All the following statements about microsatellite DNA are true except:
Select one:
a. It consists of a repeat length of 1–13 base pairs.
b. It can cause neurological diseases such as myotonic dystrophy.
c. It can occur within transcription units.
d. all of the above
Answer. All of the above
Justification
microsatellite DNA sequences are considered to have a length of 1-8 nucleotides. They do not cause any diseases, instead owing to their higher mutation rate, they causes high genetic diversity.

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 statements about mutations are true? Select all that apply. Select one or more: a. Both substitution and indel mutations could result in a non-sense mutation in the affected codon following the mutational event. b. Indel mutations that occurred in an exon (translated part of the gene) can be silent. c. A substitution mutation can lead to a frameshift. d. Mutations are the only source for the origin of new alleles. Consider the wild-type DNA sequence: 3'...
All of the following are true about the structure of deoxyribonucleic acid except _______ complementary base pairing between the nitrogenous bases from two strands of nucleotides forms the secondary structure of DNA a single nucleotide has a phosphate group, pentose sugar, and nitrogenous base. The primary structure of DNA consists of nitrogenous bases sticking out from the backbone phosphodiester bonds connect deoxyribonucelotides in the primary structure of DNA nucleotides consist of a phosphate group, pentose sugar, and nitrogenous base. The primary structure of DNA...
Identify the true statements about RNA interference. Select all of the true statements. Duplex RNA is cleaved by the Dicer enzyme complex. Duplex RNA (dsRNA) can suppress the expression of a gene. miRNAs are short, single-stranded RNA segments that are about 45 nucleotides long. RNA interference can temporarily suppress the expression of a target gene. miRNAs suppress gene expression by interfering with transcription.

All of the following are true about cellulose EXCEPT: (select all that apply, must have all correct for credit) a) it contains a microfibril structure due to hydrogen bonding between sugar residues in adjacent cellulose chains b) It consists of many glucose units connected by beta (1-6) linkages c) It is the main component of plant cell walls d) It is well fermented by colonic bacteria I think it is just B and D but not sure about the others.
