Science Vocabulary All of Unit D

sorry really late need to study really tired from basketball don't blame me if i messed up on stuff all of unit D some stuff are represented by lines because if I wrote it.. it would sound really perverted (;-_-)

Terms

undefined, object
copy deck
o____
bottom part of the pistil that contains the ovules or immature seeds
genotype
an organism's genetic makeup or allele combination
homozygous
having two identical allele for a trait
allele
different forms for the same genes
stigma
upper tip of the pistil of the flower receives the pollen
meiosis
the process that occur in a s__ cell (______ and egg) by which the number of chromosomes are reduced in half
random
by chance, like the flip of a coin
Codon
the three letter code of bases on the messenger RNA that codes for one amino acid
DNA nitrogen bases
the chemicals that make up the rungs of the DNA ladder A-T and C-G match A-adenine G-guanine C-cytosine T-thymine
Anti-codon
the three letter code of bases on the transfer RNA that matched up with the codon on the messenger RNA
pedigree
a chart or "family tree" that tracks which members of a family have a particular trait
diversity
A wide variety of traits that are expressed in living things primarily due to reproduction
genetics
the scientific study of variation and heredity
mutation
Types include substitution,duplication, insertion, and deletion of chromosomes can be caused by: environmental agents (e.g the sun) mistake during DNA replication
phenotype
an organism's physical appearence or visible trait
MRNA
RNA that copies the code message from the DNA in toe nucleus and carries the message in the cytoplasm
style
narrow elongated part of the pistil between the ovary and the stigma
offspring
product of reproduction, a new organism produced by one or more parents
characteristics
A physical attribute of an organism such as hair color, height, color pattern ect.
s reproduction
the reproductive process that involves two parents who combine their genetic material to produce a new organism in which differs from both parents
a reproduction
the reproductive process involves only one parent and produces offspring that are identical to the parents( you all know what I mean)
TRNA
Carries amino acids and adds them to the growing protein at the ribosome
genes
a segment of DNA on a chromosome that codes for a specific trait
pistil
female reproductive part of a flower
Amino-acid
The building blocks of proteins; 1 codon= 1 amino acid; 100s to 1000s amino acids = 1 protein ;1 gene = 1 protein
heterozygous
having two different alleles for a trait
stamen
male reproductive part of a flower
mitosis
cell division creates two daughter cells identical to the original parent cell
clone
an organism that is genetically identical to the organism from which it is produced
heredity
the passing of traits from parents to offspring
probability
the likelihood that a particular event will occur
chromosomes
rod shaped cellular structure made of condensed chromatin DNA condensed into chromosomes just before cell division
"nature vs. nurture"
The debate regarding how much influence GENES and the Environment have on an individuals traits
incomplete dominance
a pattern of inheritance when the combination of a recessive allele and dominant allele (heterozygous) is expressed as a blend of the two traits (Ex. R=red, r=white, Rr=pink)
fertilization
the joining of a s____ cell and an egg cell
traits
a specific variation of a characteristic that an organism can pass on to it's offspring through it's genes
recessive
an allele that is masked when a dominant allele is present
inherited
transmitted through genes from parents to offspring
anther
the upper part of the stamen where the pollen is produced
co-dominance
A pattern of inheritance when two alleles of a gene are neither dominant or recessive, the two alleles are both expressed (Ex. B=black feathers b= white feathers Bb= black and white feathers)
filament
stalk like part of the stamen that supports the anther
