The cell needs to carry out transcription before it can begin translation because transcription is the first step of gene expression, whereby the segments of DNA is copied into RNA in other words mRNA by enzymes RNA polymerase.
Both RNA and DNA are nucleic acids and they use base pairs of nucleotides as complementary language. It is during transcription when DNA sequence is read by an RNA polymerase which produces antiparallel RNA, complementary strand called primary transcript.
Transcription unit is the stretch of DNA which is transcribed into an RNA molecule and it encodes a protein then the transcription produces messenger RNA or mRNA the mRNA serves as a template for synthesis of proteins through the process of translation.
The transcribed gene may encode for either ribosomal RNA or rRNA, non-coding RNA for example microRNA. RNA performs a fundamental role in functions within a cell whereby it helps to regulate, synthesize, and process proteins.<span>

Answer:
The correct answer is a. Restoration ecology
Explanation:
Restoration ecology was coined by John Aber and William Jordan in late 1980. Restoration ecology is the study of rehabilitation, recreation, restoration of a degraded and destroyed ecosystem. This restoration is achieved by human intervention.
The different projects in this study included many different points like removal of non-native species, control of erosion, reforestation, re-vegetation, rehabilitation of native plants and animal species, etc.
Restoration ecology is important to control rapid environmental change and extinction of ecologically important species. So the right answer is a.
Answer:
Seminal vesicles
Explanation:
The seminal vesicles also called vesicular glands are found only in some mammals. Those are paired tubular glands within the pelvis with the function to secrete fluid that will become the semen.
Male cat does not have a seminal vesicle, but do have other accessory glands that secrete the seminal fluid such as prostate gland and Cowper´s (bulbourethral) glands.
