A. All of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids. The amount of DNA in the cell has doubled
What is the S phase
100
Messenger RNA
What is the way information for a specific protein is carried on a DNA molecule?
What is the structure in DNA represented by the letters ATGC?
100
Codons
What is each sequence of 3 nitrogen bases that help determine the amino acids needed to make specific proteins?
200
G1, S, and G2. G1- the cell makes a variety of proteins needed to replicate DNA. S- the cell replicates DNA, and after replication the chromosomes now consist of two chromatids, or sister cells.
What is the three stages of interphase
200
Hydrogen bonds
What is the bond that holds together nitrogen bases?
200
Process by which mRNA is produced
What is transcription

Bonus
What is bonus!
300
The cells replicate their DNA, and grow so that they can make new cells. Which makes tissues.
What is mitosis
300
Double helix.
What is the scientific term for a DNA strand?
300
tRNA
What is the supplier of the instructions
300
They help the DNA to replicate and carry out the DNA functions.
What is the importance of proteins to a cell?
300
The codon in RNA
What is the way DNA in cells determine an organism's complex traits?
400
A.Prophase- DNA condenses into chromosomes. Spindle fibers branch out attaching to one chromatid. Centrioles move to opposite sides of the cell. Metaphase- nuclear envelope breaks down, DNA is lined up in the middle of the cell. Anaphase- sister chromatids separate at the centromere. Sister chromatids are now called chromosomes. They move to the opposite side of each spindle. Telophase- chromosomes uncoil, the mass of uncoiled chromosomes is called chromatin. Nuclear envelopes form around each cluster. The spindle fibers break down and disappear. The cytoplasm divides into two, and the cycle starts over.
5. Provide pictures of cells in each phase of mitosis.
What is mitosis?
400
The codons in RNA
What is the way that DNA in cells determines complex traits?
400
Complimentary strand to- C G T A G C
What is G C A T C G
400
You match the nitrogen bases with their pairs following the rule that A=T and G=C.
What is the way to determine the complementary strand of DNA?
400
The cell grows, gets nutrients for mitosis, replicates DNA, and prepares for division.
What is interphase
500
Where a cell is dividing to form two new cells.
What is cell division
500
Nitrogen bases.
What is the structure in DNA that allows different traits based on the order?
500
Serves as a temporary copy of DNA
What does mRNA do
500
DNA is shaped like a twisted ladder.
What is the thing that Rosalind Franklin discovered about DNA?
500
RNA- single stranded. DNA- double stranded
ribose. deoxyribose
uracil. thymine
