Hydrogen Bonds
Phosphate groups
The sequence of nitrogen bases
The sequence of deoxyribose sugars
Which statement correctly explains how information is
organized inside the DNA molecule?
Proteins are assembled based on the sugar-phosphate backbone of the DNA.
The way the DNA folds determine what proteins are made.
The instructions on how to make proteins are located in a segment of DNA called genes.
Each nucleotides contain the full instructions to create proteins.
Select the three reasons why cells have to go through mitosis. SELECT THREE
It helps produces ATP energy.
It helps create new cells for tissue layers.
It provides new cells for growth and development
It builds protein that is critical for body function.
It replaces old and damaged cells with the identical new ones.
Based on this diagram, multicellular organism help perform which function?
grow in total mass and height.
replaces dead and damaged cells.
develop into a mature organism
produces genetically identical offspring
Jon is a 8 month old baby, in the next year, he will grow, add more muscles, and bone cells. Which division is responsible for this type of growth?
Mitosis
Meiosis
All cells have identical DNA. Which of the statement is true.
They are formed from the same tissue layer within a mother's body.
They are produced from stem cells.
They are produced from a single cell that divided to produce more cells.
They are formed during meiosis that results in genetically identical cells.
Which statements are true regarding the relationship between DNA, genes, proteins, and genetic traits? Select three.
Proteins are built by using energy that the DNA molecule provides.
Genes provide instructions that determine how proteins are formed.
DNA molecules contain specific segments of information that are called
genes.
Genetic traits are determined by specific protein sequences on the DNA molecule.
Cells contain genetic information in the form of DNA that determines which traits are expressed in individuals.
What is a gene?
The total number of chromosomes in an organism.
A particular segment of DNA that is found in the chromosome.
The rounded protein where DNA coils itself around.
A single base pair of Adenine (A) and Thymine (T)
Which statement best explains why muscle and liver cells possess the same DNA but perform different functions and have different appearances?
Different cells express different genes in the DNA.
The cells are making different proteins by using the same genes.
There is a mutation in each of the cell.
Specific segments of the cell's DNA have been removed for each cell type.
Analyze the image above and select the statement that best describes what occurs.
During Mitosis, homologous chromosomes go through one round of cell division to create identical cells with half the number of chromosomes as the parent.
During meiosis, four new gametes are produced, each one will be different from the parent cell they came from because they replicate their DNA after they have divided.
During crossing over, pairs of sister chromatids exchange genetic information before being separated by two rounds of cell division, leading to genetically diverse gametes.
During crossing over, pairs of homologous chromosomes exchange genetic information before being separated by two rounds of cell division, leading to genetically diverse gametes.
What is the event happening this picture?
pairing of homologous chromosomes
separation of sister chromatids
chromatin condensing into chromosomes
crossing over between two homologous chromosomes.
What is the purpose of meiosis?
Helps with genetic variation and making us unique.
Helps with growth and development.
Helps with repairing of damaged tissues and organs.
Helps with replacing dead cells.
During the process of DNA replication, a copy of the DNA molecule is made. If the original strand has the sequence: ATT TTT TAG GGA, what will the newly formed strand of DNA be?
TAA AAA ATC CCT
UAA AAA AUC CCU

TAT GGG CTA TTC
If a strand of DNA reads: TAC TTA TCC, what will an mRNA copy of this sequence be?
ATG AAT AGG

UAG UUA UGG
AUG AAU AGG
If an mRNA sequence reads: AUG GGC UUA, what was the original DNA sequence?
TTC CCG TTA
TAC CCG AAT

AGU
Which statement is true regarding mitosis?
Each daughter cell receives either a full set of DNA from mom or DNA from dad but not both.
Each daughter cell has twice as much DNA as the parent cell because DNA doubles during prophase.
The parent cell passes identical genetic material to both daughter cells.
The daughter cells only have half the number of chromosomes because of anaphase.
