Quaternary structure

I think I didn't put the word 'structure' and may have misspelt it 'quarternary'. Do you think it'll be all right?

Distance of the cell thing was 200 micro meters?

I think I did (6.6/1.6)x50= 206.25= 206 micrometer?

It should be;
First row :redface:

nly the first box because it had homologous chromosomes lining up in the centre
Second row: last two because they had only a single chromosme attached to each spindle fibre and not pairs
Hope it makes sense

I did that for the first row.

For the second row I ticked box 2 and box 3 - is this what you mean?

They should allow phonetic spellings - so yes.

Orgasmed over the 6maker, thought it was lovely. A lot of the one worded answers and one sentence answers were nice as expected, however thought the data analysis again to be a bit crap.

The question about why is the DNA between 1 and 2 arb units?

Odd number of chromosomes/ species is infertile? I dunno

I put the cells are undergoing DNA replication. Thoughts?

What is a phylogenetic group????????? Is it evolutionary relationships?????

Posted from TSR Mobile

I just put sth like... It shows the relationships between different species that are genetically related.

But I suspect 'evolutionary' is the key word here for at least one of the marks so I must've dropped that. Thought that was too obvious for one to state. blimey ...
