chromosomes.
( ) It is NOT generally longer in higher organisms compared to yeast.
( ) Each eukaryotic chromosome has many such sequences.
( ) There are normally two such sequences in each eukaryotic chromosomal DNA molecule.
( ) There is normally one such sequence per eukaryotic chromosomal DNA molecule.
( ) It is where DNA duplication starts in S phase.
( ) It attaches the chromosome to the mitotic spindle via the kinetochore structure.

Quizplus · Accepted Answer

There is normally one centromere per chromosomal DNA molecule, and two per mitotic chromosome. The mitotic kinetochore structure forms at the centromere. In contrast, the telomeres are at the two ends of each linear chromosome. There are usually many replication origins per eukaryotic chromosome. Replication origins and centromeres are both generally much longer in higher eukaryotes compared to yeast.
