What is the part of a strand of DNA with regulatory sequences?
The part of a strand of DNA with regulatory sequences is called the promoter region. This region is located upstream of the coding region and contains specific sequences that interact with regulatory proteins to control gene expression. The promoter region plays a crucial role in initiating the transcription of the gene.
Why can you predict the base sequences and a DNA molecule of DNA if you know the sequence of the other strand?
You can predict the base seqences of a DNA molecule if you know what one strand is, because of double Stranded DNA. Each strand matches up with a letter and repeats a pattern throught the entire DNA strand.
What initially determines which DNA strand is the template strand and therefore in which direction RNA polymerase ii moves along the DNA?
The promoter region of a gene contains specific sequences that signal RNA polymerase II where to bind and initiate transcription. The orientation of these sequences determines which DNA strand is recognized as the template strand and therefore dictates the direction in which RNA polymerase II moves along the DNA during transcription.
What would the base sequences on the other strand of Dna be?
They would be described as being complementary - as in complementary base pairing.
At what part will DNA strand separate?
telomeres
The complimentary strand or matchig strand of DNA for tagtca would be?
It would be ATCAGT. A=T T=A G=C C=G for all the DNA sequences the complementary strand would be the opposite.
Which part of DNA is double helix?
The whole DNA strand is a double helix.
What is a part of DNA strand called?
Pyrimidines or Purines
How accurate is DNA testing of hair?
Very accurate to the base pair. The quality of the specimen matters as DNA can degrade. Short strand sequences (10-12 base pairs) can still be determined by PCR from one strand of hair.
How does RNA polymerase attach to unwound DNA during transcription?
RNA polymerase attaches to unwound DNA during transcription by recognizing and binding to specific promoter sequences on the DNA strand. Once bound, the RNA polymerase begins to synthesize a complementary RNA strand using the DNA template.
DOES THE mRNA MODEL MORE CLOSELY RESEMBLE THE DNA STRAND FROM WHICH IT BWAS TRANSCRIBED?
Yes, the mRNA model closely resembles the DNA strand from which it was transcribed, specifically the coding or sense strand. The mRNA sequence is complementary to the DNA template strand and contains uracil (U) instead of thymine (T). However, while they share similar sequences, mRNA is typically single-stranded and undergoes modifications like splicing, capping, and polyadenylation, which differentiate it from the original DNA strand.
What is the strand?
The template strand, if reffering to DNA, is the strand of the DNA that is copied to make more DNA.
