2 strands linked via hydrogen bonds between nitrogenous bases.

Question 12

Who identified the double helix in the DNA

Answer 12

Double helix identified by Watson&Crick

Question 13

RNA is plain compared to DNA why?

Answer 13

Because it only contains a single-strand of molecule.

Question 14

DNA is found where in the cell?

Answer 14

Found, ONLY in nucleus of cells

Question 15

DNA controls heredity how?

Answer 15

It controls heredity by containing “instructions” for building proteins in an organism.

Question 16

RNA is found where in the cell?

Answer 16

Found in Cytoplasm and Nucleus of cells

Question 17

What part of RNA copies DNA

Answer 17

It copied DNA’s “instructions” to build proteins, it then takes them to Ribosome.

Question 18

What are the 3 parts of RNA? List and Descript’ (describe them)

Answer 18

mRNA: copies DNA’s “instructions” for building proteins, takes them to Ribosome. rRNA: site where instructions translated into protein. tRNA: brings specific amino acids to ribosome so properties can be made.
