Explain the Central Dogma .

Must go in order. DNA → mRNA → Proteins

Doesn't have to be in order. mRNA → Proteins → DNA

What are the steps for Protein Synthesis?

Replication → Transcription → Translation

Transcription→ Replication→ Translation

Translation → Transcription → Replication

Which are three reasons offspring may differ from their parents?

Crossing Over homologous chromosomes exchange pieces, causing variation in the final cells

Law of Segregation gametes are formed, alleles from one trait separate into different gametes.

Law of Independent Assortment states that the alleles of two or more different genes get sorted into gametes independently of one another

Law of Dominance Some traits are dominant. They can hid or mask other traits, while others are recessive, they can be masked or hidden

What is a Nondisjunction ?

Failure of chromosomes to separate during meiosis.

Occurs when a gene sequence is repeated

Chromosome segment breaks off Segment flips around backwards Segment reattaches

Changes in the nucleotide sequence of DNA

No changes in the nucleotide sequence of DNA

Which are PROS of Mutations?

A scorpion is given an extra stinger.

An albino tree frog can be easily seen among the green trees.

Which are CONS of Mutations?

An albino tree frog can be easily seen among the green trees.

A scorpion is given an extra stinger.

Which are Gene Mutations ?

Frameshift Inserting or deleting one or more nucleotides

Point Mutations Change of a singlenucleotide

Nondisjunction Failure of chromosomes to separate during meiosis.

Translocation Involves two chromosomes that aren’t homologous.

Which are Chromosomal Mutations ?

Inversion Segment flips around backwards.

Deletion A piece of a chromosome is lost.

Nondisjunction Failure of chromosomes to separate during meiosis.

Translocation Involves two chromosomes that aren’t homologous.

Duplication Occurs when a gene sequence is repeated.

How are stem cells used in biotechnology?

To generate virtually any type of specialized cell in the human body.

How are plasmids used to transform bacteria?

By cutting the gene of interest

organisms that containfunctional recombinant DNA

Which are some examples of how clones may be used in biotechnology?

To create identical cells for research purposes

To maintain a genetically desirable species of plant or animal

To create a missing organ or tissue for treatment of human diseases

To save endangered or extinct species

Which are the steps of how animals are cloned?

DNA is extracted from an adult cell

An egg for this same species has it’s DNA removed

The empty egg is filled with the adult DNA

The egg is implanted into a surrogate mother

The baby born from this egg is genetically identical to the adult from which it was cloned
