Which of the following best describes a DNA molecule?

double helix

contains ribose

made of amino acids

contains Uracil

Which of the following units are repeatedly joined together to form a strand of DNA?

amino acids

nucleotides

fatty acids

polysaccharides

Why is DNA important?

it is very small and very complicated

it's in everything

it serves as the blueprint for traits of all living things

because we eat it every day for energy

Which 2 molecules form the sides (backbone) of the DNA ladder?

deoxyribose sugar and adenine

deoxyribose sugar and a hydrogen bond

deoxyribose sugar and the nucleus

deoxyribose sugar and phosphate

ATTTGAGCC- Original
ATTGAGCC - Mutated
The example above is an example of a

All of the above

Transcription is a process that in eukaryotic cells takes place in the:

Nucleus

Cytoplasm

Golgi Apparatus

Rough E.R.

Translation is a process in eurkaryotic cells takes place in the:

Cytoplasm

Nucleus

Nucleolus

Golgi Bodies

10.

What amino acid is represented by the codon UUA?

Phenylalanine

Tyrosine

Leucine

Stop codon

11.

In DNA replication, if the original sequence reads AATTTGCG, the complementary DNA strand would read?

AAUUUCGC

AATTTGCG

TTAAACGC

UUAAACGC

12.

What are the building blocks of proteins called?

DNA

RNA

Ribosomes

Amino Acids

13.

What term describes when mRNA is read 3 consecutive letters (bases) at a time and it codes for a single amino acid?

Codon

Anticodon

Polypeptide

Gene

14.

Which choice below correctly summarizes the base-pairing rules in RNA?

A-G

C-T

A-C

T-G

A-U

C-G

A-T

C-G

15.

How would the DNA sequence GCTATA be transcribed to mRNA?

GCUAUA

CGATAT

CGAUAU

GCUTUT

16.

If the mRNA codons read ACA-GUA-GAA-UUG-AUC, what amino acids make up the protein sequence?

Cys-Val-Gly-Ser-Stop

Cys-His-Leu-Asn-Stop

Thr-Val-Glu-Leu-Ile

None of the above

17.

Once the DNA is copied into RNA, it goes to what organelle to begin protein synthesis?

nucleus

rIbosome

cytoplasm

centriole

18.

DNA replication turns one strand of DNA into two new strands of DNA. What percent of each new strand is the old strand?

Half of each new DNA is the old DNA

The old strand of DNA was digested, so none

The new DNA is entirely made up of the old DNA

About every sixth base comes from the old DNA

19.

Sometimes, DNA is called "semi-conservative." Why might this be?

The old strand is "conserved" and used to make the new strands

Uracil is "conserved" in that it is only used to make the new strands

ATP is "conserved" via the usage of facilitated diffusion

Ligase is "conserved" in that it is denatured by the process

20.

Match he nucleotide with its complementary nucleotide. (DNA to DNA).

Cytosine-

Thymine

Guanine

Adenine

21.

Original DNA: CAT GAT CCA

New DNA: CAT TGA TCC A

substitution/point

inversion

insertion
