Concept explainers
(a)
To determine: The possible RNA molecules from the given human DNA.
Introduction: DNA or deoxyribonucleic acid can be defined as a molecule consisting of all the genetic information. It is comprised of two chains which coil to form a double helix structure.
(b)
To explain: The translation of only one out of two RNA molecules.
Introduction: In the process of translation, the synthesis of proteins occurs with the help of ribosomes or endoplasmic reticulum. The translation process has three phases which include initiation, elongation, and termination.
(c)
To determine: The amino acid sequence for vasopressin if the RNA molecule that can be translated is mRNA for hormone vasopressin.
Introduction: Vasopressin is an antidiuretic hormone and is released from the pituitary gland. In the body, this hormone is responsible for the regulation of water balance in the blood.
(d)
To explain: The vasopressin in its active form is nonapeptide with cysteine at the N-terminus.
Introduction: Vasopressin is an antidiuretic hormone and is released from the pituitary gland. In the body, this hormone is responsible for the regulation of water balance in the blood.
(e)
To determine: The way to change DNA that encodes vasopressin to encode for oxytocin and also suggest the evolutionary relationship between genes for vasopressin and oxytocin or not.
Introduction: Vasopressin is an antidiuretic hormone and is released from the pituitary gland. In the body, this hormone is responsible for the regulation of water balance in the blood.

- True or False. Explain. A) At no time during protein synthesis does an amino acid make direct contact with the mRNA being translated. B) Because the two strands of DNA are complementary, the mRNA of a gene can be synthesized using either strand as a template.arrow_forwardTyped explanation only Codons in mRNA molecule and their corresponding amino acids UUU Phenylalanine UAU tyrosine UUA leucine UAA nonsense GCA alanine AAU asparagine AAG lysine UGC cysteine GUU valine UCG, UCU serine Refer to Table 8.2.

- True or False. Just write T if it is true and F if it is false. In E. coli both RNA and protein synthesis take place in the cytoplasm. Okazaki fragments are ssDNA CHAINS OF 100-200 nucleotides long, primed by very short RNA primers in bacteria. In eukaryotic gene, the coding sequences are known as introns while the intervening sequences are the exons. The central dogma refers to the fact that proteins are products of information encoded in RNA using a DNA intermediate. The ends of the linear chromosomes are maintained by telomerase to prevent it from shortening during mitosis. The Shine Delgarno sequence is where the RNA pol binds during transcription in prokaryotes The sigma subunit of the E. coli RNA polymerase confers specificity to transcription. Both DNA replication and transcription follow a 5’ to 3’ direction of polarity. Nucleosomes are the structural unit of chromatin. In the lagging strand, the enzyme X removes RNA primers attached by PRIMASE and this gap is then filled…arrow_forwardTrue or False. De-acetylation of histone tails allows nucleosomes to pack together into tighter arrays, which usually reduces gene expression.

The following sequence of nucleotides is found in a single-stranded DNA template: ATTGCCAGATCATCCCAATAGAT Assume that RNA polymerase proceeds along this template from left to right. a. Which end of the DNA template is 5′ and which end is 3′? b. Give the sequence and identify the 5′ and 3′ ends of the RNA transcribed from this template.arrow_forwardPlease convert it to past tense and passive voice. Each group will be provided with two 20 g double-stranded DNA oligomers A and B in STE buffer (0.1M NaCl/ Tris/ 10 mM EDTA, pH 7.4).
