2.6 Structure of DNA and RNA

Question 1

4 complimentary base pairs

Answer 1

Adenine and Thymine(Uracil if RNA)

Guanine and Cytosine

Question 2

Complementary base pairs

Answer 2

the standard arrangement of bases in nucleotides in relation to their opposite pairing

Question 3

DNA polymerase

Answer 3

an enzyme that catalyses the elongation of new DNA during replication

Question 4

DNA

Answer 4

Deoxyribonucleic-acid consisting of two long chains of nucleotides twisted into a double helix that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA.

Question 5

Hydrogen bond

Answer 5

a chemical bond in which a hydrogen atom of one molecule is attracted to an electronegative atom of another molecule.

Question 6

Nucleic acids

Answer 6

biological molecules, such as DNA or RNA, composed of nucleotides that control cellular functions and heredity.

Question 7

Nucleotides

Answer 7

the building blocks of nucleic acids consisting of a five-carbon sugar, a nitrogenous base and a phosphate group.
-DNA and RNA are polymers of nucleotides

Question 8

Polymer

Answer 8

a large molecule consisting of many identical or similar monomers linked together

Question 9

RNA

Answer 9

a nucleic acid consisting of a long single-stranded chain of nucleotides involved in protein synthesis

Question 10

RNA polymerase

Answer 10

an enzyme that links together the growing chain of RNA during transcription

Question 11

Anti-parallel

Answer 11

two things which are parallel but go in opposite directions
