Câu hỏi về DNA và Gen

Coding DNA refers specifically to:

• DNA segments that regulate gene expression

• DNA sequences that spontaneously mutate

• DNA sequences that directly encode proteins

• DNA sequences that move within the genome

De novo mutations are best described as:

• Newly arising mutations not present in parental genomes

• DNA sequences that code for proteins

• DNA segments that regulate gene expression

• DNA sequences that repeat multiple times

RNA transcriptome is defined as:

• DNA segments that code for proteins

• DNA sequences that move within the genome

• DNA sequences that spontaneously mutate

• All RNA transcripts produced by a genome

Copy number variations (CNVs) are defined as:

• Variations in the number of copies of specific DNA segments among individuals

• DNA sequences that spontaneously mutate

• DNA segments that code for proteins

• DNA sequences that repeat multiple times

What is a De novo mutation?

• DNA sequences that repeat multiple times

• A new genetic mutation occurring spontaneously, not inherited from parents

• DNA sequences that move within the genome

• DNA segments that regulate gene expression

What is Coding DNA?

• DNA sequences that move within the genome

• DNA sequences that repeat multiple times

• DNA segments that regulate gene expression

What is the Exome?

• DNA sequences that move within the genome

• DNA segments that regulate gene expression

• The portion of the genome consisting of all protein-coding exons

• DNA sequences that repeat multiple times

Epigenetics specifically refers to:

• DNA sequences that spontaneously mutate

• DNA segments that regulate gene expression

• DNA sequences that move within the genome

• Heritable modifications affecting gene expression without DNA sequence changes

What are Single Nucleotide Polymorphisms (SNPs)?

• Large DNA segments that move within the genome

• DNA sequences that repeat multiple times

• DNA segments that regulate gene expression

• Variations at a single nucleotide position in DNA among individuals

The Exome specifically refers to:

• DNA sequences that spontaneously mutate

• DNA segments that regulate gene expression

• All exons within the genome that code for proteins
