Answer:

A cell that has duplicated chromosome  cannot be in<u> G1 phase.</u>

Explanation:

  • G1, G2 and S phase are the divisions of the interphase i.e. the resting phase of the cell cycle.
  • A cell cycle has two phases; interphase and M-phase.
  • During interphase the cell grows and in M-phase it divides.
  • G1 is the Gap between the M-phase and the S-phase.
  • G2 is the gap between the S phase and M phase.
  • DNA replication is confined to the S part of interphase.
  • Since G1 phase comes before the S phase , we can say that a cell that has duplicated chromosome cannot be in G1 phase.

How do structures and functions of organisms vary in different kingdoms????
Alexxx [7]

Answer:

With millions of different kinds of organisms in the world, scientists must find order in all of this diversity. Scientists group living organisms into one or more of a few major categories as part discipline known as taxonomy. The bodies of organisms are organized into functional systems—cells are organized into tissues, and tissues are organized into organs. Body systems carry out critical functions, such as locomotion, reproduction, digestion, and circulation. All living things on Earth are composed of the same carbon-based, molecular building blocks.

Which of the following statements about change in ecosystems is true?
neonofarm [45]
Ecosystems experience change through human activity and natural events. This is because human activity can impact changes in nature, like climate for example. As a result, ecosystems change in response to the change in nature or natural events, which was caused by human activities. They are interrelated so to speak.

In E. coli, there is a mutation in a gene called dnaB that alters the helicase that normally acts at the origin of replication.
kvasek [131]

Answer:

When helicase mutations occur, problems in DNA replication are found. The helicases are proteins that open the 2 strands of DNA to initiate the duplication, they are responsible for breaking the hydrogen bonds between the two DNA chains, thus separating the chains, also they have the function of repairing DNA mutations, if there is mutation in the gene that encodes them, various functions will be absent in the cell.
