DNA and RNA structure
100

Helicase unzips the DNA. RNA Polymerase comes and starts coding mRNA. once mRNA is made then it leaves the Nucleus. 

What Step was just described? 

Transcription

100

How are DNA strands read? 

5' to 3'

100

During what phase does DNA replicate?

Interphase S-Phase

100

What is the cell type called when the cell has a specialized function?

differentiation cell

100

In DNA, what are the base pairing rules? 

A-T

C-G

200
mRNA finds a ribosome in the cytoplasm. The start codon calls for the first tRNA to bring Methionine to it. The tRNA will bond its anti-codon to the codon. The tRNA will wait for the next amino acid before leaving. The amino acids bond together with polypeptide bonds to start a protein chain. Soon the protein will form and leave the ribosome. 


What step was just described? 

Translation

200

Which enzyme separates the two DNA strands? 

Helicase

200

What are the reasons that cell division happens in multicellular organisms?

Growth Repair and Reproduction

200

What is a gene? 

A section of DNA that codes for a protein.

200

mRNA is made of codons that attract tRNA based on their what? 

anti-codon

300
Where does step 1 and step 2 take place

Transcription: In the nucleus

Translation: In a ribosome in the cytoplasm or the rough ER

300

What reads DNA strands to find its complimentary bases? 

DNA Polymerase

300

In RNA, A always pairs with ____? 

U 

Uracil 

300

What do proteins do? 

Determine traits like eye color

300

What is the backbone, legs, or rails of the DNA structure made up of? 

Phosphates and deoxyribose sugar

400

What type of functions do proteins have for the cell? Why are they important? 

Proteins are the main building block for how traits show up in organisms. 

Proteins are responsible for almost all functions of cell life. 

Proteins are the first to receive a signal from the environment and then communicate it to the cell membrane. 

400

True or false: After DNA replication is complete, there are two new DNA molecules; one molecule has both original strands and one molecule has two new strands of DNA. 

False

400

What are the three types of RNA?

mRNA, tRNA, rRNA
400

DNA replication uses existing DNA as a template to make new DNA. What is the vocabulary term? 

Semiconservative

400

What bonds A to T in DNA?

Double hydrogen bond

500

        OG: AGG GAU GCA

Mutation: AGG AAU GCA

What type of mutation is this? Use codon wheel 

OG: LYS VAL ALA

MUT: LYS  ASN ALA

Mutation: Missense (substitution)

500

What is the product of DNA replication? 

2 identical daughter strands

500

How is RNA different from DNA? 

RNA is single-stranded, uses Uracil, and has ribose sugar. 

500

One of two or more versions of a genetic sequence at a particular region on a chromosome. An individual inherits two {Blank} for each gene, one from each biological  parent.

Allele

What bonds C to G

A triple Hydrogen bond
