Explain the role the following cellular components play in the storage, expression or transmission of genetic info. a)chromatin
|
genetically active spread out chrom. form of interphase. Chromatin cont. genetic material that is responsible for maintaining hereditary info and prod. of phenotype
|
|
|
Explain the role the following cellular components play in the storage, expression or transmission of genetic info. nucleolus
|
composed of ribosomal DNA and protein. structure that is prod. by the activity of the nucleolar organizer region in eukaryotes
|
|
|
Explain the role the following cellular components play in the storage, expression or transmission of genetic info. ribosome
|
struct. where various RNAs, enzymes and other molec. speceis assemble the primary seq. of a protein
|
|
|
Explain the role the following cellular components play in the storage, expression or transmission of genetic info. mitochondrion
|
mitochondrion is a memb. bound struct located in the cytoplasm of eukaryotic cells. Production of large amnt of ATP
|
|
|
Explain the role the following cellular components play in the storage, expression or transmission of genetic info. centriole
|
cytoplasmic structure involved in migration of chroms during mitosis and meiosis-- prim. in animal cells
|
|
|
Explain the role the following cellular components play in the storage, expression or transmission of genetic info. centromere
|
attatchment point for sister chromatids and a region where spindle fibers attch to chromosomes (kinetochore). Non disjunction can occur if spind. fibers or centromeres do not function properly
|
|
|
Chroms that are homologous share these properties...
|
overall length, pos. of centromere, banding patterns, type and location of genes, autoradiographic phase (tend to replicate during same time of S phase)
