DNA framshifts are caused by (adding) or (removing) DNA. Frameshifts are usually not good for an organism and leads to death. Every amino acid brought by before the mutation will be good but after deleting or removing DNA every made after is incorrect. So an incorrect protein is made.

null

Drugi mogući odgovor:

deleting

amino acid

tRNA

inserting

The following shows...

Substitution of the wrong base into the DNA code

Insertion of an extra base into the DNA code

Deletion of a base from the DNA code

Pitanje 5

5.

The image below shows the mutation known as "". In this type of mutation an is added to the DNA code. The extra base added in this example is .

null

Drugi mogući odgovor:

DNA substition

diatom

thymine

uracil

cytosine

extra base

DNA insertion

adenine

guanine

Pitanje 6

6.

The type of mutation seen below is a . The reason why is because a DNA base was from the DNA sequence. The DNA then shifts in the frame.

null

Drugi mogući odgovor:

removed

DNA insertion

added

DNA substitution

DNA deletion

DNA substitution mutation where an inappropriate base is placed into the DNA.

translocation in a chromosome.

a silent mutation.

Pitanje 10

10.

Select all of the options that can undergo mutations.

animals

bacteria

plants

viruses

fungi

Pitanje 12

12.

Silent mutations can have a neutral effect. Which of these is an example of a silent mutation

mRNA codon is mutated from GCU to UCU and instead of adding an alanine, a serine is added instead.

mRNA codon is mutated from AUU to AUG and instead of adding a leucine a mehtionine is added instead.

mRNA codon is mutated from AUU to AUC but both codons code for isleucine so the mutation is not a problem.

Pitanje 13

13.

Word bank: helpful harmful yellow love random

Mutations can be or helpful. All mutations are .

Pitanje 14

14.

What are some external and internal factors that can cause mutations.

A chemical that causes a mutation on someones skin

An event that messes up DNA replication and or protein synthesis during interphase

Radiation can cause mutations from exposure.

Pitanje 15

Word bank: traits proteins genes

DNA makes up . Genes code for . Proteins influence different

Pitanje 16

16.

When a gene or peice of DNA is mutated, this can effect the _________ made, which effects the organisms traits.

proteins

sugars

lipids

bilayers

time

Pitanje 17

17.

Substitution means...

a base was deleted from the DNA or RNA code

a base was added to the DNA or RNA code

a base was

the wrong base is matched

Pitanje 18

18.

Insertion is when...

the wrong bases are matched.

bases are switched in the DNA code.

an extra base or bases are added into the DNA code.

a base or bases are added into the DNA code.

Pitanje 19

19.

A deletion is when..

bases are flipped.

an extra base or bases are added into a DNA sequence

the bases are matched incorrectly in the DNA code.

a base or bases are removed from the DNA sequence.

Pitanje 20

20.

Which of these types of mutaions have the potential to be very dangerous?

Substitution mutation

Insertion mutation

Deletion mutation

Silent mutation

Pitanje 21

21.

Bases are read in

three's

fives

two's

fours

Pitanje 22

22.

Since DNA is read in threes. Inserting (insertions) or removing a base (deletions) could effect

the energy of the base

everything after it

nothing, the mutation would be silent
