Chapter 18, Problem 10A
Summary Introduction
Introduction:
Precambrian is one of the longest in duration with about 87% of the total time analysis. It is a chronological time scale which classifies the various organisms according to their features like seeded plants, vascular plants and ferns like conifers and cycads. It depicts the classification of the reptiles and amphibians with their classification. The time scale is divided into era, epochs, and periods. The periods are classified as primary, secondary, tertiary and quaternary.

Students have asked these similar questions
a) Find a nitrogen base. What carbon is the base attached to?
b) What two nitrogenous bases are held together by 2 hydrogen bonds?
c)What two nitrogenous bases are held together by 3 hydrogen bonds?
You will be building a double-stranded DNA molecule, representing a short (20 base) sequence that could be found in a chromosome. It will have a 3' --> 5' strand and a 5' --> 3' strand.
Use two full 12-base-pair DNA models.
a) Upload a photo of a model once the first 6 nucleotides have been inserted to base pair with the two parent strands.
b)Upload a photo of DNA polymerase I and Ligase in "action" removing the RNA primer nucleotides and making new phosphodiester bonds.
c)Upload a photo of the final two DNA strands, after Termination, identifying the parent and daughter strands of each.
Write down the 12 base-pairs (ex A-T or G-C) contained in the two models you will us from top to bottom below
Model 1 bp:
Model 2 bp:
