Using a molecular clock, scientists are able to estimate the amount of time that two species have been evolving independently.
Hope this helps :)
It must pass from the nucleus to the ribosomes, hope this helped!
Answer:
B. introns; exons
Explanation:
Related genes from different organism usually translate to proteins of indispensable functions. This means that the proteins must be similar in terms of amino acids produced. Therefore the coding region must be highly conserved. These can be found in the introns. Conversely, exons are not a part of the coding sequence and therefore not required for translation. These sequences may be less conserved.
Explanation:
Amylase, lipase, pepsin, trypsin
Help in digestion of food by catabolizing nutrients into monomeric units
Hemoglobin, albumin
Carry substances in the blood or lymph throughout the body
Actin, tubulin, keratin
Construct different structures, like the cytoskeleton
Insulin, thyroxine
Coordinate the activity of different body systems
Legume storage proteins, egg white (albumin) Provide nourishment in early development of the embryo and the seedling
