Who demonstrated that DNA is the genetic material of the T2 phage?
During DNA replication, the leading strand is synthesized continuously, whereas the lagging strand is synthesized as Okazaki fragments. Why is this so?
As DNA replication continues and the replication bubble expands, the parental double helix is unwound and separated into its two component strands. This unwinding and separating of the DNA requires three different types of proteins: helicase, topoisomerase, and single-strand binding proteins.Sort the phrases into the appropriate bins depending on which protein they describe.
In DNA replication in bacteria, the enzyme DNA polymerase III (abbreviated DNA pol III) adds nucleotides to a template strand of DNA. But DNA pol III cannot start a new strand from scratch. Instead, a primer must pair with the template strand, and DNA pol III then adds nucleotides to the primer, complementary to the template strand. Each of the four images below shows a strand of template DNA (dark blue) with an RNA primer (red) to which DNA pol III will add nucleotides.In which image will adenine (A) be the next nucleotide to be added to the primer?

t or f? DNA long molecule encodes all information needed to construct all proteins in an organism
t or f? DNA stays in the nucleus of the cell

How cells contain how many sex chromosomes?
Ratio for two heterozygotes in a simple monohybrid cross

Since there is no recessive allele, you should use?
How many alleles are there that determine blood type?
What ratio did Mendel find for dominant to recessive traits?
Organisms that have two identical alleles for a particular gene
a situation in which the phenotypes produced by both alleles are clearly expressed.
The offspring of crosses between parents with different contrastingcharacteristics
Organisms that have two different alleles for the same gene
bits and pieces of the homologous chromosomes are exchanged and produces new combinations of alleles on each chromosome
