Biology Unit 4 test prep
During replication, which sequence of nucleotides would bond with the DNA sequence TATGA?
ATACT
How would the DNA sequence GCTATA be transcribed to mRNA?
CGAUAU
What is one difference between RNA and DNA?
RNA contains uracil instead of thymine.
When during the cell cycle is a cell's DNA replicated?
S phase
Which of the chains of amino acids corresponds to the nucleotide sequence UCAAGCGUA
Ser-Ser-Val
If one strand of DNA has the sequence of nitrogenous bases AACTG, its complementary strand has the sequence
TTGAC.
A set of three consecutive bases that specify an amino acid is called a(n)
codon
During translation, the type of amino acid that is added to the growing polypeptide depends on the
codon on the mRNA and the anticodon on the tRNA.
Which of the following does NOT describe the structure of DNA?
contains adenine-guanine pairs
DNA replication results in two DNA molecules,
each with one new strand and one original strand.
During normal mitotic cell division, a parent cell that has four chromosomes will produce two daughter cells, each containing
four chromosomes.
The function of the spindle is to
help separate the chromatids.
Which of the following is NOT an advantage of asexual reproduction?
increases genetic diversity
The period between cell divisions is called
interphase.
In eukaryotes, DNA
is located in the nucleus.
The complementary strand of RNA that is produced during transcription is called
mRNA
The two main stages of cell division are
mitosis and cytokinesis.
When during the cell cycle are chromosomes visible?
only during cell division
The two "backbones" of the DNA molecule consist of
phosphates and sugars.
All nucleotides contain each of the following EXCEPT a
protein.
In eukaryotes
transcription takes place in the nucleus and translation takes place in the cytoplasm.
The DNA that results from replication consists of
two molecules that each contain one new strand and one original strand.
The enzyme that joins individual nucleotides to produce a new strand of DNA is called
DNA polymerase.
The central dogma of molecular biology is that information is transferred from
DNA to RNA to proteins.
In eukaryotes, the spindle breaks down during prophase and reforms during telophase.
False
What happens during anaphase?
The sister chromatids separate.
Why are stem cells important?
They have the potential to develop into other cell types.
Transfer RNA is important in
adding amino acids to a polypeptide.
