Suppose a 100-base-pair, double-stranded DNA molecule consists of 23% cytosine bases. How many total hydrogen bonds are holding the two strands together? Approximately how many nucleotide bases are in the human genome? How many DNA molecules will be found in each cell at the end of anaphase...
How many nucleotide bases does a codon consist of? Does transfer RNA carry codons? How are messenger RNA and transfer RNA similar? Is transfer RNA a protein? What is a segmented RNA virus? How many different kinds of proteins does one cell contain?
How much ATP would a cell use to make a protein of 330 amino acids? How many different kinds of proteins does one cell contain? How many different proteins are there in the complement system? A hypothetical gene 900 nucleotide long can code at most for a protein of how many amino acids...
A reexamination of the nucleotide incorporation fidelity of DNA polymerases. Biochemistry 41, 10571–10576 (2002). The authors of this article posit, for the first time, that the main step that controls the fidelity of DNA polymerase catalysis should be the chemical step. Article CAS PubMed ...
Streptococcus suis is a zoonotic agent that causes sepsis and meningitis in pigs and humans. S. suis infections are responsible for large economic losses in pig production. The lack of effective vaccines to prevent the disease has promoted the extensive
The guide RNA is paired with a Cas9 enzyme to make edits in the genome. Once the RNA binds to the desired sequence, the enzyme swoops in and cuts both strands of DNA. In response, the cell attempts to glue the strands back together, but it uses a fault-ridden process that often intro...
or constitutively from different synonymous messenger RNA (mRNA) variants. A synonymous mRNA variant is an mRNA molecule where one or more codons have been replaced by a synonymous codon, which does not alter the encoded protein’s primary structure but alters the mRNA’s nucleotide sequence. ...
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 pai...
How many codons were in the mRNA? How many amino acids were present in the final protein chain created in translation? Explain the differences in the two numbers of mRNA codons and amino acids in the protein. Explain your answers. During transcription, h...
How is DNA different from RNA? What 3 ways does RNA differ from DNA? How is a DNA nucleotide different than an RNA nucleotide? How do DNA and RNA differ? a. DNA is double-stranded while RNA is single-stranded. b. They have different sugars. c. Thymine is present in DNA but not in...
