The laboratory procedure for copying selected segments of DNA is?
The laboratory procedure for copying selected segments of DNA is called polymerase chain reaction (PCR). In PCR, the DNA template is heated to separate the DNA strands, then specific primers are added to initiate replication by a DNA polymerase enzyme. The process is repeated multiple times to amplify the DNA segments of interest.
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 are nucleotide segments of DNA molecules that make up genes and are expressed in the phenotype of an organism?
Genes are nucleotide segments of DNA molecules that code for specific proteins or RNA molecules. These genes are transcribed into messenger RNA (mRNA), which is then translated into proteins that ultimately determine the organism's phenotype.
What is the relationship between chromosomes and genes and between genes and DNA?
Chromosomes are structures made of DNA that carry genes. Genes are segments of DNA that contain the instructions for making proteins. DNA is the molecule that carries the genetic information needed for the development, functioning, and reproduction of living organisms.
Which areas in the DNA contain repeated segments?
Repeated segments can be found in various regions of DNA, including telomeres, centromeres, and certain satellite DNA sequences. These repetitive elements are often involved in important cellular processes such as chromosome stability and gene regulation. Additionally, repeat expansions in certain regions of the genome are associated with genetic disorders.
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.

When scientist copy DNA they first have to cut out the part they wanted to copy what molecules do they use to do this this?
Restriction endonuclease.

What are needed to transfer a gene through a DNA molecule?
Genetics engineering is needed to transfer genes through DNA molecules.
Which enzyme is responsible for connecting the short segments of newly synthesized DNA segments?
DNA polymerase
What way can DNA segments be changed such that genes are altered or mutated?
DNA segments can be changed through a variety of mechanisms, such as point mutations (single nucleotide changes), insertions or deletions of nucleotides, or rearrangements of DNA segments. These changes can alter the sequence of a gene, leading to a mutation that may affect the function or expression of the gene. Factors such as environmental exposures or errors during DNA replication can contribute to these changes.

How do a DNA molecules make a copy of itself?
About 55 F and 65 C or the exact oppict.

Is RNA a disposable copy of DNA?
RNA is not a disposable copy of DNA; it is a nucleic acid that plays important roles in the synthesis of proteins and other cellular processes. RNA carries genetic information from DNA to the ribosome for protein synthesis through the process of transcription and translation.
