Basic Genetics

Gene Expression

TougherGenetics

Potpourri

This is the base that replaces thymine (T) in

mRNA.

What is uracil (U)?

This is the structure within the cell where

translation takes place.

What is the ribosome?

This is the enzyme responsible for attaching to the

promoter region and assembling the

messenger RNA strand.

What is RNA Polymerase?

The three nucleotide sequence read on the

mRNA is also known as this.

What is a codon?

This would be the complimentary mRNA code for the following

DNA sequence:

CGA ATT GTT CAC

What is:

GCU UAA CAA GUG

This is the combination of alleles an organism

inherits from its parents. (the genetic makeup)

What is the genotype?

This is the typical genotype of an

individual that is a carrier for a trait.

What is a heterozygote?

This is the genotype for the maternal parent in the

pedigree below assuming the trait is autosomal recessive.

What is homozygous dominant?

Colorblindness is an example of this type of

inherited disorder.

What is sex-linked (or X-linked)?

These are the possible blood type of offspring with parents who have genotypes of IAIB and

IAIB.

What are blood types A, B and AB?

This is the complete genetic material contained in an

individual.

What is the genome?

These are master switch genes that control the

development of an organism.

What are homeotic (homeobox or hox)

genes?

This is defined as uncontrolled cell growth

that can invade other parts of the body.

What is cancer?

These are genes that prevent cell division from happening too

frequently.

What are tumor supressors?

This is the type of mutation that occurs

when there is an addition of one or more nucleotides to a DNA

sequence.

What is an insertion mutation?

A couple has four children and each child

has a different ABO blood type, these would be the genotypes of the

parents.

What is, one parent is type A, IAi, and the other

is type B, IBi?

This type of gene mutation would not

result in a frameshift.

What is a substitution?

It’s in these types of cells where when

mutations occur they affect the offspring but

not the individual.

What are germ cells?

The table below lists observed values for a cross between green and yellow seeded plants. Two heterozygotes were crossed. Assuming green is dominant, these would be the expected results for green and yellow seeds.

SEED COLOR # OBSERVEDGreen 639Yellow 241

What is green expected is 660 and yellow is

220?

This would be the number of offspring in the following cross that would be carriers in a

cross between the parents XBXb and XBY.

What is 1 out of 4?

AKA the P generation.

What are the parents?

This is the type of cross where we examine two

traits.

What is a dihybrid cross?

This is the mRNA start codon for translation.

What is AUG?

The likely gender of this fine fruit fly…

http://en.wikipedia.org/wiki/Drosophila_melanogaster

What is male?

Below is an example of this type of

chromosome mutation.

What is an inversion mutation?
