DNA replication and Biomolecules

DNA replication and Biomolecules

Review for the unit quiz!

Multiple Choice

The four major types of biomolecules are:

• lipids, carbohydrates, nucleic acid, and proteins

• lipids, hormone, nucleic acid, and tissues

• starch, sugars, fats, and oils

• eeny, meeny, miny, & mo

Multiple Choice

In eukaryotic cells, DNA does all these things except (assume all others are true!)

• is mostly concentrated in the nucleus

• is tightly coiled into chromosomes

• passes on genetic information to new cells

• goes to ribosomes to make proteins

• does the process of replication during interphase of the cell cycle

More about biomolecules:

Biomolecules are polymers made by your body. They are composed of CHNOPS and have specific monomers that are their building blocks. Please check out the chart on the next slide and remember the monomers and an example of each type of biomolecule!

Multiple Choice

Watson and Crick are usually given credit for the "discovery" of DNA's structure. However, they used information from this scientist, even though they did not share credit when they received the Nobel Prize.

• Maurice Wilkins

• Carl Linnaeus

• Rosalind Franklin

• Charles Darwin

This situation reinforces that these things advance science:

• Scientists should share ideas

• Cooperation is important

• Failed investigations that rule out information are often just as important as correct information

Fill in the Blanks

Multiple Choice

The base pairs that form DNA are:

• adenine & thymine and cytosine & guanine

• adenine & cytosine and thymine & guanine

• adenine & uracil and cytosine & guanine

Multiple Choice

In eukaryotic cells, DNA does all these things except (assume all other options are true!)

• is concentrated in the nucleus

• is tightly coiled into chromosomes

• passes on genetic information to new cells

• leaves the nucleus, goes to ribosomes, & makes proteins

• replicates itself during interphase of the cell cycle

Multiple Choice

Each of your specialized cells has a different type of DNA

• true

• false

Every somatic cell in your body ...

• has exactly the same DNA strand

• different sections of DNA can be activated to produce specialized cells

Multiple Choice

The best way to raise my biology grade is to:

• complete missing work

• make sure my notebook is in order with notes from this activity and other lessons

• show up to class and be sure to complete the last quiz

• all of the above!

Multiple Choice

RNA is different from DNA because:

• it's a single strand that has uracil instead of thymine

• it's a single strand that has uracil instead of guanine

• it's a triple strand that has uracil instead of thymine
