<h3>What are fossils traces?</h3>
A fossil expresses the traces or is the remains of a prehistoric plant or animal that has died and its body part has been carefully been imprinted onto the surface of the rock that is sedentary as they have the characteristics of the mineral preserving qualities.
Their age, method of formation and evolutionary significance can be well established by the fossil remain in rocks that depict their occurrence throughout the carbon dating of the rocks.
The process that leads to the formation of fossil is Personalization, casts and moulds, recrystallization and Carbonization. Tracing a fossil consists of digging out the track and burrows.
Some fossil is found in deposits of resins which completely preserve the fossils from the erosion process.

Answer:
genes are the basic sequence of DNA that controls the traits of an organisms.
Explanation:
genes have nucleotide sequences. these sequences are involved in transmission of characters from one generation to other. if their is an error occur in this sequence the new offspring will b dissimilar from parent in this secific character which chnaged.
central dogma is the basic process through which genes are controlling the traits. first step is transcriotion through which DNA or gene is transcribed into mRNA sequence. then the second step is translation in which mRNA is translated into protein. in this way by making proteins genes control the traits or functiong of a body.
