What is DNA

100

The genetic material provides this kind of information

What are the cell's growth and other activities

200

The genetic material is stored in this-DNA for short

What is deoxyribonucleic acid

300

DNA is like a book to the proteins because... 

What is it provides the instruction but the protein actually follows them

400

These are the people you inherit your characteristics from

What are your parents

Important People of DNA

100

Rosalind Franklin and Maurice Wilkins both made this major discovery

What are the images of DNA using x-rays

200

This person discovered the 4 different nucleotides. (Hint: His finding is known as Chargaff's Rules)

Who is Erwin Chargaff?

300

James Watson and Francis Crick used Chargaff's Rules and Franklin's and Wilkins' x-rays to make this major discovery.

What is to find that DNA looks like a long, twisted ladder?

400

These people discovered that DNA, not proteins, carries genetic information

Who are Alfred Hershey and Martha Chase

Mutations

100

This is what a mutation is

What is a change in number, type, or order of DNA

200

If a DNA strands order went AT, CG, AT, AT and after this kind of mutation, it went AT, CG, AT

What is deletion

300

If a DNA strand went GC, TA, AT, AT but after this kind of mutation it went GC, TA, AT, AT, CG

What is insertion?

400

If a DNA strand went AT, GC, CG, TA but after this mutation, it went AT, AT, CG, TA

What is substitution?

Punnet Squares

100

If a mother of an offspring is homozygous recessive for her blue eyes, and the father is heterozygous for his brown eyes, there is this much of a chance of blue eyes.  

What is 25%?

200

If a mother of an offspring is heterozygous for her brown hair and the father is also heterozygous for his brown hair there is this much of a chance for brown hair.

What is 75%?

300

If a mother of an offspring is heterozygous for her brown eyes and the father has blue eyes, these are the chances of the offspring having brown eyes?

What is 50%?

400

If the mother of an offspring is homozygous recessive for her blonde hair and the father is homozygous dominant for his brown hair this is how likely it is for the offspring to have blonde hair.

What is 0%?

Chromosomes and Alleles

100

This is how many chromosome pairs you get from each of your parents.

What are 23 pairs?

200

This is how many total numbers of chromosomes you get.

What is 46?

300

This is how many possible alleles there is for each gene.

What are 2 alleles?

400

A dominant allele is represented by a capital letter and this allele is represented by a lowercase letter.

What is a recessive allele?
