Shleiden and Theodor Schwann were the first to recognize that all plants and animals are composed of cells.
Hope this helped :)
Answer:
Conjugative Pili
Explanation:
Conjugative Pilli:allows for the transfer of DNA between bacteria, in the process of bacterial conjugation.
Answer:
Option (1), (2) and (3).
Explanation:
DNA is the genetic material of all the living organisms present on earth. The DNA contains the nitrogenous bases, pentose sugar and the phosphate group. DNA strands runs in the opposite direction and shows polarity.
Watson and Crick explain the structure of DNA based on the X ray diffraction produced by Rosalind. According to the structure, chromosomes are present in the nucleus and contains the DNA and wrapped around the proteins. The genes is considered as the functional segment of DNA.
Thus, the correct answer is option (1), (2) and (3).
the mitochondrion is where it takes place
well both are considered macromolecules. proteins are like big lego construction. each single piece gets pieced together to make a larger thing. each single piece is a monomer, and the larger construction is the polymer. the monomers are called amino acids and they get pieced together to form the polymer which is called a protein. the linkage that they use is an amide bond, and in biology it is usually called a peptide bond. carbohydrates can be singular monomers or polymer units. they are made of completely different compounds usually aldehydes or ketones. and they link together through different chemical linkages (acetal or ketal linkages for polymers, hemiacetal or hemiketal linkages for monomers). both can be large, 3D strucutres proteins are only functional as a large, 3D structure, while carbohydrates can be singular. (you might wanna word it differently for safety reason)
