DNA sequencing of the human genome revealed that about ______ of the human genome encodes protein.Multiple choice question.10.2%1.5%5%6.5%

Break Down the Problem

1. Identify the key information needed to answer the question regarding the percentage of the human genome that encodes protein.
2. Analyze the multiple-choice options provided.

Relevant Concepts

• The percentage of the human genome that actually encodes proteins is known through genomic studies. This information is a fundamental concept in genetics and genomics.

Analysis and Detail

1. Research has shown that approximately 1.5% of the human genome consists of coding regions that encode proteins. This portion is known as "exons," part of the genes that are translated into proteins.

2. The remaining segments of the genome include intronic regions (non-coding parts of genes), regulatory elements, repetitive sequences, and non-coding RNA, which do not produce proteins.

Verify and Summarize

• Of the provided options:
  1. 10.2%
  2. 1.5%
  3. 5%
  4. 6.5%

The correct answer is 1.5%, as it aligns with current scientific consensus on the proportion of the human genome that encodes protein.

Final Answer

1.5% of the human genome encodes protein.
