Which are replicated during interphase?

Answers

Answer: The correct answer is-

DNA molecules or chromosmes are replicated during the interphase.

Interphase is first stage in the cell cycle. It is further divided into three phases that is-

G1 ( first growth phase, during which cell grows and syntheises essential proteins for replication),

S ( synthesis phase as chromosomes are replicated during this phase). This important before cell divides in the M phase.

G2 phase ( second growth phase). During this, further growth of cell takes place and it prepares for division in the next stage that is M phase.

Which feature is found in eukaryotic cells but not in prokaryotic cells? A. plasma membrane B. nucleus C. cytoplasm D. genetic material

Answers

B is the correct answer

A prokaryote cell has no distinct nucleus with a membrane and neither does it have other specialized organelle.

In a eukaryotic cell, the genetic material is DNA in the form of chromosomes which are found within a distinct nucleus.

Examples of prokaryotes Streptomyces soil bacteria (from which streptomycin antibiotic is derived), Escherichia coli bacterium and Streptococcus bacteria (which causes strep sore throat).

Examples of Eukaryotes include protozoa such as amoeba, fungi, plants, animals and generally all  multicellular organisms.
