new bottom strand

Here are the answers to this:

1. AUG - GGG - CCA- GUU -GAA- AAA - AUU- GCA - GAA - CUU - UGC

2. AUG - GGG - CCA - GUU - GAA - AAA - AUU - GCA - GAA - CUU - UGA

3. TAC - CCC - GGT - GAA - CTT - TTT - TAA - CGT - CTT - GAA - ACT

Here's something to remember:

The top strand is the coding strand, then the bottom serves as the template strand. So this is where the RNA will get the information. So we get the complementary strand first then match the RNA sequence.

DNA to complementary DNA strand

BASE PAIRING:

G ⇒ C ; C⇒G

A ⇒ T ; T⇒A

Complementary DNA to mRNA

BASE PAIRING:

G ⇒ C ; C⇒G

A ⇒ U ; T⇒A

The new Bottom strand

BASE PAIRING:

G ⇒ C ; C⇒G

A ⇒ T ; U⇒A

If you remember the base pairings, you might be able to do it on your own next time :)

ORIGINAL TOP STRAND

ATG - GGG - CCA - GTT - GAA - AAA - ATT - GCA - GAA -CTT- TGA

Get the complementary strand

TAC - CCC - GGT - CAA - CTT -  TTT  - TAA - CGT - CTT -GAA - ACG

Then you get the mRNA strand

AUG - GGG - CCA- GUU -GAA- AAA - AUU- GCA - GAA - CUU - UGC

ORIGINAL TOP STRAND

ATG – GGG – CCA – GTT – GAA – AAA – ATT – GCA – GAA – CTT – TGA  

Get the complementary strand

TAC - CCC - GGT - CAA - CTT - TTT - TAA - CGT - CTT - GAA - ACT

Then get the mRNA strand

AUG - GGG - CCA - GUU - GAA - AAA - AUU - GCA - GAA - CUU - UGA

New bottom strand

TAC - CCC - GGT - GAA - CTT - TTT - TAA - CGT - CTT - GAA - ACT

they deliver oxygen to the blood

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
