Answer:
both strands of the parent molecule act as templates
Explanation:
The process of DNA replication uses the existing parental DNA strands as a template. The enzyme helicase breakdown the hydrogen bonds between the base pairs of a DNA duplex to separate the two strands from each other. Each of these two DNA strands from a DNA duplex serves as a template for the process of DNA replication. Primase enzyme synthesizes primers on both the template strands which in turn are elongated by DNA polymerase enzyme.
Answer:
Sporophytes were branched before the evolution of vascular tissues
In early land plants the gametophytes were branched and complex like the sporophytes
Explanation:
The fossil record shows that early land plants appeared in the Ordovician Period, approximately 470 million years ago (Mya). These plants were non-vascular plants (e.g., mosses and liverworts) which can be recognized as fossilized spores. Thus, the first land plants could not transport nutrients like sugar, water, or minerals around the plant. Nowadays, it is believed that early land plants had gametophyte dominant life cycles (haploid life phase), while vascular tissues evolved as an adaptation to life on land, in the sporophyte (diploid life phase).
Answer:
The first answer and if more than one, the second. But health insurance does NOT cover all medical emergencies.
C, hydrogen bonds , i did this test last year and im in chemistry now, so its hydrogen bonds.
