Answer: The complimentary strand will read ATG CCC GTC GTA TTT TAG
Explanation:
The complimentary strand to the replicating DNA molecule is known as messenger RNA (mRNA).
The mRNA directs specific bases to pair the existing base on the replicating DNA strand:
- Adenine (A) pairs only with Thymine (T)
- Guanine (G) pairs only with Cytosine (C)
So, to obtain the complimentary strand of TAC GGG CAG CAT AAA ATC, substitute each letter with its base pair.
Thus, the complimentary strand will read ATG CCC GTC GTA TTT TAG
Answer:
<u>d. Transport proteins within the membrane serve as a tunnel for molecules to enter the cell.
</u>
<u />
Explanation:
Solutes are typically moved across the cell through either passive or active transport. The cells, surrounded by a bilipid layer or plasma membrane is amphiphlic- its polar, hydrophilic lipid heads face outwards, while their non-polar hydrophobic lipid tails face inwards towards each other.
While lipid-soluble molecules move across the layer easily, it is also difficult for charged and also large molecules to move across its surface, into the cell. Transmembrane channels, <u>embedded within the membrane</u>, help to maintain selective permeability as transport proteins, pores and gated channels. Simple diffusion happens as a method of passive transport in cells through plasma membranes.
The solutes travel through the plasma membrane in the process of diffusion from regions of high concentration to regions of low concentration; this occurs without the use of energy. <u>Molecules moving against their concentration require active transport mechanism to cross the membrane</u>.
Answer:
The node
Explanation:
Each branch point on the cladogram represents where species split off into new ones. The node represents the last point at which 2 new species shared a common ancestor.
B. The amount of waste would build up and the toxins produced would harm the animals and humans
