Answer:
Microtubules, like actin filaments, are dynamic structures: they can grow and shrink quickly by the addition or removal of tubulin proteins. Also similar to actin filaments, microtubules have directionality, meaning that they have two ends that are structurally different from one another. I hope this helps :)
Answer:
Human diploid cells have 46 chromosomes
Explanation:
Answer:
5 bases
Explanation:
If there are 17 amino acids and only 2 bases that can be combined in order to make a codon then:
for 4 bases
is 16 and it is not enough combination for all 17 amino acids
for 5 bases
is 25 combinations (meaning that more than one codon could code for the same amino acid).
