The definition of Asexual Reproduction
Creating an offspring using one parent
The definition of Sexual Reproduction
Creating an offspring using 2 parents
How does RNA polymerase start transcription?
Before the coding gene, there is a region called the promoter sequence where RNA polymerase begins transcription; this is where the template strand is determined
Which type of letter represents a dominant trait and which type of letter represents a recessive trait?
Dominant (Capital letter) Recessive (Lowercase letter)
DNA stands for...
Deoxyribosenucleic Acid
A disadvantage of Asexual Reproduction
Lack of genetic diversity
Disadvantage of Sexual Reproduction
Slower process
What happens if a mutation occurs in the noncoding DNA?
It does not matter and wont affect our phenotypes
Chance of an outcome compared to total outcomes
What is probability
DNA's structure
Double Helix
Advantage of Asexual Reproduction
Faster process
Advantage of Sexual Reproduction
Increase of genetic diversity
List the functions of: tRNA, mRNa, rRNA
tRNA: brings correct amino acid to each of mRNA's codons
mRNA: temporary copy of DNA
rRNA: structural component of the ribosome where transcription takes place
Complete a punnet square with a pure recessive parent and a pure dominant parent.
DDdd etc etc
DNA's function is
Storing genetic information
List 5 types of Asexual Reproduction
Fragmentation
Vegetative Reproduction
Cloning
Budding
Parthenogenesis
Define the process of Sexual Reproduction
The process in which a gamete with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes.
how do introns get spliced?
snRNP’s are enzymes used to splice out introns. They recognize the splice sequences to cut
In pea plants, the trait for tall (T) is dominant over the trait for short (t) stems. Draw a punnet square for a hybrid parent reproducing with a pure recessive parent. If 250 pea plants were produced, how many would have short stems?
125 pea plants!
What is a common phrase said about DNA
"DNA is the blueprint of life"
Define Pathogenesis
the process by which an infection leads to disease. Pathogenic mechanisms of viral disease include (1) implantation of virus at the portal of entry, (2) local replication, (3) spread to target organs (disease sites), and (4) spread to sites of shedding of virus into the environment.
Define Meiosis
A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant s
True or False: Eukaryotes have more regulation when it comes to expressing their genes
TRUE
T - tall t - short Y- yellow y- green A plant that is TTYy would appear as: A plant that is Ttyy would appear as:
TTYy - Tall / Yellow Ttyy - Tall / Green
