hello
fossils, the preserved remains of animal and plant life, are mostly found embedded in sedimentary rocks. Of the sedimentary rocks, most fossils occur in shale, limestone and sandstone. Earth contains three types of rocks: metamorphic, igneous and sedimentary.
Have a goed day
1) Some alleles are dominant and some are recessive. Principle of Dominance.
2) Genes passed down from parent to offspring. ...
3) During the production of gametes, two copies of each hereditary factor separate.
4) Genes for different traits can segregate independently during the formation of gametes.
Hope this helps! :)
Answer:
(1)sequence of bases in DNA
Explanation:
Because it from there codons are obtained to then form amino acids to then make protein, which are like building blocks in a person
Its false because it takes a while for the gases to deteriorate the atmosphere <span />
Answer:
Explanation:
The unicellular organisms basically classified into prokaryotes and eukaryotes. In case of bacteria the nucleus was completely absent but the replication and translation process were combined together. so there is no need of complexity. The genome is under control of one replication of origin i.e. the replication of DNA and translation for proteins synthesis takes place simultaneously and again no complexity. The organism is depend on these proteins and DNA for different purposes like fission, energy production etc.
If we think about Eukaryotes there is separate boundary for DNA and protein synthesis Nucleus and rest of cytoplasm with organelles. The complexity increases because of functional variations and functions occur at different times. So the whole genome replication is not needed every time and there are separate Origin of replications for segments of DNA (genes). Along with these there are non-functional DNA segments (introns functionally they won’t give proteins). To eliminate them there is a separate process after mRNA synthesis called post transcriptional modifications. After this protein synthesis takes place at cytoplasm. There is one more check point called post translation modification where protein modification (functional diversity) allocated. To adapt the changing environment, stress, reproduce and for any functions there is a wide diversity if we compare prokaryotes and eukaryotes.
