Knowing the sequence of an organism's DNA allows researchers to study specific genes, to compare them with the genes of other organisms, and to try to discover the functions of different genes and gene combinations.
Molecular techniques such as PCR (polymerase chain reaction) and DNA sequencing are necessary to identify plants that have integrated a transgene. These techniques allow researchers to specifically amplify and analyze the DNA sequence of the transgene in the plant's genome.

This field of study is called developmental biology. It aims to understand how organisms develop from a single cell into complex multicellular structures through processes like cell division, differentiation, and morphogenesis. Researchers in this field investigate genetic, molecular, and environmental factors that influence growth and development.
To identify the DNA sequence of every human gene, researchers typically use techniques such as whole-genome sequencing and RNA sequencing. These methods allow scientists to map and analyze the complete DNA sequence in the human genome and to understand which segments correspond to active genes. Additionally, bioinformatics tools are employed to annotate genes and predict their functions based on the sequenced data. The Human Genome Project was a landmark initiative that provided a comprehensive reference for human genes.

Some methods of biological investigations include microscopy, DNA sequencing, immunohistochemistry, and cell culture techniques. These methods allow researchers to study various aspects of living organisms, such as their structure, function, and interaction with the environment.
A light microscope allows scientists to view cells, tissues, and microorganisms at the cellular and subcellular level. This tool enables researchers to observe biological structures and processes in detail, aiding in their study of living organisms.
To locate the nucleotide sequence within a DNA or RNA sample, one can use a technique called DNA sequencing. This process involves determining the order of nucleotides in the sample, which can be done using various methods such as Sanger sequencing or next-generation sequencing technologies. These techniques allow researchers to read the sequence of nucleotides in the DNA or RNA sample, providing valuable information for genetic analysis and research.

Microscopes are essential tools in biology because they allow scientists to observe and study tiny structures and organisms that are not visible to the naked eye. This enables researchers to better understand the complexities of living organisms, study cellular structures, and make important discoveries in fields such as genetics, microbiology, and medicine.

A scientist studying how populations evolve would most likely observe organisms with short generation times, high reproductive rates, and large population sizes, such as bacteria or fruit flies. These organisms allow researchers to observe multiple generations quickly and see how genetic changes occur over time within a population.
