Explanation:
Nondisjunction: Failure of paired chromosomes to separate (to disjoin) during cell division, so that both chromosomes go to one daughter cell and none go to the other. Nondisjunction causes errors in chromosome number, such as trisomy 21 (Down syndrome) and monosomy X (Turner syndrome). It is also a common cause of early spontaneous abortions
Answer:
a plant hormone which promotes leaf detachment, induces seed and bud dormancy, and inhibits germination.
B is correct. A tendon will join a muscle to a bone, and a ligament joins a bone to another bone. I think of it this way, partly influenced by my biology teacher:
- The achilles tendon, at the back of your foot, clearly joins foot to calf muscle
- The word ligament comes from 'deligare' in Latin, which roughly means to tie together. A ligament 'ties' two bones together
I hope this helps
RNA has Uracil instead of Thymine. All the other three bases also occurs in RNA, adenine, guanine and cytosine. Therefore a ATA DNA codon will be transcript to UAU by RNA. Both Thymine and Uracil have the same role in however have minor chemical differences.
