Answer:
Mutations in DNA
An offspring receives half of its genetic material from its mother and half from its father.
Explanation:
Nucleotides are the building blocks ofnucleic acids; they are composed of three subunit molecules: anitrogenous base, a five-carbon sugar (ribose or deoxyribose), and at least one phosphate group.
The two tiny structures located in the cytoplasm near the nuclear envelope at the beginning of prophase are called <u>centrioles.</u>
Answer:
Arp2/3 and formins differ in their mechanisms of actin polymerization
Explanation:
The actin cytoskeleton plays key roles in diverse cellular processes including, among others, morphogenesis and endocytosis. The Arp2/3 complex and formin family proteins are two different types of actin-binding proteins capable of modulating the dynamics of actin filaments. The Arp2/3 complex is well known to have a key role in spine morphogenesis by promoting the branching of existing actin filaments. On the other hand, formin proteins induce the formation of plasma membrane protrusions by promoting the formation of unbranched filaments.
