The basic steps of a DNA ladder are made up of nucleotids
Answer:
The inheritance of mitochondrial DNA (mtDNA) is matrilineal, it means that an organism inherits the mtDNA from its mother
Explanation:
The phenomenon of matrilineal inheritance has deep genetic implications since it enables the study of phylogenetic lineages of the species (or among populations within the same species) by analyzing mitochondrial inheritance.
Answer:
Facilitated diffusion
Explanation:
Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient.
Facilitated diffusion is a passive transport process because they only depend on electrochemical gradients, so they do not need any energy to occur.
