However, the length of the telomere determines the number of times the cell will divide. Why do telomeres shorten? At the end of replication, RNA primers are removed. A small length of DNA is lost when the final RNA primer is removed. This small length of DNA is part of the telomere....
DNA Replication:DNA replication is the process of making two identical copies of DNA from one parent molecule. DNA replication is important because it creates the new DNA needed for cell division.Answer and Explanation: The purpose of DNA helicase is to unwind DNA for DNA replication and ...
DNA methylationEpigenetic age accelerationPsychosocial well-beingPsychosocial risk factors have been linked with accelerated epigenetic aging, but little is known about whether psychosocial resilience factors (eg, Sense of Purpose in Life) might reduce epigenetic age acceleration. In this study, we tested...

Expression and structure of the human NGF receptor Dan L. JohnsonAnthony A. LanahanC.R. Buck...Moses V. Chao Cell Nov 1986 The nucleotide sequence for the human nerve growth factor (NGF) receptor has been determined. The 3.8 kb receptor mRNA encodes a 427 amino acid protein containing a...
As a result, DNA methylation would represent a molecular mechanism extending the plasticity and flexibility of phenotypes produced by a given genotype. As a model, we used the clonal fish hybrid Chrosomus eos-neogaeus (Cyprinidea and Pisces). We chose this system because a given clonal lineage ...
Spacer DNA:Spacer DNA refers to certain areas present in the non-translated DNA molecules between transcribed repeated genes. Its helps in ensuring the high paces of transcription related to these genes. Nucleotide sequence of the spacer DNA is not monitored demonstrating that whatever the functi...
These include the monitoring of enzymatic reactions (nucleases [19], ligases, DNA phosphorylation, and methylation) [20], real-time pathway analysis of living cells [18], the study of protein–DNA interactions [20], bioimaging, gene therapy, drug delivery, genotyping, analysis of PCR products,...
a) How is DNA transcription different than DNA replication/synthesis? b) What is the role of messenger RNA (mRNA) during DNA transcription? c) What happens to the mRNA after transcription is complete (i.e., where does it go)? In what way does DNA methylati...
The collection of capillary blood microsamples via finger-prick has several advantages over traditional blood collection. It is considered convenient and more patient-centric, enabling collection of the sample by the patient at her/his home with subseque
