Semiconservative replication implies that: Group of answer choices each of the new double stranded DNA molecules contains one of
the original intact strands and one completely new strand. one of the new double stranded DNA molecules contains both of the original strands, while the other contains two new strands. each of the new double stranded DNA molecules contains strands that are composed of segments of original and newly synthesized material. None of these.
The correct answer is A) each of the new double stranded DNA molecules contains one of the original intact strands and one completely new strand.
Explanation:
<u>Semiconservative</u> is one of three types of replication. This particular one takes one original strand from the mother and creates the other one based on the original as a template. When one of the two new chains contains only original material and the other one contains only new material it's called <u>conservative</u> replication. When each strand preserves fragments from the original and creates fragments of new material it's called <u>dispersive</u> replication.
What role do transcription factors play in gene structure and function?
Transcription factors are proteins that bind to the upstream regulatory elements of genes in the promoter and enhancer regions of DNA and stimulate or inhibit gene expression and protein synthesis. They play critical roles in embryogenesis and development
