The correct answer is the interphase.
The cell cycle consists of three phases: the interphase (G1, S, G2) the mitotic (M) phase, and cytokinesis. <span>The first checkpoint of the cell cycle is G1 checkpoint which is between G1 and S phase when cell checks its size, nutrients, molecular signals, DNA integrity. The second checkpoint is G2, just before the mitotic phase, when cell checks DNA integrity and DNA replication. Those two checkpoints are the ones before division, other like M checkpoint is during the mitosis.</span>
Answer: frameshift mutation
Explanation: A frameshift mutation is a particular type of mutation that involves either insertion or deletion of extra bases of DNA. Now, what's important here is the number three. The number of bases that are either added or subtracted can't be divisible by three.
The options of the given question are:
method for DNA delivery
gene construct
efficient selection strategy
tissue culture system
Answer: Tissue culture system.
Explanation:
The role of tissue culture system is not much in case of the transgenic plant. The method of DNA delivery, efficient selection strategy and gene construct are involved in the plant transformation.
But plant tissue culture is not directly involved in the plant transformation. The plant tissue culture is the collection of the techniques which is used to maintain the growth of the plant cells and so it does not plays any important role in plant transformation.
The plant transformation is the introduction of the desired characters into the plant and then the growth of transformed plant takes place in the culture medium. This has no role in the plant transformation or has less role.
Answer:
The Mendelian principles of inheritance ARE APPLIED IN HUMANS. Both plants and animalls posseses two alleles (forms) of each gene, and are inherited in Mendelian ways. Some genetic diseases are Mendelian diseases and are inherited according to Mendel laws, those are the diseases caused BY A SINGLE GENE. However, there are multigenic diseases (that involves more than one gene), multifactorial diseases (which involves several genes and environmental factors), and chromosomic diseases (like 21 trisomy) and all of these does not follow the Mendel laws.
Explanation:
Vascular plants have specialized transporting cells.
