46, XX 16

In X chromosome inactivation, all of X chromosome genes are inactivated.

False

What disease is caused by a mutation in ATM gene

Reciprocal translocation

Where is DNA methylation most often in the gene?

in CG

What can be a reason behind autoimmune disease being more prevalent in women?

X inactivation

True for CpG dinucleotides

The methylation in pro,other region provides a basic regulation of gene expression

An enzyme that adds a methyl group to a substrate

methyltransferase

DNA methylation

it refers the methylation of cytosine base by the DNA methyl transferase

less off target initiations from that gene

miRNA in mammals mostly acts by

cleaving target mRNA

A frameshift mutation has more serious consequences than a point mutation

Causesallofthecodonsafterittobedifferent

mitochondrial disease

heteroplasmy

The short arm of Acrocentric chromosomes consist mainly of a satellite and thin stalk, containing multiple copies of genes encoding ribosomal RNAs.

true

Repeat core sequences consisting of 2,3,4 base pairs in one pseudogene are known as

microsatellites

Which molecule plays a role in spermatogenesis in transposons silencing?

piRNA

These are molecular mechanisms that mediate epigenetic phenomena, EXCEPT:

deamination

An interstitial deletion of paternal chromosome subregion 15q11-q13 results Prader-Willi syndrome (PWS). The deletion of the same subregion of maternal chromosome results another disease Angelman syndrome.
