Where within DNA does STR analysis take its genetic information?
Group of answer choices
A:From the maternal chromosome.
B:From the coding region.
C:From the non-coding region.
D:From the paternal chromosome.
Answer: B : From the coding region
Explanation: STR (Short Tandem Repeat) analysis is used to check the repeating pattern on the coding region to compare between two chromosomes. It is used in the molecular biology particularly in forensic analysis.

Why would selection have favored ‘protocells’ that used DNA to store genetic information? Group of answer choices DNA is more stable and has a lower mutation rate. DNA can evolve more quickly Because DNA cannot catalyze reactions DNA viruses are less harmful than RNA viruses. DNA viruses are less harmful than RNA viruses.

Chromatin remodeling enzyme complexes ______. Choose all that apply. Group of answer choices: 1.cause DNA to be repositioned for access or tighter packing. 2.are non-histone proteins that can bind to the chromatin in interphase nucleus. 3.promote the transition from the 30nm fibre to the 11nm fibre. 4.are essential for regulating gene expression. 5.are able to bind to the chromatin structure anywhere and cause DNA within a nucleosome to be repositioned. 6.bind to chromatin by binding to chemical modifications in the...
1. DNA replication is considered semiconservative because Group of answer choices it will create three new, identical strands when finished. it never replicates in the 5 to 3 prime direction. it always replicates in the 3 to 5 prime direction. it uses the original strand as a template for replication. 2. Which is NOT true about the genetic code? Group of answer choices It produces 64 different possibilities of base sequences. It contains start and stop codons as instructions. It...
bio -> genetics **please explain answer You use PCR analysis on DNA from a couple and their developing fetus to screen for a genetic defect. You find that both parents have one large and two small DNA bands, while the fetus has only the large DNA band. The most likely explanation for these results is: Group of answer choices All three are heterozygotes Both parents are heterozygotes, the fetus is a homozygote you cannot tell the allele combinations for the...
