Answer:
Uses each strand of a DNA molecule as a template for the creation of a new strand. (Option A)
Explanation:
DNA replication: It is defined as the uses of each strand of a DNA double helix act as a template for the creation of a new complementary strand. During the process of DNA replication, one leading strand (new strand) is made as a continuous piece and another lagging strand is made in small pieces.
DNA replication process, in addition to DNA polymerase, requires other enzymes such as DNA ligase, DNA helicase, DNA primase, and topoisomerase. DNA polymerase is the key molecule in the DNA replication, it is responsible for the synthesizing DNA. They help to add one by one nucleotide to the growing DNA chain and incorporating only those which are act as complementary to the template.
Answer:
i assume you want the gap filled
Explanation: that does not CONDUCT electricity
Answer:
Hypermethylation of___ promoters will lead to reduced expression of the correspondent genes. Some genes such as Cell Cycle stop genes _and__DNA repair genes_need to be expressed. When they__are not expressed_, this can lead to cancer.
Explanation:
Oncogenes are genes that may trigger cancer, where they are generally overexpressed (i.e., expressed at high levels). Although there are well-documented exceptions to this rule, DNA methylation generally represses gene expression by preventing the binding of transcription factors to promoters. It is known that the hypermethylation of tumor suppressor genes including, for example, cell cycle stop genes and DNA repair genes, may lead to cancer. Similarly, hypomethylation of oncogenes such as, for example, Cyclin D1 (a cyclin-dependent kinase involved in cell cycle progression), may also contribute to carcinogenesis.
