What is the role of the nucleus in cell division?Question:What is the role of the nucleus in cell division?The Nucleus:In eukaryotic cells, the nucleus holds the DNA. DNA is arranged in long strands, each being called a chromosome. The normal human nucleus has 46 chromosomes. These chromos...
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...
DNA Structure: DNA structure is the arrangement of molecules that make up the DNA molecule. The structure determines how it interacts with other molecules. The DNA molecule is a double helix-shaped like a twisted ladder. Answer and Explanation: 1 There are three levels to DNA structure; the...
