What is the role of DNA polymerase in DNA replication? DNA: DNA, or deoxyribonucleic acid, is an important part of the cell because it contains all the genetic information that is needed to make a new cell or even a whole new organism. Because of this, DNA is often copied to produce ...
What is the role of DNA electrophoresis in DNA fingerprinting? DNA and Chromosomes Every individual has deoxyribonucleic acid (DNA) in each cell. DNA is tightly coiled into units called chromosomes. A somatic cell, also known as a body cell, that is free of chromosomal mutations contains a ...
Mutations in DNA repair genes are commonly found in cancer cells, and it has been suggested that POLQ may be involved in DNA repair1. Therefore, the aim of the DPhil project in our laboratory would be to investigate the role of POLQ in DNA repair in human cancer cells. We would like ...
Western blot analysis of the lysates from K562 cells using SRY antibody. SOX-9 下图为石蜡组织切片,SOX-9染色,胞核阳性。 SOX-9 [1] Sox9 expression during gonadal development implies a conserved role for the gene in testis differentiation...
Answer: Each strand of DNA carries a particular sequence of nitrogen bases. These serve as genetic code that is passed on to mRNA, mRNA carries a message, it has copy of the genetic code passed to it by DNA. Then tRNA transfers the amino acids to rRNA, rRNA plays a structural role in...
What is the end product of replication?Two identical DNA strands. Each one is made of one original strand and one new strand. What is the role of DNA polymerase in replication? What happens first in DNA replication? The initiation of DNA replication occurs in two steps. First,a so-called...
