New cards
Peptide bonds form between the following groups
one amino group and one carboxyl group
2
New cards
The primary structure of a protein is
the amino acid sequence
3
New cards
The chromosome that determines human gender is
the Y chromosome
4
New cards
Every amino acid shares which characteristics
all of these
5
New cards
A mutation actually results from
a change in the nucleotide sequence
6
New cards
How many types of amino acids are coded by repeating UAs
three
7
New cards
Which of the following is NOT a component of the translation initiation complex
RNA polymerase enzyme
8
New cards
The tRNA molecule is called an adaptor molecule because
it binds to both DNA and an amino acid
9
New cards
Components needed for initiation and elongation of translation include
both ribosomal subunits tRNA with attached amino acids and mRNA
10
New cards
In the Watson-Crick model of DNA the polynucleotide chains are
oriented in opposite directions
11
New cards
The G1 phase represents
a period of growth
12
New cards
Diploid means having
two complete sets of chromosomes
13
New cards
Homologous chromosomes have
the same genes but can have different alleles
14
New cards
Mitotic cell division creates identical copies by replicating DNA
once twice
15
New cards
In mitosis the nuclear envelope begins to reform during
telophase
16
New cards
Apoptosis is also called
programmed cell death
17
New cards
Haploid gametes contain
half the 2n chromosome number
18
New cards
A cell that could not form spindle fibers could not perform
mitosis or meiosis
19
New cards
The first event in prophase of mitosis is
the chromosomes begin to condense
20
New cards
A cell in G0 state
has ceased growing and dividing
21
New cards
The largest part of the cell cycle is
interphase
22
New cards
During crossing over pieces exchanged are
a chromatid of the maternal chromosome and a chromatid of the paternal chromosome
23
New cards
The process of meiosis results in
a reduction in chromosome number
24
New cards
A cell condenses its DNA into
chromosomes
25
New cards
After meiosis I human germ cells have
haploid nuclei
26
New cards
Human DNA encodes
all answers are correct
27
New cards
The complementary DNA probe sequence for AATGCAGTACCGTA is
UUACGUCAUGGCAU
28
New cards
Sister chromatids align along center during
metaphase II
29
New cards
The enzyme used latest in DNA synthesis is
gyrase
30
New cards
The complement of 5 prime GTCAC 3 prime is
3 prime CAGTG 5 prime
31
New cards
The basic unit of a DNA molecule is
nucleotide
32
New cards
Sister chromatids are
genetically identical and attached to each other at the centromere
33
New cards
Homologous chromosomes contain the same genes but may contain different
alleles
34
New cards
The process exchanging genetic material between homologous chromosomes is called
crossing over
35
New cards
Recombinant chromosomes have a mix of maternal and paternal alleles due to
crossing over
36
New cards
Alternate forms of the same gene are called
alleles
37
New cards
A single chromosome has
a single gene with a single allele
38
New cards
At the beginning of meiosis II in a 2n equals 6 organism how many chromatids are present
6
39
New cards
During meiosis the centromeres divide at
anaphase II
40
New cards
What type of mutation always decreases gene length
deletion mutation
41
New cards
What type of mutation causes codons to be read out of sequence
frameshift mutation
