The f1 generation may have genes for short plants just that the genes for long plants are dominant over the genes for short plants(recessive) so when cross pollination happen and that two f1 long plants which are homozygous cross pollinate, the recessive genes have a chance of being paired up in new offspring(F2 offspring) thus the possiblity of short plants in f2 generation

PLEASE HELP!! im despratte
Alex73 [517]

Answer:

Template strand = complementary strand

GCA AG = CGT TC

TTA CG = AAT GC

GAT AC = CTA TG

CGG AT = GCC TA

DNA strand = mRNA strand

CGA TT = GCU AA

GCT TA = CGA AU

GCA TC = CGU AG

TTC AT = AAG UA

It is more important for DNA replication to be exact than transcription or translation because any error that occurs during DNA replication if not repaired will become permanent and will be transferred to the next generation.

Explanation: In DNA base pairing, G pairs with C and T pairs with A. But in RNA base pairing, G pairs with C and U pairs with A. DNA contains four bases G, C, T and A while RNA contains four bases G, C, A and U.
