How do the different DNA nucleotides pair during DNA replication? How are RNA and messenger RNA related? What sugar distinguishes RNA from DNA? How are DNA replication and protein synthesis different? A) What are DNA and RNA? B) How are they alike and different? C) How do they help each...
How do nucleotides get into the nucleus?Question:How do nucleotides get into the nucleus?A Short Description of Replication:Replication is the process by which the cell multiplies itself. It starts with the multiplying of the genetic material. Afterward, the nucleus divides in half containing each...
Learn about polynucleotides. Understand what a polynucleotide is, how nucleotides are linked together to form a polynucleotide chain, explore its...
S phase has checkpoints if there is not enough nucleotides to build the new DNA molecules or if the DNA molecule breaks. Cell cycle may pause or stop What are the last checkpoints before cell division G2 checkpoints are the last checkpoints before cell division During the G2 checkpoints ...
A pair of mutually antisense ORFs can overlap with each other in three different reading frames. That is, the codon positions in the two ORFs can either perfectly overlap or be offset by one or two nucleotides. The constraints on the co-evolution of the two ORFs would be different in the...
each of which is attached to a pentose sugar and a phosphate molecule. Together, they are known as a nucleotide. These nucleotides are arranged in two long coiled strands like a hair braid. The bases on the two strands pair up with each other; A with T and G with C, forming base pa...
Let’s now put the abstract calculations into action and study the energy budget of a specific molecule: a prominent neural protein implicated in synaptic plasticity,CaMKIIα.CaMKIIαproteins contain 478 amino acids, its transcripts have ~4900 nucleotides99, and an average dendritic spine contains ar...
All genes are made up of stretches of these four bases (arranged in different ways and in different lengths). You can view a 3-D rotatable image of DNAhere... Photo: National Institute of Health A critical feature of DNA is the ability of the nucleotides to make specific pairs: . Adeni...
What is the structure of a nucleotide? What are DNA's four nucleotides, and how do they pair up? (a) What is the structure of a nucleotide? (b) What are DNA's four nucleotides, and how do they pair up? How is the structure of DNA different from the structure of RNA? Dr...
How is gene expression regulated at the chromatin structure level? What role do histone proteins play in packaging DNA within nuclei? Explain how electrophoresis separates DNA strands. How can the structure and function of nucleotides (DNA and RNA) allow the cell to assemble specific proteins with...
