RSSSomatic cell
A somatic cell is generally
taken to mean any cell
forming the body of an
organism. Somatic cells, by
definition, are not germline
cells. In mammals, germline
cells are the sperm and ova
(also known as "gametes")

Chromosomal crossover
Homologous recombination is
the process by which two
chromosomes, paired up
during prophase 1 of
meiosis, exchange some
distal portion of their DNA.
Crossover occurs when two
chromosomes, normally two

Protein biosynthesis
Protein biosynthesis
(Synthesis) is the process
in which cells build
proteins. The term is
sometimes used to refer only
to protein translation but
more often it refers to a
multi-step process,

Trait (biology)
In biology, a trait or
character is a feature of an
organism. The term phenotype
is sometimes used as a
synonym for trait in common
use, but strictly speaking,
does not indicate the trait,
but the state of that trait

Introduction to genetics
Genetics is the study of how living things receive common traits from previous generations. These traits are described by the genetic information carried by a molecule called DNA. The instructions ... > more -
Cell (biology)
The cell is the structural and functional unit of all living organisms, and is sometimes called the "building block of life." Some organisms, such as bacteria, are unicellular, consisting of a single ... > more -

Morphogenesis is one of three fundamental aspects of developmental biology along with the control of cell growth and cellular differentiation. Morphogenesis is concerned with the shapes of tissues, ... > more -
Vector (biology)
Traditionally in medicine, a vector is an organism that does not cause disease itself but which spreads infection by conveying pathogens from one host to another. Species of mosquito, for example, ... > more -
Cell membrane
A cell membrane, plasma membrane or plasmalemma is a selectively permeable lipid bilayer coated by proteins which comprises the outer layer of a cell. The plasma membrane works between the machinery ... > more -
Prokaryote
Prokaryotes are organisms without a cell nucleus, or indeed any other membrane-bound organelles, in most cases unicellular (in rare cases, multicellular). This set of characteristics is distinct from ... > more -
