Answer:
Explanation:
This is because the new cell is produced asexually. Therefore the mutated cells are similar to the parent.
Asexual reproduction refers to the process where a parent plants reproduce or replicate new plants by itself and the new plants carries the same set of chromosomal numbers thereby been genetically identical to the parent.
There are many facts about arachnids.
Here are some:
1. Arachnids are invertibrates (No backbone)
2. Arachnids include spiders, mites, harvestmen, and pseudoscorpions.
The scientific name is Arachnida, and the higher classification name is Chelicerata.
(G1) - The stage where the cell spends most of it's life. Doing it's job (job being what the cell was created for, such as being a muscle or bone cell.) and being alive.
(S) - S phase is where cell performs synthesis (Hence the name of the stage, S.) and duplicates it's nutrients and everything inside it, most importantly though you must know that this is the stage where DNA is copied.
(G2) - This is the stage where the cell is preparing to entire mitosis, it's also known as the pre-mitotic phase. This phase takes place immediately after DNA has been replicated in the S phase. After the G2 phase is finished, mitosis begins.

Answer:
Explanation:
Operator region are region of DNA (deoxyribonucliec acid) that repressors protein binds to prevent transcription.
Repressor is an example of regulatory protein they regulate the rate at which transcription of operon occurs . A repressor functions when its bounded to the operator and it prevent enzyme RNA (ribonucliec acid)polymerase from moving to DNA to transcribe the nitrogenous bases by placing a complementary base pair.
Activators are other regulatory proteins that bounds to its DNA binding site and increases transcription of the operon.
