The genome is defined as the total genetic library of a cell. It is estimate that in humans, the genome codes for about 25,000 different genes.
You are watching: Which rna base bonded with the thymine?
Chromatin is the DNA-protein complex and is organized as a long, thin fiber. Chromosomes are densely-packed chromatin, wrapped around proteins called histones. The centromere is the region of a condensed chromosome that connects sister chromatids to each other, and is the site at which the spindle fibers attach during mitosis in order to move them about the cytoplasm.
In DNA adenine (A) bonds to thymine (T) and guanine (G) bonds to cytosine (C). What is the bonding scheme in RNA?
In RNA, thymine is substituted by uracil. So adenine will bond to uracil instead of thymine when RNA interacts with DNA and when RNA folds with itself to make a 3-dimensional structure.
Uracil is a nitrogenous base that is only found in single-stranded RNA—it is not found in DNA. Thymine pairs with adenine in DNA, whereas in RNA, uracil pairs with adenine.
Uracil is the base pair that is used in ribonucleic acid (RNA) in the place of thymine. The other three bases adenine, guanine and cytosine are found in both DNA and RNA.
Uracil is only found in RNA under normal conditions. It replaces thymine, which is only found in DNA. Therefore, thymine, adenine, cytosine, and guanine are the bases found in DNA, and uracil, adenine, cytosine, and guanine are the bases found in RNA.
Watson and Crick were the two scientists who developed the model of DNA as a double helix in 1953.
Uracil in RNA bonds to adenine on the DNA template during transcription. These two nitrogenous bases form two hydrogen bonds.
mRNA contains uracil instead of thymine, therefore your answer should not contain the base thymine. Remember, DNA is read in the 3″ to 5″ direction and the corresponding strand is created in the 5″ to 3″ direction. It is important to pay attention to polarity of the strands. Adenine pairs with thymine, and/or uracil. Guanine pairs with cytosine.
Which of the following RNA molecules transports amino acids to ribosomes to be used to assemble the protein molecule?
mRNA is messenger RNA, it carries the genetic code that determines the protein. snRNA directs splicing of pre-mRNA. tRNA transports the amino acids used for assembling proteins. rRNA is a component of ribosomes (the other component is protein). pre-mRNA- single strand of RNA processed to form mRNA.
