Question

Please help i dont understand bio at all ill give medal

Answer 1

1. A mutation that causes changes in the amino acid sequence downstream of the mutation is called (1 point)
a point mutation.
a translocation mutation.
a substitution mutation.
a frameshift mutation.
2. What will be the outcome of deletion of the third base, A, from the DNA sequence below? Assume that the first base corresponds to the start of a codon. (1 pt) (original)
-C-C-A-A-A-T-A-A-A-G-
(1 point)
The first amino acid in this sequence does not change.
A frameshift mutation occurs.
Gly-leu-phe is changed to gly-tyr-phe.
All of the above are correct.

Answer 2

Yah sorry i forgot to put which ones they are here is what i think
b and d

Answer 3

@aaronq and @Frostbite can you guys help

Answer 4

nevermind i think they are d and d

Answer 5

yeah d for both make sense

Answer 6

thanks can u help with these two
3. What type of mutation is albinism? (1 point)
advantageous
lethal
neutral
deleterious
4. An original DNA sequence and a mutated form of this sequence are shown below. What type of mutation occurred?

Original: -G-C-T-T-A-G-T-C-C-A-G-T-A-
Mutation: - G-T-A-G-C-T-T-A-G-T-C-C-A-
(1 point)
translocation
insertion
deletion
inversion

Answer 7

I think the answers are d and d

Answer 8

im not sure how albinism works, but i would say it's pretty neutral, if you consider lacking pigment and more susceptible to sunburns n what not.. idk if it's deleterious.

the other one is translocation

Answer 9

i think albinism causes vision impairment, so i guess that makes it not neutral .. and it's definilty not advantageous, and not lethal... so yeah the only one left is deleterious

Answer 10

D D D A were indeed correct :)

Answer 11

thank you, lovelys(: i shall fan you, and medal.

Answer 12
