what is DNA
what is DNA?
contains the genetic information about who we are and in all living things.
Inside the nucleus, DNA is called around the structure.
chromosomes
what is the purpose of an enzyme
speed up a chemical reaction
Who came up with predicting what offspring would look alike by using a pea plant?
Mendel
how is meiosis different from mitosis interns of chromosomes number?
meiosis result in haploid cells,mitosis resulted in diploid cells
give an example of a gene and an allele to explain the difference between them?
gene eye :eye color allele:Blue eye color
The backbone of DNA is made of what?
sugar and phosophate
what enzyme does this represent where it unzips the DNA
helicase
what is the probabilty of getting a homozygous rescessive offspring from two heterozygous parents?
25%
four daughter cells that are haploid,
how many allele per gene?
In the phase stages, this occurs which helps increase genetic variation
crossover
which enzyme adds new nucleotides during DNA replication
DNA polymerase
what is homozygous dominate example
example:HH
At which stage of meiosis are sister chromatids separated from each other?
anaphase II,
red and blue make purple flowers what dominates is it?
incomplete dominance
How do organisms live, grow, respond to their environment and reproduce?
natural selection.
which enzymes fill in the Okazaki fragment
Ligase
what is heterozygous recessive Example:
Example:hh
the chiasmata.
Name one purpose of the human genome project.
Genetic variation, and advances in medicine, identify the number of genes.
How do organisms obtain and use the matter and energy they need to live and grow?
Plants acquire material for growth chiefly from air, water, and process matter and obtain energy from sunlight,
what are 3 things enymes are affected by
Temperature , PH, and concentration
What percentage of offspring produced by two parents with blue eyes would also have blue eyes?
100%.
All somatic cells are produced by mitosis.
