Whereas the nucleotide strand used for transcription is termed the ___________________ , the nontranscribed strand is called the _______________ template strand; nontemplate strand In transcription, nucleotides are always added to the ___________ end of the elongating strand. 3' In eukaryotes, RNA polymerase ________ transcribes the genes that encode

Variation is a characteristic that can be inherited. Every organism group overproduces offspring leading to a struggle for survival. Individuals with favorable characteristics are more likely to survive, passing their genes leads to evolution. - ️️Theory of organic evolution by natural selection The male semen was only formed from the blood ~ provides "form" The female menstrual blood contains the "matter" The "form" controls and shapes the "matter" into mature ...
