Which of the following statements is TRUE of microsatellites in the genome? Select ALL that apply. Occurs due to slippage during DNA replication. Occurs about 1x10^5 times in the human genome. Occurs about 3x10^4 times in the human genome. Typically range in length from 10 to 40 bps per repeat. They are made up of [CA]n or [CAG]n or [CGG]n.

Which of the following is TRUE for U1-U6 snRNPs in the spliceosome complex? Select one: a. None of the answer options are correct. b. Hydroxyl groups at the 2′ and 3′ positions of snRNAs are key reaction participants. c. U1-U6 snRNAs base-pair with the conserved sequences in the intron. d. All of the answer options are correct. e. Proteins associated with U1-U6 snRNPs form protein-protein interactions that position the splice donor and acceptor sites for two transesterification reactions.

Which of the below is true about aerobic cellular respiration? All of these It oxidizes carbon compounds and reduces oxygen It is endergonic It is an anabolic process It includes the Calvin Cycle and Glycolysis Does the average mutation rate in humans accurately describe the pattern of mutations across the genome? Yes. The mutation rate is the same between males and females. No. Mutation rates vary with geographic location – they are higher in some parts of the world than...

QUESTION 2 Which of the following is TRUE regarding the possible interbreeding between the human and Neanderthal species? a. A limited amount of variation has been passed from Homo neanderthalensis to Eurasian populations of Homo sapiens as a result of interbreeding that probably took place in the Near East at some point within the past 100,000 years. b. There is no evidence of hybridization between Neanderthals and modern humans. Both bone mtDNA and genomics studies ruled out such interbreeding. C....

A cell's genome is its blueprint for life. However, what is the bare minimum number of genes needed to sustain a free-living cell? This is a question that microbiologists at the J. Craig Venter Institute (JCVI) have attempted to answer ever since they sequenced the genomes of several Mycoplasma species in the 1990s. Because Mycoplasma species are parasitic bacteria, their genomes are already reduced in size and hence provide an excellent foundation for creating a "minimal cell." However, little did...
