Genetics - 10 Basic Questions

Telomerase contains RNA

rRNA, mRNA, tRNA respecively

The estimated number of human genes is 20 to 25 thousand. This is based on current scientific knowledge and research, which suggests that the human genome contains a relatively small number of genes compared to earlier estimations. Advances in genetic sequencing technology and analysis techniques have allowed researchers to refine their understanding of the human genome and identify the actual number of genes present. This estimate is widely accepted in the scientific community.

It is the least conserved. H1 binds to linker DNA.

AGA, AGG, UAA, UAG are the 4 mitochondrial stop codons.

2 rRNA, 22 tRNA, 13 proteins of ETC ===> total 37

that's why they are known as restriction enzymes.

The Hogness box is the equivalent of the pribnow box in eukaryotes. The pribnow box is a DNA sequence found in prokaryotes that serves as the binding site for RNA polymerase during transcription initiation. Similarly, the Hogness box is a DNA sequence found in eukaryotes that functions as a promoter element for RNA polymerase II. It helps in the initiation of transcription by providing a binding site for transcription factors. Therefore, the Hogness box is the correct answer as it is the equivalent of the pribnow box in eukaryotes.

The human haploid genome consists of 3 billion base pairs. This is the correct answer because the haploid genome refers to the set of chromosomes in a gamete, which contains half the number of chromosomes found in a normal body cell. The human genome is diploid, meaning it consists of two sets of chromosomes, one from each parent. Each set contains approximately 3 billion base pairs, resulting in a total of 6 billion base pairs in a diploid genome. Therefore, the haploid genome, which represents only one set of chromosomes, contains 3 billion base pairs.

thymine is methylated uracil
