what is the difference between g1 and g2 phase?
9634
One significant difference between growth phases is that the first growth phase is about cell growth while G2 is about cell division.

The cell cycle has two major phases: interphase and the mitotic phase (Figure 1). During interphase, the cell grows and DNA is replicated.

The cell cycle is a 4-stage process consisting of Gap 1 (G1), Synthesis, Gap 2 (G2) and mitosis.

One of the key differences between the cell cycle and mitosis is the length of each process. The cell cycle can extend throughout the cell's entire life depending on how fast it divides. ... Only during G2, S, and M does the cell have double the DNA. In mitosis, until the cell divides it always has double the DNA.

The only difference is the size - Zone 1 measures 43cm, the 2 is 60 - and the further north you live the more likely you are to need the larger.

A stage 1 clutch is easier to install and use than a stage 2 clutch. ... A stage 1 clutch also does not wear your engine out as fast as a stage 2 clutch might, and it does not affect your car's street legality. Finally, a stage 1 clutch is easier to shift than a stage 2 clutch.

The greatest difference between Stage 1 and Stage 2 is the addition of starch in Stage 2. While some younger babies have not developed enough to digest starch easily, it is an ideal addition to a formula that meets the hunger of a baby who is not completely satisfied with Stage 1.

In a eukaryotic cell, the cell cycle has two major phases: interphase and mitotic phase. During interphase, the cell grows, performs routine life processes, and prepares to divide.

A stage 1 clutch is easier to install and use than a stage 2 clutch. ... Finally, a stage 1 clutch is easier to shift than a stage 2 clutch. This is because stage 2 clutches are designed for more professional use, and they put more pressure on the engine by removing the features that allow the user more leeway in shifting.

No, because DNA is replicated in Interphase first and no interphase stage exists after after Meiosis 1. Describe the main difference between Metaphase 1 and Metaphase 2. In Metaphase 1, paired homologous chromosomes line up along the equator of the cell. ... It is a regular mitosis when chromosomes are not duplicated.

The difference between Type 1 and Type 2 second degree heart block: Type 1 has increasing PR intervals, increasing until the QRS is "dropped" or missing. Type 2 has constant PR intervals, with randomly dropped QRS complexes.

Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. Both produce two daughter cells from each parent cell.

At the G1 phase of the cell cycle, each chromosome consists of a single chromatid and each chromatid consists of a single double-stranded DNA molecule. Therefore, a cell that normally has 12 chromosomes will have 12 DNA molecules in G1.

G1 Phase: In G1, the cell is growing. In most organisms, the majority of the cell's life span is spent in G1. S Phase: In each human somatic cell, there are 23 pairs of chromosomes; one chromosome comes from the mother and one comes from the father. These pairs are known as homologous chromosomes or homologues.

G1 cyclins bind to Cdk proteins during G1. Once bound and activated, the Cdk signals the cell's exit from G1 and entry into S phase. When the cell reaches an appropriate size and the cellular environment is correct for DNA replication, the cyclins begin to degrade.

In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides.

G1, G2, and the full G licence are the three stages of the Ontario graduated licensing program. Every driver must go through the G1 and G2 stages within five years. If you don't get the full G licence after five years, you must start over. Here's a primer on understanding the system and what each stage means.
