What are the frist 3 stages of the cell cycle called?

Answers

The first three stages of the cell cycle are collectively called the "Interphase". Interphase comprises 3 stages specifically G1, S1 and G2. G1 is called the First Gap Phase, followed by S phase for synthesis and then G2 for the second gap phase. I hope this helps you. 
Interphase proceeds in three stages, G1, S, and G2, preceded by the previous cycle of mitosis and cytokinesis. The cell's nuclear chromosomes are duplicated during S phase.

Enzymes, such as the one shown in the picture, work by fitting onto the substrate molecule like a lock-and-key action. Which statement is true, with regard to the enzyme and the substrate?

Answers

Answer;

A)  The enzyme weakens chemical bonds in the substrate and catalyzes a change into the product. The enzyme itself remains unchanged.

Explanation;

  • Enzymes are biological catalysts that speed up chemical reactions. Enzymes catalyze or speed up a reaction by binding to a substrate using its active site.
  • The active site of an enzyme is suited to bind a particular substrate, that is why enzymes are known to substrate specific.
  • The binding of the substrate to the enzyme results to changes in the distribution of electrons in the chemical bonds of the substrate and consequently leads to  reactions that lead to the formation of products.
The enzyme weakens chemical bonds in the substrate and catalyzes a change into the product. The enzyme itself remains unchanged.

The options for these are Monocot food, Dicot food, Monocots, and Dicots

Answers

Mono cots and dicots both have differences which are

Mono cots have one seed leaf while dicots have two seed leaves

Monocots have parallel leaf structure while dicots have netted leaf structure

Monocots store their food in the endosperm while on the other hand the dicots store their food in the cotyledons.

one seed leaf: monocot

netted leaf structure: dicot

parallel leaf structure: monocot

cotyledons: dicot food

endosperm: monocot food

Which statements about the regulation of transcription initiation in these genes are true?1) The fantasin gene will be transcribed at a high level when activators specific for control elements A, B, and C are present in the cell. 2) Both the fantasin gene and the imaginin gene will be transcribed at high levels whenever general transcription factors are present in the cell. 3) The imaginin gene will be transcribed at a high level when repressors specific for the imaginin gene are present in the cell. 4)Control elements C, D, and E are distal control elements for the imaginin gene. 5)The fantasin gene and the imaginin gene have identical enhancers. 6)Control elements A, B, and C are proximal control elements for the fantasin gene 7)Both the fantasin gene and the imaginin gene will be transcribed at high levels when activators specific for control elements A, B, C, D, and E are present in the cell.

Answers

a and c are the elements

Final answer:

Statement 1 is true, Statement 2 is false, Statement 3 is false

Explanation:

1) Statement 1 is true. The fantasin gene will be transcribed at a high level when activators specific for control elements A, B, and C are present in the cell. These activators bind to the control elements and enhance the transcription of the fantasin gene.

2) Statement 2 is false. While general transcription factors are necessary for transcription in general, the specific control elements for each gene determine the level of transcription. So, the presence of general transcription factors alone does not guarantee high levels of transcription for the fantasin and imaginin genes.

3) Statement 3 is false. The imaginin gene will not be transcribed at a high level when repressors specific for the imaginin gene are present in the cell. Repressors bind to control elements and inhibit transcription, leading to reduced levels of transcription for the imaginin gene.
