Peptide bonds form between the following groups

one amino group and one carboxyl group

The primary structure of a protein is

the amino acid sequence

The chromosome that determines human gender is

the Y chromosome

Every amino acid shares which characteristics

all of these

A mutation actually results from

a change in the nucleotide sequence

How many types of amino acids are coded by repeating UAs

three

Which of the following is NOT a component of the translation initiation complex

RNA polymerase enzyme

The tRNA molecule is called an adaptor molecule because

it binds to both DNA and an amino acid

Components needed for initiation and elongation of translation include

both ribosomal subunits tRNA with attached amino acids and mRNA

In the Watson-Crick model of DNA the polynucleotide chains are

oriented in opposite directions

The G1 phase represents

a period of growth

Diploid means having

two complete sets of chromosomes

Homologous chromosomes have

the same genes but can have different alleles

Mitotic cell division creates identical copies by replicating DNA

once twice

In mitosis the nuclear envelope begins to reform during

telophase

Apoptosis is also called

programmed cell death

Haploid gametes contain

half the 2n chromosome number

A cell that could not form spindle fibers could not perform

mitosis or meiosis

The first event in prophase of mitosis is

the chromosomes begin to condense

A cell in G0 state

has ceased growing and dividing

The largest part of the cell cycle is

interphase

During crossing over pieces exchanged are

a chromatid of the maternal chromosome and a chromatid of the paternal chromosome

The process of meiosis results in

a reduction in chromosome number

A cell condenses its DNA into

chromosomes

After meiosis I human germ cells have

haploid nuclei

Human DNA encodes

all answers are correct

The complementary DNA probe sequence for AATGCAGTACCGTA is

UUACGUCAUGGCAU

Sister chromatids align along center during

metaphase II

The enzyme used latest in DNA synthesis is

gyrase

The complement of 5 prime GTCAC 3 prime is

3 prime CAGTG 5 prime

The basic unit of a DNA molecule is

nucleotide

Sister chromatids are

genetically identical and attached to each other at the centromere

Homologous chromosomes contain the same genes but may contain different

alleles

The process exchanging genetic material between homologous chromosomes is called

crossing over

Recombinant chromosomes have a mix of maternal and paternal alleles due to

crossing over

Alternate forms of the same gene are called

alleles

A single chromosome has

a single gene with a single allele

At the beginning of meiosis II in a 2n equals 6 organism how many chromatids are present

6

During meiosis the centromeres divide at

anaphase II

What type of mutation always decreases gene length

deletion mutation

What type of mutation causes codons to be read out of sequence

frameshift mutation
