Question
In the study of _______, microRNAs have been either too abundant or less abundant in affected cells.

oncogene
proto-oncogene
Cancer terminology
The difference between benign and malignant tumors is:
Malignant tumors are life threatening and benign tumors are not.
Benign tumors spread more slowly.
Benign tumors are not contained.
Malignant tumors are not contained.
Cancer terminology
Genes that regulate cell numbers by inhibiting division are called:
Oncogenes
Tumor suppressor genes
Proto-oncogenes
Metastasis genes
Cancer regulation

a technology used to preserve DNA found at crime scenes
using mtDNA to generate a profile
DNA profile vocab
Clines are created when:

15%
85%
100%
HW equilibrium
Explanation / Answer
Q1:- Option A
Explanation:- In the study of Cancer microRNAs have been either too abundant or less abundant due to deregulation of miRNA genes.
Q2;- Option A
Explanation:-Gene activation is promoted by binding groups because the binding group eases transcription.
Q3:- Option B
Explanation :- The "backbone" of DNA is composed of deoxyribose and phosphates
Q4:- Option C
Explanation:- Treatment for some genetic diseases as it is cure not treatment.
Q5:- Option D
Explanation:- Proto oncogenes promote regular cell division.
Q6:- Option A
Explanation:- Malignant tumours are life threatening as they show metastasis whereas as benign tumours are not.
Q7:- Option B
Explanation:- Tumor suppressor genes inhibit cell division.
Q8:- Option D
Explanation:- All of the above involves in genetic counselling.
Q9:- Option A
Explanation:- chromosomes other than sex chromosomes are called autosomes
