Which of the following strings of amino acids can be decoded

1 answer:

8 0

The correct answer choice among the statement above about strings of amino acids which can be decoded using single letter amino acid abbreviations to a type of

secondary structure is:

Alanine luecine proline histidine alanine histidine glutamic acid leucine isoleucine cysteine glutamic acid serine. Option a is the correct answer

The structure of mature messanger RNA encoding the average eukaryotic proteins is: 5' cap, 5' UTR, coding region, 3' UTR, and poly(A) tail. Option a is the correct answer

The correct answer choice which is extrinsic is: the TATAAT consensus sequence at the -10 posi!on of prokaryotic promoters

The diagram solution of the coding strand, 3’, 5’, translation on, transcription replication to the last isquestion is attached

<h3>Amino acid</h3>

Amino acid can simply be defined as those organic molecules or substances which combine to form proteins. However, amino acids are generally characterized by some key features or properties; some of these properties of amino acids includes the following:

They are soluble in water
They are base units of proteins
Amino acid are insoluble in organic solvent
Amino acids are colourless
They are crystalline solid
All amino acids however too, have at least one acidic carboxylic acid (-COOH) group and one basic amino (-NH2) group.

So therefore, the correct answer choice among the statement above about strings of amino acids which can be decoded using single letter amino acid abbreviations to a type of

secondary structure is:

Alanine luecine proline histidine alanine histidine glutamic acid leucine isoleucine cysteine glutamic acid serine. Option a is the correct answer

In a cell, a gene codes for a nucleic acid known as mRNA, and mRNA codes for proteins. Just four nucleotides can combine to code

Lyrx [107]

As mentioned in the question, all the proteins in our cells (and there are many - diverse as they are numerous) arise essentially from four nucleotides - A, C, G, and T - in DNA. These stretches of DNA (known as genes) code for mRNA (the "m" standing for messenger, as these molecules carry a message from the nucleus to the cytoplasm), which again are made up of just four different nucleotides - A, C, G, and U. How these nucleotides code for amino acids was a point of contention between scientists for many years, with Francis Crick (co-discoverer of the structure of DNA) arguing for a complex and overlapping two-nucleotide system. The truth is much simpler. The four nucleotides can combine to form various three-letter arrangements (sixty-four, to be exact) known as codons. One codon codes for a "start" codon, three codons for a "stop" codon, and the remaining codons for the other amino acids. The more eagle-eyed quizzer will see that the numbers don't quite add up (sixty codons, but only twenty amino acids?). In fact, the "start" codon codes for the amino acid methionine. The remaining nineteen amino acids share the fifty-nine remaining codons, with some amino acids being coded for by more than one codon (arginine alone is coded for by six codons!).

The ribosome is an interesting beast. It is a small but complex machine of the cell which firstly recognises the mRNA codons, and then recruits molecules known as tRNA (the "t" here stands for transfer) which deliver the appropriate amino acids. It consists of a "large" subunit and a "small" subunit, which work together poetically to create proteins from mRNA codes - a process known as translation. Ribosomes are a mixture of proteins and nucleic acids, and it came as somewhat of a shock to the scientific community to realise that it was the nucleic acid (and not the protein) which carries out the catalytic activities of the ribosome. This finding, deduced from detailed structural analysis of ribosomes, earned Venkatraman Ramakrishnan, Thomas A. Steitz and Ada E. Yonath the 2009 Nobel Prize for Chemistry.

HOW TO<br> PROJECT: PUNNETT SQUARES<br> NEED HELP :(

cluponka [151]

What do you need help with? One of the biggest things to remember with Punnett squares is that when you cross them you need to make sure the dominant trait (Upper case letter) is in front of the recessive trait (lower case letter)
