What 2 structures make up a single replicated chromosome?

Following DNA replication, the chromosome consists of two identical structures called sister chromatids, which are joined at the centromere.

What structures make up a single replicated chromosome?

The two structures make up a single replicated chromosome is sister chromatids. The term ‘sister chromatid’ only applies when the identical copies are closely associated with one another and held together by a centromere.

What are two strands replicated chromosomes?

In replication, the DNA molecule is copied, and the two molecules are known as chromatids. During the later stages of cell division these chromatids separate longitudinally to become individual chromosomes. Chromatid pairs are normally genetically identical, and said to be homozygous.

What holds the 2 halves of a chromosome together?

The two chromatids of a chromosome are attached at a point called a centromere. The centromere holds the two chromatids together until they separate during cell division.

What two structures make up a chromosome?

DNA and histone proteins are packaged into structures called chromosomes.

What are the 4 steps of replication?

What are the 4 steps of DNA replication?

  • Step 1: Replication Fork Formation. Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands.
  • Step 2: Primer Binding. The leading strand is the simplest to replicate.
  • Step 3: Elongation.
  • Step 4: Termination.

What is the correct order of these meiotic events?

The correct order of mitotic events which occur during meiosis is: Formation of synaptonemal complex, recombination, separation of homologous chromosomes, separation of sister chromatids.

What are the two parts of cell division?

There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells.
