2. What is a feature of transcription? * 1 point Both strands of a DNA molecule act as a template for mRNA. Nucleoside triphosphates become nucleotides by losing three phosphates. RNA polymerase binds to the promoter region. The sense strand acts as a template for mRNA.

The correct answer is ''RNA polymerase binds to the promoter region. ''

Explanation:

The process of DNA transcription is the first step towards the formation of proteins from DNA. DNA transcription is the synthesis of mRNA (messenger RNA) from DNA that will later be translated to form proteins. RNA polymerase must recognize the starting point of synthesis. This area of DNA, described as a promoter, consists of two short sequences of bases located 10 and 35 base pairs from the initial point of synthesis. By convention, to describe the region of DNA where the gene to be transcribed is located, the number +1 is given to the base pair (DNA) where RNA synthesis begins, up to + n, which will be the last base pair where synthesis ends. RNA polymerase is the enzyme that transcribes the sense strand of DNA into a messenger RNA molecule. This enzyme forms the phosphodiester bond in growing RNA by nucleophilic attack on the incoming nucleotide. It does not need a primer and synthesizes in the 5′-3 ′ direction.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
