Answer: If a mutation occurred in Silencer of Death Domain (SODD) that prohibited its interaction with the DD of TNF receptor, the TNF receptor would evoke its response by binding to a transmembrane receptor, TNFR1.
Explanation: Binding to TNFR1 inhibits the recruitment of cytoplasmic signaling proteins to TNFR1 to prevent recruitment of a number of protein (TRADD) or prevent spontaneous aggregation of the cytoplasmic death domains of TNFR1 molecules.
SODD mechanism is useful in preventing unwarranted TNFR1 activation in the process of apoptosis.
<span>Natural selection is when species learn to adapt to
their environment. They could (1) differential reproduction, that is, not all
organisms are able to reproduce to their fullest capacity because nature cannot
simply sustain it and (2) acquire genes, that is heredity. Certain
characteristics of organisms tend to survive if it continues to strive. If it
survives, this trait is passed down to the next generations forgetting the
other traits but only the one who could survive the environment. Therefore it
is true that <span>natural
selection is when ‘organisms inherit advantageous traits, and tend to reproduce
more successfully than other organisms’. One best example is the extinction of
other animals and some with the same species retains.</span></span>
The primary difficulty is the fact that we do not know all of the organisms that currently exist in the world along with those that existed in the past.
Explanation:
Cell wall is not present in animal cells .
<span>At the end of prophase , nuclear membrane , nucleolus and all the cell organelles disappears and there is no distinction between the nucleoplasm and cytoplasm</span>
