| Question | Answer |
|---|---|
| homozygous dominant | 2 dominant alleles (TT) |
| Homozygous recessive | 2 recessive alleles (tt) |
| heterozygous Dominant | 1 dominant, 1 recessive allele (Tt) |
| chromosomes | 23 pair |
| autosomes | 22 |
| chromosomes | 1 |
| codominance | occurs when the allelesare equally expresses in a heterozygote |
| incomplete dominance | occurs when the heterozygote is intermediate between the 2 homozygotes |
| deoxyribonucleic acid | found in chromosomes, located in nucleus |
| nuclear DNA | replicate |
| nucleotides | molecule comosed of 3 subunits |
| complimentary paied bases | a(adenine) pairs with T(thymine); G(guanine)pairs with C(cytosine) |
| messenger RNA | carries genetic info from DNA to the ribosomes |
| ribosomal RNA | joins with protiens made in the cytoplasm to form the subunits of ribosomes. |
| ransfer RNA | transfers amino acids to the ribosomes |
| transcription | DNA serves as a template; RNA polymerase opens up DNA to make complimentary base pairs |
| translation | required for protien synthesis; tRNA molecules bring amino acids to the ribosomes |
| replication | when cells divide; rarely a peplication error occurs |
