Answer:
a. hox genes.
Explanation:
HOX genes have the following functions:
- HOX genes are the homeobox subset.
- They specify the areas of the embryo's body plan along the animal head-tail axis.
- They are encoding Hox proteins that specify the position characteristics and ensure that the right structures form at the right position in the body.
- They regulate high-level executive genes, such as transcription factors and intracellular signaling molecules, which adhere, number, form, and growth to cells.
The vertebrates are highly preserved.
The clusters and other genes occur uninterrupted.
Evolutionary, the heterogeneous regulatory areas between the genes most previously present are larger and more preserved than those present at the other ends of the clusters.
The characteristical feature is that these are homeodomain proteins with a highly preserved area of DNA binding encoded with homeobox gens.
Answer:
I think laboratory experiments
Explanation:
Answer:
Correct
Explanation:
It’s always more likely that the dominant gene will show than the recessive gene.
Answer:
1) Break down of the nuclear membrane allowing mitotic spindles to connect to kinetochores:A. Metaphase
2)APC degrades securin which allows separase to become active which degrades the cohesin rings: E. Anaphase
3) Dephosphorylation of nuclear pore and lamins: F.Telophase
4) cleavage of plasma membrane by actin and myosin contractile ring:D.Cytokinesis
5) copying of the genome:C. Interphase
6) formation of the metaphase plate:B. Prometaphase
Explanation:
Answer:
d
Explanation:
This leads to unnecessary replication and out-of-control cell and tissue growth
