1.Explain how the TATA box and transcription

Biology
1 answer:
jeka943 years ago
5 0

Answer:

The TATA box is an alternating sequence of Adenine and Guanine nucleotides that transcription factors bind to. The TATA box is found just before a gene. The transcription factors tell the RNA polymerase where to bind to begin transcription. This ensures the RNA polymerase will know where to start and which gene to transcribe.

In a praticular breed of cattle, a black coat is dominant over a red coat. If a cow with a red coat is crossed with a black bull
steposvetlana [31]
You are correct :) Red coat's genotype would be tt and the black bull's genotype would be Tt. You put those in a punnett square, and you'd get 2 tt's and 2 Tt's. Hope this helps! :D

The scientists mapping the SNPs in the human genome noticed that groups of SNPs tended to be inherited together, in blocks known
Over [174]

Answer:

SNPs have shown that only 0.1 % of DNA sequences are different in the human genome between different individuals, thereby all the inherited phenotypic variation observed in our species is associated with only 0.1 % of differences at the genome level  

Explanation:

Haplotypes are block-like sequences of DNA that are inherited together due to low recombination rates. Moreover, single-nucleotide polymorphism (SNP) mapping is a very useful methodology used to map the site of SNP mutations (i.e., SNP variants). In this regard, it has been observed that there are approximately 10 million common SNPs in the human genome. These SNPs contribute to the wide range of phenotypic variation observed in human populations for different traits (e.g., eye color, hair, weight, height, etc). Moreover, researchers have determined that SNPs can be clustered into haplotypes, thereby haplotypes can be accurately sampled by as few as approx. 300,000 selected SNPs, which are sufficient to represent all of the genetic variation across different human genomes.
