Central Dogma/Protein Synthesis

Question 1

DNA molecule consists of:

Answer 1

a deoxyribose sugar, a phosphate group, and a nitrogenous base.

Question 2

Go over DNA replication

Answer 2

During DNA replication, the DNA molecule separates into two strands, and then produces two new complementary strands following the rule of base pairing (A-T, C-G).
Each strand of the double helix of DNA serves as a template, or model, for the new strand. Thus, new DNA strands are considered to be semiconservative, half original. DNA and half new DNA. DNA polymerase is the enzyme that joins individual nucleotides to produce a DNA molecule (polymer).

Question 3

What are the 3 main types of RNA?

Answer 3

messenger (mRNA), transfer (tRNA), and ribosomal (rRNA).

Question 4

DNA has:

Answer 4

-double helix
-thymine
-Deoxyribose (sugar)
-STAYS IN THE NUCLEUS

Question 5

RNA has:

Answer 5

-single strand
-uracil
-ribose
-travels through cytoplasm to ribosome

Question 6

An RNA molecule consists of:

Answer 6

a ribose sugar, a phosphate group, and a nitrogenous base

(remember, RNA has NO thymine)
