Variation, DNA and meiosis

?
variation can occur due to
genetic factors
1 of 23
a measure of spread
standard deviation
2 of 23
deoxyribonucleic acid
dna
3 of 23
a sugar, a phosphate, an organic base
neucleotide
4 of 23
A and T are
complementary base pairs
5 of 23
2 words to describe the structure of DNA
double helix
6 of 23
what type of reaction binds base pairs
condensation
7 of 23
bond between the strands of DNA
hydrogen
8 of 23
a section of DNA that codes for a polypeptide
gene
9 of 23
how many amino acids are there
twenty
10 of 23
there are 3 bases that code for amino acids, this code is called
the triplet code
11 of 23
we call the triplet code a
degenerate code
12 of 23
the amino acid that ends the polypeptide chain is called
stop code
13 of 23
DNA combines with proteins and forms a DNA-protein complex. Coils form, loop and pack together to form a
chromosome
14 of 23
chromosome pairs are known as
homologous
15 of 23
how many chromosomes do humans have
fortysix
16 of 23
the total number of chromosomes is referred to as
diploid
17 of 23
in gametes the number of chromosomes is referred to as
haploid
18 of 23
the forms of genes are known as
alleles
19 of 23
the process of the reproduction of gametes
meiosis
20 of 23
how many divisions are in meiosis
two
21 of 23
the position of a gene on a chromosome
locus
22 of 23
chromatids twist around each other and break a portion of the chromatids. the portions are exchanged and bind to the oppersite chomatid. this is known as
genetic recombination
