How was Your DNAy? Come on, baby Do the Replication Hey babe, What’s YouR NAme? Teenage Mutant Ninja Turtles Express Yourself

Glucose is to glycogen, as ___________ is to DNA.

nucleotide

Specifically, what are the three parts to DNA nucleotide?

Deoxyribose, phosphate, nitrogenous base

Cytosine and Thymine have a single ring and are known as this.

pyramidine

The 5’ end and 3’ end refer to what part of the 5 carbon sugar?

Carbon 5 at top and carbon 3 at the bottom

These two scientists figured out that DNA carries genetic information, whereas proteins do not.

Hershey and Chase

Helicase breaks these bonds between these molecules.

Hydrogen, nitrogenous bases

This enzyme glues Okazaki fragments together.

Ligase

This enzyme lays down a short segment of RNA in order to start replication.

Primase

This term refers to how replication uses a template strand; and therefore, the new DNA consists of only one newly synthesized strand per double helix.

Semi- conservative

This enzyme digests and replaces the RNA primer with DNA

DNA Polymerase

These are the three kinds of RNA

mRNA, tRNA, rRNA

These two things are in RNA, but not DNA

Ribose, uracil

This molecule is made from DNA, and read by ribosomes.

mRNA

This is the anticodon of the tRNA that carries methionine.

UAC

From 5’ to 3’, what is the mRNA sequence that corresponds to the DNA strand: 5’ ATACCGAAT 3’

AUUCGGUAU (had to flip it!!!)

This is a change in the genetic code at a single nucleotide.

Point mutation

In thinking about protein synthesis, this is the least harmful point mutation.

Substitution

These three mutations involve chromosomal breakage.

Inversion, Deletion, translocation

If a cell was doubly fertilized (by two sperm), this would be the term to describe its chromosomes

Triploid, or polyploid

How are mutations linked to evolution?

Mutations are the ultimate source of genetic variation. If something is a beneficial mutation, it may increase over time in the population (change over time).

Define a gene.

A sequence of DNA that codes for a protein.

Which direction does the ribosome read mRNA?

5’  3’

List one of the many important job of these newly formed polypeptide chains.

Enzymes structures like in muscles, skin, etc. regulate cell cycle

When will protein synthesis occur?

When that protein is NEEDED.

When a genes is expressed, this means what two processes are occurring?

Transcription and translation
