Question
Chapter 21.4, Problem 12LO
Summary Introduction
To explain: The function of lymph nodes.
Concept introduction: Lymphatic system consists of a network of vessels, tissues, and ducts that carry a clear fluid (lymph) to all body parts. The lymph nodes are the secondary lymphoid organs present in the immune system. The lymph nodes are small glands that are situated throughout the body and are linked with the help of lymphatic vessels.

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:
