Answer:
Epigenetics.
Explanation:
Epigenetics is the study of phenotypic changes which are heritable but not related to changes in the DNA sequence. It is influenced by several factors including the environment.
An example of epigenetics is DNA methylation: addition of methyl group to some part of the DNA that prevents that part from being expressed. Other examples include history modifications.
In summary, Epigenetics describes inheritance through other mechanisms than through the DNA sequence.
The answer is missense. Hope this helps!
Answer:
The skeletal muscle fibres are of two types namely slow-twitch muscle fibres (type I muscle fibre) and fast-twitch muscle fibre (type II muscle fibre).
The slow fibres are slow contracting and help in developing endurance such as long distance running, maintaining posture etc whereas fast fibres are fast contracting and help in movements which require force such as sprinting etc.
Other differences are summarized in a tabular form attached below.
Amino acids make up proteins. ansd DNA is transcripted to make RNA which is transported to ribosomes out of the nucleus which then reads the codons to choose amino acids that combine to form a polypeptide chain. the polypeptide chain that's long enough will make a protein which gives you your traits
