It synthesizes proteins and lipids, and puts them in vesicles and sends it to where it has to go
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:
The bottom of the cleft is in the palm domain. It is lined with beta sheet.
Explanation:
During DNA synthesis, a single DNA strand is being built in by polymerization of nucleotides. These polymerization process is catalyzed by enzymes called DNA polymerase. These DNA polymerase can be visualized as an open right hand which is composed of a thumb domain, a finger domain and a palm domain. The palm domain contains a prominent beta-sheet that forms a plate at the button of the DNA-binding cleft.
Answer:
Darwin's greatest contribution to science is that he completed the Copernican Revolution by drawing out for biology the notion of nature as a system of matter in motion governed by natural laws. With Darwin's discovery of natural selection, the origin and adaptations of organisms were brought into the realm of science.
