Question

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.

Answer 1

Each description provided aligns with specific structures in chromosome anatomy, such as telomeres, centromeres, and origins of replication. The correct sequence that matches the descriptions is "TTOCCCO".

Step-by-step explanation:

To indicate whether each description applies to a centromere (C), a telomere (T), or an origin of replication (O), consider the following:

• (T) It contains repeated sequences at the ends of the chromosomes.
• (T) It is NOT generally longer in higher organisms compared to yeast.
• (O) Each eukaryotic chromosome has many such sequences.
• (C) There are normally two such sequences in each eukaryotic chromosomal DNA molecule.
• (C) There is normally one such sequence per eukaryotic chromosomal DNA molecule.
• (O) It is where DNA duplication starts in S phase.
• (C) It attaches the chromosome to the mitotic spindle via the kinetochore structure.

The correct seven-letter string composed of the letters C, T, and O only is "TTOCCCO".
