Answer:
Mitosis is a type of cell division in which a single parent cell is divided into two daughter cells. Before mitosis, replication of chromosome occurs in which two copies are formed from a single set of chromosome. These two copies of chromosome are distributed among the daughter cells.
Cytokinesis is the phase of cell division in which cytoplasm of the cell is divided into two equal parts and distributed to each daughter cell.
Answers: A. (DNA replication is semiconservative), B. (DNA is replicated so that each daughter cell will have half of a DNA molecule), and C. (The cell enters S phase with two copies of each of its chromosomes)
It is because it's easy for them to propagate there.......
Saliva is a part of the digestive system. saliva contains enzymes that help start the breakdown of food in the digestive process
Answer:
A promoter and a start codon are similar in that both are sequences of Nucleic acid that are required to start important processes, and both determine the sites where the process will begin. The key differences are that the promoter is needed to start transcription and the start codon is needed to start translation. Also, the promoter is a DNA sequence only, and the start codon is a sequence found within a(n) mRNA .
Explanation:
The promoter is the sequence of DNA that serves as a binding site for RNA polymerase. The RNA polymerase is the enzyme of transcription. Promoters are required to start the process of transcription. Transcription is the process of making RNA copies of the DNA template strand.
The start codon is the first codon in mRNA that is translated during protein synthesis. The start codon marks the start of the protein-coding region of the mRNA. Binding of aminoacyl tRNA with complementary anticodon to the mRNA start codon begins the process of translation.
