it looks right..cause the triplet given was the non-coding strand of DNA so the template strand of DNA would be ATT? then mRNA UAA and tRNA AUU :\ sorry if i dont help ><

I agree, their triplets are back to front, i got 5' UUA 3' for the mRNA

Although I'm notoriously bad at doing genetics in my head :P

Non-coding strand is the template strand which mRNA is complementary to...

template/non coding are synonymous and refer to the same strand of DNA...

QUESTION PLEASE

ok
so I know the ratio is 9:3:3:1 when 2 homozygous people have  a bang.

HOWEVER
when they linked
sometimes you see weird stuff like 3:1:1:3

why is this?

I hate these bloody evolution questions...

How do you do the one below for part d?

Also, what exactly is technological evolution and how is it affected by cultural evolution, which I understand to be 'the passing on of information.'

9: 3: 3: 1 applies for heterozygotes. When the genes are linked recombination accounts for the lower amounts, as it is usually that the recombinants in number are less than the non-recombinants.

I don't think so.

The wording was probably incorrect then, but the working was correct.

technology evolution is just basically the evolution and advancement of technology eg genetic engineering.
cultural evolution is new characteristicss that arent transmitted by genes more towards socialising and may or may not be affected by technology as u mentioned its just the passing on of information.
thats what i understand of it anyway
