Q

Genotype

A

expression of genes on a minute scale

what they are

25
Q

Proteins

A

combinations of amino acids, what DNA codes for

expressions of genes assembling amino acid by using DNA template

26
Q

PMAT

A

Prophase: chromosomes become visible, nuclear envelope disappears

Metaphase: chromosomes line up on the equator

Anaphase: spindle fibers shorten separating chromosomes at the centromere pulling them to separate poles

Telophase: separate nuclear envelope

27
Q

Chromatin

A

nuclear material beginning to condense into chromosomes

28
Q

Dominant

A

gene that will express in heterozygous form

29
Q

Incomplete dominance

A

usually involves partial expression or mixing of heterozygous genes

30
Q

Monohybrid

A

looking at the possibility of one gene expression from 2 parents

31
Q

A, T, C, G, U

A

Nitrogenous bases of DNA/RNA

32
Q

cytokinesis

A

separation of daughter cells after mitosis

33
Q

Sister chromatids

A

copies of each other connected with a centromere

34
Q

recessive

A

gene that does not express in heterozygous form

35
Q

double helix

A

twisted ladder structure of the DNA molecule

36
Q

locus

A

a specific spot on the DNA molecule

37
Q

mitochondria

A

site of ATP synthesis for cellular respiration

38
Q

enzyme used to dissolve pectin in fruit and release more juice from the cell

41
Q

emporase or renin

A

enzyme we used in making cheese

42
Q

crossing-over

A

“leggy” chromosomes share genetic information making hybrid chromosomes

43
Q

sister chromatids

A

copies of chromosomes attached at centromere

44
Q

carrier

A

mutated gene that only expresses in homozygous conditions if you have one gene you are a carrier but its not expressed

45
Q

codominance

A

condition in heterzygous conditions results in both genes expressing e.g. blood type in humans SB

46
Q

DNA

A

deoxyribose nucleic acid

47
Q

independent assortment

A

chromosomes all go into separate gametes during meiosis

48

locus

A

a spot or nucleotide on a chromosome

49

pairs of chromosomes that come from different parents. These will never be connected by centromeres

50
Q

centromere

A

area where sister chromatids are attached

51
Q

TLC

A

thin layer chromatography - our photosynthesis lab

group of 4 chromosomes consisting of one from each parent (2) that have replicated after S phase (4)

58
Q

protease

A

enzyme that encourages DNA replication in PCR (polymerase chain reaction)
