The complementary DNA sequence for CTG GAA CTA is GAC CTT GAT. This is explained by the default base pairing of adenine (A) to thymine (T) and guanine (G) to cytosine (C) in double stranded DNA. This base paring is significant in DNA replication as well as in transcription of DNA but with the thymine (T) replaced by uracil (U) in RNA.
The answer is condensation
Answer:
Homologous structures
Explanation:
Homologous structures are structures (i.e skeletal elements) that come from the same common ancestor but they appear in the descendants of the ancestor with some modifications, normally due to different functions.
The wing of bats, flippers of whales or dolphins and the forelimbs of horses is a common example of homologous structures. Bats, whales and horses are vertebrates and all came from the same vertebrate common ancestor.
The common ancestor of these organisms had the bones that make up these structures, but through evolution those bones that make up the homologous structure were modified to serve different functions. They were modified for the flight in bats, for swimming in whales and for life on land in horses.
The driving force of photosynthesis is the energy that is contained in sunlight. This energy is transformed to energy that plants and other organisms use to live.
Answer:
Selective transport enables the substances to move rapidly through the cell membrane (for instance, H2O, O2 and CO2), while other substances pass through the cell membrane more slowly. Moreover, there are also compounds that can't pass through this barrier.
Explanation:
The selective transport of the substances across the cell membrane enables the cell to maintain the homeostasis of the system by maintaining the ionic equilibrium on both sides of the cell membrane. Moreover, selective transport also is required for carrying out cellular mechanisms, since this mechanism enables the entry and the exit of macromolecules used by the cell to maintain its function and structure.
The most common mechanisms of selective transport are diffusion and transport active. Endocytosis and exocytosis are active transport process where proteins, lipids, and different types of macromolecules are transported to both sides of the cell membrane through vesicles. Polar molecules (such as for instance, calcium and iron ions) may be transported via transport active, while hormones and vitamins may be transported via passive diffusion.
