Scientists are now studying human DNA in labs all over the world. Which are current goals for the scientists at these labs? Select three answers that apply. A. completing a full sequence of human DNA (the Human Genome Project) B. identifying the regions of human DNA that are transcribed into RNA C. identifying the regions of human DNA that bind to proteins D. analyzing the regions of human DNA that vary among individuals E. describing the molecular structure of human DNA

Answers

Answer:

B. identifying the regions of human DNA that are transcribed into RNA

C. identifying the regions of human DNA that bind to proteins

D. analyzing the regions of human DNA that vary among individuals

Explanation:

The double helix structure of the deoxyribonucleic acid (DNA) molecule was characterized and published in April 1953 by Francis Crick and James Watson. Moreover, the Human Genome Project was a project aimed at completing mapping and sequencing of the human genome. This project was completed and published in April 2003. Nowadays, scientists are focused on identifying which genes are expressed (i.e., transcribed into RNA) in specific cell types/tissues. For this purpose, it is imperative 1-to identify the promoter and enhancer regions that bind to specific proteins (transcription factors) in order to activate gene expression, and 2-to understand how genetic variation is related to gene expression patterns in specific cell types and/or in response to specific environmental stimuli.

The majority of states give the state legislature main power over the process of drawing congressional and state legislative districts. Thus, option B is correct.

What gerrymandering shaped North Carolina's?

The admittance of Dakota Territory as two states rather than one is a remarkable example. Regardless of its population, each new state carried a minimum of three electoral votes under the standards for representation in the Electoral College.

On February 11, 1812, the first “gerrymander” was sketched on a map and made official. The redistricting plan was approved by Elbridge Gerry, the governor of Massachusetts at the time, in order to maintain his party's hold on power in the forthcoming election.

Therefore, gerrymandering shape of North Carolina's Twelfth Congressional District.

Consider the diagram of the basic structure of a bacterium. A diagram of a bacterium is labeled. Part A is the cell membrane, part B is the flagellum, part C is the nucleoid, and part D is the pilus. Which of the labeled structures in the image allows bacteria to exchange genetic material and thus evolve to be better pathogens?

Answers

Answer:

Part D: pilus

Explanation:

Conjugative pili allow for the transfer of DNA between bacteria and thus evolve to be better pathogens.

The structure in bacteria that allows them to exchange genetic material and evolve is the pili
