Answer:

The correct answer is descent from a common ancestor.

Explanation:

Homologous structures are the structure which is similar in appearance but perform different functions in a different organism.

The wing of a bat, leg of an alligator and arm of a human, they all look similar in appearance with same type and number of bones but they all perform different functions in them.

The same type and number of bones show that they all have come from the same structure of the last common ancestor or their ancestor was common. This type of evolution is called divergence evolution and provides a piece of evidence to the theory of evolution given by Charles Darwin that "all species arises from same ancient common ancestor also called descent from a common ancestor". This proves that the evolutionary history of life forms a branching tree.

Thus, descent from a common ancestor is the correct answer.

Although a bat's wing, an alligator's leg and a human arm function differently, they all have similar structures in common. All have five digits and most likely the same number of bones within them.

This signifies that they all had similar origins in evolution.

Hope that helps!

Transcription chain elongation is thought to generate ____ supercoils ahead of the transcription bubble and _____ supercoils beh
frosja888 [35]

Answer:

a. positive; negative

Explanation:

Transcription is the process of forming an RNA molecule from a DNA template molecule. In this process, the strands of DNA separate and one serves as a template for RNA, while the other is inactive. At the end of the transcript, the tapes that have been split back together again.

The transcription process is divided into three steps: initiation, stretching and termination

During the stretching phase, transcription chain elongation occurs. In this phase the enzyme called RNA polymerase starts to move through the DNA molecule, unwinding its helix and producing an increasingly lengthened RNA molecule. The already transcribed DNA is rewound almost immediately, recomposing its double helix. This process is called the elongation phase.

During this process, it is believed that positive supercoils  are generated ahead of the transcription bubble and  and the negative supercoils behind it.

Which of the following statements correctly identifies the location of the hydrogens bonds in DNA
asambeis [7]

Answer:

This question is incomplete as it lacks options. However, it can be answered based on general knowledge of the DNA structure.

Hydrogen bonds in a DNA are located between the nucleotides that holds the double stranded DNA molecules.

Explanation:

Deoxyribonucleic acid (DNA) is the genetic material in living cells. The DNA molecule is made up of nucleotides monomers. However, since the DNA molecule is double-stranded, the nucleotides are of two chains composed of four nucleotide subunits viz: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).

The two chains of nucleotides in a DNA molecule are called strands. Each strand is bonded to one another by the nucleotides using complementary base pairing i.e. A-T, G-C. The bonds between the nucleotidew of each strand is called HYDROGEN BOND.

Hence, HYDROGEN BONDS in a DNA molecule is located in between two nucleotides of each strand. That is, hydrogen bond holds Adenine to Thymine and Guanine to Cytosine.
