What is the difference between a chromosome and a replicated chromosome?

Chromosomes consist of DNA (deoxyribonucleic acid, the information-carrying molecule in chromosomes) and structural proteins. … A replicated chromosome (or equivalently, a duplicated chromosome) contains two identical chromatids, also called sister chromatids.

What is the difference between single and replicated chromosomes?

Sexual reproductive cells have only one sample of each chromosome. An unreplicated chromosome contains one double strand -DNA molecule. A replicated chromosome contains two identical double strand -DNA- molecules, the chromatids, that are joined at their centromere.

What is the difference between DNA replication and chromosome duplication?

Replication refers to the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules while duplication refers to the process by which the amount of DNA inside the nucleus gets doubled.

What is a replicated chromosome called?


A chromatid is one of two identical halves of a replicated chromosome. … Following DNA replication, the chromosome consists of two identical structures called sister chromatids, which are joined at the centromere.

What are the differences between replicated and unreplicated chromosomes?

These are known as unreplicated chromosomes. During the S phase, the unreplicated chromosomes replicate. The replicated strands are called sister chromatids, which are identical copies of each other connected at the centromere. Each homologous pair of chromosomes has two pairs of sister chromatids.

What is a replicated chromosome composed of?

FEEDBACK: A replicated chromosome consists of two sister chromatids that are held together at the centromere. During S phase, the replicated chromosomes are produced in preparation for mitosis. It is during mitosis that the replicated chromosome is split in two. homologous chromosomes exchange genetic information.

What is the difference between replicated and duplicated?

Trick to Remember the Difference

A duplicate is an exact copy of something. A replicate is only a reproduction, even if it is not exact.

What is difference between replication and duplication?

The main difference between replication and duplication of DNA is that replication is the synthesis of an exact replica of DNA while duplication is the doubling of the amount of DNA as a result of replication.

What are the differences between replication and transcription?

DNA replication is the process of making two daughter strand where each daughter strand contains half of the original DNA double helix. Transcription is the process of synthesis of RNA using DNA as a template.

What are condensed chromosomes?

Synonyms: cytoplasmic mitotic chromosome | metaphase chromosome | mitotic chromosome. Definition: A highly compacted molecule of DNA and associated proteins resulting in a cytologically distinct structure.

How many chromosomes are in a duplicated chromosome?

The genetic material of the cell is duplicated during S phase of interphase just as it was with mitosis resulting in 46 chromosomes and 92 chromatids during Prophase I and Metaphase I.

Why do replicated chromosomes consist of two sister chromatids?

Explanation: When chromosomes are duplicated and are still connected at the centromere they are called sister chromatids and make up one chromosome. The sister chromatids look like an X. Once they are separated they are no longer chromatids but chromosomes again.

How many replicated chromosomes are in the original cell?

Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.

Are chromosomes replicated or unreplicated in anaphase?

To make this happen, replicated chromosomes condense (prophase), and are positioned near the middle of the dividing cell (metaphase), and then each of the sister chromatids from each chromosome migrates towards opposite poles of the dividing cell (anaphase), until the identical sets of unreplicated chromosomes are …

How many strands of DNA are in a replicated chromosome?

In the diagram, (1) refers to a chromatid: 1-half of two identical threadlike strands of a replicated chromosome. During cell division, the identical copies (called a “sister chromatid pair”) are joined at the region called the centromere (2).
