What else can I help you with?
Are genes molecules or not?
Genes are not molecules themselves. They are segments of DNA that serve as instructions for making proteins. However, genes are encoded within molecules called DNA, which is a large, complex molecule that carries genetic information.
What is DNA cloning?
DNA cloning is the production of large number of identical DNA molecules from a single ancestral DNA molecule. It is of two types 1. cell based DNA cloning 2. cell free DNA cloning
How are large DNA molecules cut up?
Large DNA molecules can be cut up using enzymes called restriction endonucleases, which recognize specific short DNA sequences and cleave the DNA at those sites. These cuts result in fragments of DNA that can be separated by size using techniques like gel electrophoresis. This process is commonly used in molecular biology to study and manipulate DNA.
What substance has large molecules of smaller units?
Polymers are substances that have large molecules made up of repeating units called monomers. Examples include plastics, DNA, proteins, and carbohydrates.
What are large complex molecules formed by joining together many smaller molecules include?
Large complex molecules formed by joining together many smaller molecules include proteins, nucleic acids (DNA and RNA), polysaccharides, and lipids. These macromolecules play crucial roles in biological functions such as cell structure, energy storage, and genetic information storage.
What is ligase?
Ligase is an enzyme that catalyzes the joining of two molecules by forming a bond between them. It plays a crucial role in DNA replication, repair, and recombination by sealing breaks in the backbone of DNA strands. It can be used in molecular biology research to "glue" DNA fragments together during cloning and sequencing processes.
Whiat covalently connects segments of DNA?
Ligase covalently connects segments of DNA. It catalyses the joining of two large molecules by forming a new chemical bond.
DNA replications begins in areas of DNA molecules called what?
DNA replication begins in areas of DNA molecules are called origins of replication.
What makes of the sides of the ladder of a DNA molecule?
The sides of the DNA ladder are alternating deoxyribose (sugar) molecules and phosphate molecules. The DNA bases attach to the sugar molecules.
What molecules are found in chromosomes?
DNA molecules.
What is the spherical membrane-bound structure that contains DNA?
The nucleus.In a eukaryotic cell, the nucleus is more or less spherical, and surrounded by a double membrane perforated by pores that allow large molecules through. Inside the nucleus are the chromosomes, each of which has either one or (after DNA replication) two molecules of DNA.
Which relatively weak type of bond help stabilize did three dimensional structure of large molecules?
Hydrogen bonds help stabilize the three-dimensional structure of large molecules by forming between polar molecules, such as water, and within molecules, such as in protein and DNA structures. These interactions are important for maintaining the structure and function of biological molecules.
