Meiosis
Which statement is true of meiosis?
Organisms use meiosis to make reproductive cells.
Why is DNA replication considered a semi-conservative process?
The new DNA molecules contain one strand of the original molecule and one new strand.
What does mRNA do
moves genetic information from the nucleus to the ribosome
What amino acid sequence would be produced from the DNA sequence TAC CCC GCA AGT
Methionine - Glycine - Arginine - Serine
A mutation in which cell can create a change in heritable traits?
Gamete Cell
Which is a result of the replication of DNA during meiosis?
formation of sister chromatids
Which statement correctly describes the relationship between genes, proteins, and traits?
Genes are transcribed into mRNA. The mRNA is then translated into proteins, which determine specific trait
Which process produces mRNA from DNA?
Transcription
In which area of the cell does the interaction between codon and anticodon occur?
Ribosome
A strand of DNA with the sequence GAA CCG GGG undergoes a mutation, and the first G is changed to an A. How will this mutation affect the amino acid sequence?
One amino acid will change.
How are daughter cells different than parent cells in Meiosis
Daughter cells are genetically different from parent cells.
Which correctly matches a strand of DNA with its complementary strand of RNA?
DNA: ATA CCG
RNA: UAU GGC
Which RNA sequence will result from the transcription of the DNA sequence AAT TTC CGA ATG GGA?
UUA AAG GCU UAC CCU
Which molecules are joined together to make proteins?
Amino Acidss
Which process can occur in both mitosis and meiosis?
Gene mutations
Crossing over between chromosomes occurs during which phase of meiosis?
prophase I
Which of these shows the correct order for the central dogma of molecular biology?
DNA to RNA to protein
Which is not a step in protein synthesis?
DNA polymerase reads the mRNA
During translation, what does the tRNA deliver to the ribosomes?
AMINO ACIDS
What is Inversion
When they flip
How are mitosis and meiosis similar?
DNA replication
How is a segment of DNA copied to produce a molecule of mRNA?
through transcription
Dr. Tanaka discovered a new virus. The virus has a single strand of a nucleic acid, but she does not know if it is DNA or RNA. After running tests, she concludes that it is DNA. Which of the following would lead her to that conclusion?
IT Contains Thymine
Which statement best explains how mutations change the shape of flu virus antigens, preventing the attachment of antibodies?
Mutations change the nucleotide sequence of the gene, resulting in a different arrangement of amino acids.
