Download Chapter 9 I am - Mrs Smith`s Biology

DNA to act as a template, the four
nucleotides, Appropriate enzymes and ATP
I am the structures that hold genes
DNA Polymerase
Mitosis
I am the process by which a gamete mother
cell nuclei divides to form four daughter
nuclei followed by the division of the
cytoplasm to form gametes
Autosomes
I am name of the bonds that break during
DNA Replication to separate the two
component strands of a DNA molecule
4
I am the name given to chromosome pair
number 23
I am the number of chromosomes that are
found in each new daughter cell compared
to the original cell following mitosis
Sex Chromosomes
I am the name given to the characteristic
number of chromosomes found in the
nucleus of species cells
2n
I am the type of sex chromosomes that a
human female possesses that are fully
homologous to one another
Meiosis
I am the name given to a sex cell/gamete
that possesses a single set of chromosomes
i.e. 23 chromosomes
XY
I am the number of gametes that are formed
from the division of one gamete mother cell
during meiosis
Diploid
I am the name given to a cell that possesses
a double set of chromosomes i.e. 23 pairs
I am the symbol used to represent the fact
that a cell is diploid
n
I am the nucleic acid that genes are made
from
Karyotype
I am the process by which the nucleus of a
normal body cell divides into two daughter
nuclei followed by the division of the
cytoplasm to form two new daughter cells
DNA
I am the chromosome compliment present
in a human body cell
I am the repeating units that a DNA is made
from
I am the type of sex chromosomes that a
human male possesses where only part of
one chromosome is homologous to the
other chromosome
Nucleotides
Chromosomes
XX
46 Chromosomes
Haploid
I am the name given to pairs of
chromosomes that match each other gene
for gene
Chromosome Compliment
I am the symbol used to describe the fact
that a cell is haploid
I am the name given to the appearance of
the chromosome compliment showing the
size, form and number of chromosomes
23
I am the name given to the 22 pairs of
homologous chromosomes that play no part
in sex determination
The same number
I am the process which must occur prior to
meiosis and mitosis to double the quantity
of genetic material so that each new cell
produced contains the correct quantity of
genetic material
2 Chromatids joined by a centromere
I am the number of chromosomes found in
each of the sex cells/ gametes that are
formed during meiosis
I am the name given to the enzyme that
controls DNA Replication
Sugar and Phosphate
I am the name of the chromosomes formed
after DNA Replication
Hydrogen Bonds
I am the four things needed for DNA
replication to occur
I am the two parts of the DNA strand that
connect to give the ‘backbone’ of the DNA
strand before the daughter strands wind up
into a double helix
Homologous pairs
DNA Replication
