Importance of DNA: DNA is the ultimate blueprints for the entire cell. Often referred to as the genetic material of the cell, DNA holds all the information needed for cell structure and function. Answer and Explanation:1 The point of DNA replication is to make two identical daughter copies of...
Bioinformatics analysis of the data found that genes of the DNA replication/DNA metabolism process group (with upregulation of the apex1, mcm2, mcm4, orc3, lig1, and dnmt1 genes) were altered in the DM state and these molecular changes continued into MM. Interestingly, DNA methylation ...
Types of Mutation Types of Point Mutations Lesson Summary Register to view this lesson Are you a student or a teacher? FAQ What is a point mutation, and how does it occur? A point mutation is a change in a single base in DNA. It can occur through natural errors in replication or throu...

In a Chlorella culture growing synchronously at pH 6.3 under a 12 hr light/12 hr dark regime, DNA replication occurs between the 8th and the 12th hour of the cycle, the main period of protein and chlorophyll synthesis occurring between the 4th and 12th hour of the cycle. When the culture...

Activation of S-phase-promoting CDKs in late G1 defines a "point of no return" after which Cdc6 synthesis cannot promote DNA replication in yeast. In eukaryotic cells, DNA replication is confined to a discrete period of the cell cycle and does not usually recur until after anaphase. In th...

Point mutations are frequently the result ofmistakes made during DNA replication, although modification of DNA, such as through exposure to X-rays or to ultraviolet radiation, also can induce point mutations. There are two types of point mutations: transition mutations and transversion mutations. ...
Retroviruses utilize the viral integrase (IN) protein to integrate a DNA copy of their genome into host chromosomal DNA. HIV-1 integration sites are highly biased towards actively transcribed genes, likely mediated by binding of the IN protein to specifi
